When people talk about AI activation, they usually mean the moment something gets automated. A workflow runs. A task is completed. A demo works.

That framing misses the point.

At helvia.ai, we do not think of activation as “the first automation.” We think of it as onboarding a digital employee.

What We Mean by “Digital Employee”

By digital employee we simply mean an AI agent built for a specific role, with clear responsibilities, boundaries, and access to the right company knowledge and systems.

A Digital Employee Has a First Day, Too

When we talk to a new client about building an AI agent, we deliberately use the analogy of hiring an employee.

Not because it sounds nice, but because it sets the right expectations.

Hiring an employee does not mean they become productive the moment they show up. You onboard them. You explain how the business works. You give them documentation. You define responsibilities, boundaries, and what “good work” looks like.

An AI agent is no different, with one critical distinction: You cannot talk to it.

You Cannot “Walk It Through” Things

A digital employee cannot ask clarifying questions. You cannot take it aside and explain something again. You cannot rely on shared assumptions.

The only way it understands how to do its job is through what you give it upfront.

That means written instructions describing the Job To Be Done, the individual steps of the job, supporting manuals, policies, FAQs, procedures, clear definitions of what is allowed and what is not, escalation rules, and concrete examples of correct outcomes.

It also means the content needs to be in the right format and structure to be digestible by an AI. If knowledge is scattered, inconsistent, or buried inside long documents that mix multiple topics, the agent will struggle to retrieve and apply it correctly. Clear structure directly impacts answer quality and reliability.

If something is unclear, missing, or contradictory, the agent will not raise its hand. The only way you notice is by observing how it behaves in real situations.

When it does something wrong, the root cause isn’t a “bad digital employee.” Usually, it is unclear instructions, missing documentation, conflicting rules, poorly structured content, or scenarios that were never written down because they were considered obvious.

The Hidden Work Is the Real Work

This is where most teams struggle.

Many business processes across industries are executed “by default.” They live in people’s heads. They are rarely documented because everyone assumes they are understood.

For a digital employee, nothing is obvious. If it is not written down somewhere, it does not exist.

In most organizations, the first blocker is not model quality, it is missing or implicit process knowledge. Our onboarding approach includes a content readiness pass, role and escalation design, and a supervised evaluation phase, so the agent earns trust before it scales.

That is why, when the material is missing, our first job is not to “train the AI,” but to help the client understand what needs to be created, what already exists, where the source of truth is, and how much effort it will take to make this usable, including bringing the content into an AI-friendly structure.

Only then can the agent be onboarded properly.

So When Does Activation Actually Happen?

From this perspective, activation is not the first automated task.

Activation happens when the digital employee has received its onboarding material, the instructions are clear and complete, the knowledge is structured in a way the AI can reliably use, and it has proven, in a real scenario, that it can perform its role correctly.

It is the moment when the user says:

“OK, I can delegate this.”

That is the first real day at work.

If you're considering an AI agent, we offer a 60-minute Digital Employee Readiness Check. Most companies discover they're not as ready as they thought, which saves months of false starts. You'll leave knowing exactly what you need to prepare before activation makes sense.

Helvia.ai was recently featured in Startupper MAG (#68), one of Greece’s leading entrepreneurship and innovation publications. In the interview, our co-founders Stavros Vassos and Dimitris Balaouras discussed the current state of Artificial Intelligence, the myths around an “AI bubble,” and why the real opportunity lies not in hype—but in digital labor powered by AI Agents.

Below, we’re sharing the key insights from that conversation, translated and adapted for our global audience.

AI Bubble or AI Boom?

The excitement around AI is undeniable—but so is the growing skepticism. Are we heading toward another tech bubble, or are we witnessing a genuine transformation?

According to Helvia.ai, the answer depends on which narrative you focus on.

There is indeed a level of hype, especially around AGI (Artificial General Intelligence)—the idea that machines will soon think and learn like humans. This narrative often comes with inflated promises that don’t reflect today’s technological reality. That’s where the perception of an “AI bubble” comes from.

However, there’s a second, far more grounded narrative: digital labor.

AI Agents are already operating in real production environments. They automate tasks, improve productivity, reduce operational costs, and integrate directly into business workflows. This is not a future vision—it’s happening now. This is the real AI boom.

For businesses—especially in markets like Greece—this shift represents a major opportunity. Companies that move beyond hype and adopt AI pragmatically can gain a significant competitive advantage, even against much larger organizations.

Why Companies Trust Helvia.ai

Many of Helvia.ai’s clients come with one of two challenges:

• They have specific, high-value use cases but lack the in-house expertise to implement them.
• They’ve already experimented with AI pilots that never made it to production.

What they find at Helvia.ai is not promises of “magic AI,” but real, production-ready digital labor.

Helvia works as a long-term partner, not just a technology vendor—co-designing solutions, implementing them, and continuously improving them based on real usage.

This approach is built on three core pillars:

1. Value-first solution design
   Clear scope, measurable KPIs, risk assessment, guardrails, and a realistic rollout plan from day one.
2. A production-grade AI Agent Platform
   The Helvia.ai Agent Platform includes built-in capabilities such as testing, versioning, logging, evaluation, integrations, and monitoring. This allows teams to focus on where value is created—process mapping and workflow integration—rather than rebuilding infrastructure for every project.
3. Clear boundaries and governance
   Agents are designed with explicit rules: when to respond, when to ask for clarification, and when to escalate to a human. This is critical in real business environments where operational risk matters.

All agents are continuously monitored in real conversations after go-live, allowing teams to identify failures early and apply targeted improvements.

What’s Next: Helvia.ai Agent Platform 6

Helvia.ai is currently finalizing Helvia.ai Agent Platform 6, scheduled to launch in early 2026.

This new version marks a major step forward in how AI Agents are designed, managed, and optimized, built around two core components:

• Designer - A powerful environment for building agentic workflows that combine multiple Large Language Model calls, enabling more intelligent, flexible, and robust agent behavior.
• Observatory - A comprehensive analytics and insights layer that gives organizations full visibility into agent performance and actionable, data-driven insights for continuous optimization.

With a strong focus on usability and UX, the platform gives organizations complete control and transparency over their AI ecosystem.

Why So Many AI Projects Never Reach Production

Despite widespread experimentation, many AI initiatives never make it beyond demos.

The most common reasons?

• Lack of a clear business use case
• Unrealistic expectations about current AI capabilities
• A tech-first mindset instead of a value-first approach
• Underestimating integration complexity with existing systems
• Ignoring organizational culture and adoption
• Treating AI Agents as “just prompts” rather than fully governed, monitored, and owned components of real workflows

Without proper governance, monitoring, and ownership, projects stall before delivering impact.

Practical Advice for Companies Starting with AI Agents

For organizations beginning their AI journey today, Helvia.ai offers clear guidance:

• Choose partners who know how to take AI to real production, not just demos.
• Start with clear, well-defined use cases and KPIs from the beginning.
• Move iteratively—from pilot to scale—rather than attempting risky, large leaps.
• Don’t be afraid to start simple. A small, focused agent can evolve into something much more powerful through real usage and continuous improvement.
• Invest early in data quality and production integration.
• Aim for small, consecutive wins, not one big bet.

The future belongs to the AI-native enterprise—and the encouraging news is that this future is more accessible than ever, even for small and mid-sized companies.

By Stavros Vassos, Co-Founder & CEO at helvia.ai

This post is based on a recent talk I gave at the 4th GenAI Summit on the 24th of November, 2025. You can find the slides of my presentation here and the recording of the full session here. My intention in the talk and this writeup is to share some thoughts on three things that I see people asking all the time about AI:

1. Is it an AI Bubble or AI Boom?
2. How can I benefit from AI Today?
3. What is a promising technical path forward?

First, I'd like to go through a quick overview of the last three years with GenAI.

Three Years of GenAI: A Rapid Transformation

The time of my talk (November 24, 2025) marked almost three years since ChatGPT first introduced Generative AI (GenAI) and Large Language Models (LLMs) to the world.

Key milestones include:

• November 30, 2022:  ChatGPT by OpenAI came out and shocked everyone with what was possible at that time! At the time it was using a version of GPT-3.5 that was called "InstructGPT".
• March 14, 2023: Then a few months later GPT-4 came out and shocked everyone again with more capabilities that were considered an order of magnitude more powerful! Then not other big shocks took place but lots of things happened.
• April 18, 2024: Llama 3’s by Meta release set a framework for open source (OSS) models enabling progress and growth in LLM providers.
• June 21, 2024: Almost 1.5 year ago Claude 3.5 is released by Anthropic, shortly becoming the "coding king," and essentially making coding a prominent use case for LLMs. This led all major LLM vendors to develop models specifically tailored for coding.
• November 2025: If we look at just the last couple of weeks, we see a new release of the latest version of LLMs by many major vendors (including GPT-5.1, Gemini 3, Claude Opus 4.5), as well as open source models (Kimi K2 Thinking, DeepSeek 3.2) that seem to be on par with the closed source models that are leading the race. 

In just three years, LLMs became the cornerstone of a new tech stack, and a rapidly evolving ecosystem that blends research and development of new applications and services.

AI Bubble or AI Boom? Two Visions of the Future

There is a wild spectrum of expectations about AI and there are passionate debates about whether AI works or not. Let’s look into two common perspectives:

• “Existential” Vision: AI will evolve to Artificial General Intelligence (AGI).
• “Industrial revolution” Vision: AI will bring us Digital labor.

1. The “Existential” Vision: AGI

According to this vision, AI will bring us Artificial General Intelligence - AGI. There are many definitions for this, let's go with the following for today. If you have an AI system that can perform equally or better than any human on things you can do while sitting on a computer, then we have AGI.

What AGI means

• Super-intelligence! Many people believe that since AI iterates faster on its capabilities than a person, ΑΙ bootstraps itself to unbounded skills.
• Which means that AGI essentially brings unbounded acceleration on science, economy, everything really.
• And to many it also means that there is a possible extinction of humanity.

Either way, whoever gets there first will have tremendous advantage! No wonder literally hundreds of billions of dollars are invested on the frontier labs pursuing larger LLMs and AGI.

Is AGI coming soon?

To be honest, I never thought nor had the feeling that this is going to happen soon. It's not an easy subject of course, and there is debate and strong opinions by very prominent figures in AI, e.g.:

• Geoffrey Hinton, widely known as one of the "godfathers of AI", has maintained many years now (one early reference can be found here) that we have just a few years to prepare ourselves before AI surpasses us.
• Yann LeCun, a high-profile AI researcher at Meta, has been arguing that LLMs are a dead-end and we need to start different lines of research (one recent reference here).

If they can't agree, how can you or me decide on this?!

Scaling toward AGI

One way to form an opinion is to see how things scale within the last few years. There is a quote from the CEO of OpenAI from almost a year ago that I think shows a common line of thought about how AI can grow to become AGI. It is from Sam's blog on February 10, 2025 and it goes more or less like this:

• The intelligence of an AI model roughly equals the log of the resources used to train and run it.
• These resources are chiefly training compute, data, and inference compute.
• It appears that you can spend arbitrary amounts of money and get continuous and predictable gains.

By the way, this is perhaps an optimistic view, especially coming from the CEO of a leading LLM company, and one whose funding relies on such assumptions about the future of AI. There is an important detail in this line of thought too: as mentioned in Sam's blog, the assumption is that the intelligence of an AI model roughly equals the log of the resources used to train and run it. Since log is not always easy to understand, let's see it with some examples of what this means (hand-wavy but true to the spirit of the assumption).

According to this:

• To "double” intelligence, you might need 10× the resources
• To "triple” it? Maybe 100× the resources
• To "quadruple" it? Maybe 1000× the resources
• This makes progress increasingly expensive and perhaps infeasible due to bounds on infrastructure or energy or.. earth size!

Overall, there is an indication that more resources will give us better AI and get us closer to AGI – but it could be 5 years or 500 years to reach AGI and may require other unconceived breakthroughs. Whether it's close or not seems to be more of a "gut feeling" and less of a predictable extrapolation of current results. So, let's say this is a "bubbly" expectation!

2. The “Industrial Revolution” Vision: Digital Labor

According to this vision, AI will bring us Digital labor, that is, digital employees that train themselves, onboard instantly, work 24/7, and cost less than human employees. This vision too is kind-of sci-fi coming to life, and at the same time there is lots of investment on supporting these new AI roles that will be working side by side or replacing human roles.

I would like to look into three prominent use cases where we see AI roles already being explored:

• Personal assistant
• Business automation
• Coding

AI roles - Personal assistants

Every “LLM app” like ChatGPT, Claude, Gemini, etc, acts essentially as a powerful personal assistant that operates on the digital world. Looking into some recent numbers about ChatGPT as reported by Financial Times:

• ChatGPT has more than 800 million regular users
• 5% of those are paying subscribers
• This amounts to 70% of OpenAI annual revenue

Judging from OpenAI alone, the personal assistant is probably the biggest use case of GenAI at the moment! And in fact, these AI personal assistants are already changing how we write and read text, how we search online, how we shop, and there is plenty of room to grow.

AI roles - Business automation

This is the core of the "Digital revolution" vision, according to which many human roles are going to be transformed into AI roles. Here we have mixed results. These are two articles coming from Gartner that are indicative of how this idea has evolved in the business world in the last couple of years:

• Gartner, Aug 2023: By 2026, investment in generative AI will lead to a 20% to 30% reduction of customer service human roles. (source)
• Gartner, Jun 2025: By 2027 50% of organizations will abandon plans to reduce customer service workforce due to AI. This shift comes as many companies struggle highlighting the complexities and challenges of transitioning to AI-driven customer service. (source)

The first article form a couple of years ago shows the initial excitement that in customer service we will have already replaced 20-30% of the human roles by today, while the second article of a few months ago reports on how this plan proves to be more difficult than initially thought. This is indicative of many cases trying to replace human roles entirely by so-called AI Agents. (Note: I got these two articles by a recent post of the AI Realist who does an excellent job fighting the hype!).

But what is an AI Agent exactly?

I often joke that an AI Agent is this mythical (AI) creature that is going to do all kinds of things and change our lives. There are plenty of definitions, most of them technical, e.g., a common one is that an AI Agent is an LLM-based system that is able to use so-called tools.

I like to use a more high-level definition that is more practical and helps understand what AI Agents represent today, and it goes like this:

Of course with LLMs we don't know exactly what they are going to write every time, there is this uncertainly. But with an AI Agent the uncertainty is about what they are going to do next: Are they going to send an email? Call an API? Send a message? Or something else?

AI Agents operate on an implicit tradeoff between these two desired qualities:

• Powerful – being able to handle scenarios that are not explicitly “programmed” for.
• Predictable – acting in the way an existing employee would handle things.

This is one of the major reasons why the promise of business using AI roles widely is not happening instantly. It is possible though, just not instant!

At Helvia.ai we have worked with large organizations and we have employed AI roles in business operations successfully and we have proved that you can get meaningful gains and ROI. The key is to do careful preparation and consider AI Agents in the scope of a wider Business and AI Transformation.

AI roles - Coding

Coding has become a very large niche and there is a long list of tools that apply to the whole software engineering lifecycle, some examples:

• New command-line tools (CLI): Codex, Gemini-CLI, GitHub Copilot, etc.
• New integrated development environments (IDE): Windsurf, Cline, Cursor, Antigravity, etc.
• New prototyping tools: Lovable, v0.dev, and others.

The high demand has led LLM providers create specialized models for coding and we see a release of something new every couple of weeks! In some sense, coding with AI is similar to business automation with AI, but the coding / software engineering environment is more structured and much faster to iterate, which makes it a great application domain for AI.

Results so far seem to show that AI can:

• Help junior software engineers learn faster if used as training aid.
• Assist senior engineers do the heavy lifting of projects.
• Change the way software engineers interact with information
  on the web.

Overall it provides the grounds for accelerating software engineering.

“AI Industrial Revolution” Vision – Are We There Yet?

So what's the verdict on this one?

What’s in it for You? How to navigate in this new world?

In practical terms, no bubble. In investment terms, it's another story. Let's say this in another way too. The technology is real: LLMs bring a new way of building "computers" and apps. It's the “Decade of AI Agents” in which we will transform culturally, socially, and operationally to incorporate new forms of autonomy in our personal and work lives. How can you make the most out of it now? I'd like to share some thoughts:

• At a personal level
• As an SME
• As an Enterprise

What’s in it for You As a Person

It's like all the leading labs are building flying cars and they give away free kits to try flying in your backyard! There is cutting-edge new technology being built every day and literally everyone can use the latest version of it as it comes out! In fact all major AI vendors offer a generous freemium and a ~$20 per month license for their personal assistant. This is a ticket to reinvent your interaction with technology, using AI as the ultimate interface to everything.

And how should you start? My personal favorite is if you don't know how to code, learn how to code! Or “vibe code” something for fun :) Here’s a mini game I did while creating this presentation, inspired by the bubble talk and an arcade game I used to play when I was young: Bubble Arcade by Helvia

What’s in it for You As an SME

As an SME typically there is no budget to build a tailored solution just for you, therefore you should not expect to get an AI Agent that solves exactly the problem you have in mind. However, you can use the built-in AI Agents on the Software-as-as-Service (SaaS) business applications you use, as every major SaaS provider is racing to add an in-app AI Agent on their offering. E.g., Atlassian offers Rovo to help with Jira, etc. Also, a more hands-on / DIY direction is to learn how to craft automation pipelines with AI-ready automation tools, e.g., use Make to setup email automations. There are hundreds of tools to use with affordable cost and great ROI to help you become the AI expert of your own SME.

What’s in it for You As a Large Organization

Let's first say that the AI Industrial Revolution is for you!

At this stage of technology and commercialization of LLMs, the AI Agents are most impactful when specialized on the actual business processes and requirements – and large organizations and enterprises are in the right position to make this happen as part of an AI transformation.

At Helvia.ai we have been working with enterprises almost 10 years now and we are happy to start a journey together to bring AI Agents in the places it makes more sense and brings more value – send us an email at contact@helvia.ai to get started if you are interested.

Looking Ahead: Beyond LLMs

Artificial Jagged Intelligence (AJI)

First, I would like to highlight something about the type of AI we have now. I like the term Artificial Jagged Intelligence (AJI) that Andrej Karpathy coined a little more than a year ago:

"The word I came up with to describe the (strange, unintuitive) fact that state of the art LLMs can both perform extremely impressive tasks (e.g. solve complex math problems) while simultaneously struggle with some very dumb problems."

There are plenty of examples of "silly" mistakes by LLMs, such as confusing that 9.11 is larger than 9.8 (which has to do with a way of interpreting 9.11 as a section number or a date, rather than a rational number).

My favorite one that you can try today has to do with visual models and generating images. If you ask a model to make an image transparent, most of the times what it will do is replace the background with a checkerboard pattern like this – which is something I actually tried earlier for this presentation on one of the latest and most powerful models.

I find this very interesting and it's a nice way to remind ourselves that the capabilities of the models today come to a great extend from reusing patterns they have "seen" at training time.

Why does this happen?

My guess is that most models struggle with generating transparent images because many images online that are marked as transparent are not available for direct download, and the training set did not include the actual transparent image to put as an example. Instead the training set probably included the preview of the transparent image online that looks like the real one but with a checkerboard background to highlight the transparency.

Neurosymbolic AI

And this brings me to a subject I am very fond of, namely, Neurosymbolic AI. As with many things with AI there are many definitions for this as well and it's an emerging field.

The easiest way to describe it is mixing methods and techniques from two disciplines in AI: the neural networks camp and the symbolic logic camp. I've been around in AI research enough to have seen an AI winter and an AI spring and to observe the shift of attention and power dynamics between these two camps. When I started my PhD the symbolic logic camp was ruling and the neural net camp was setting the stage for the dominating the field as it has done today.

It's interesting to observe these type of dynamics as it influences and sometimes defines the research that is visible to new researchers. For example now AI is almost (if not 100%) synonymous to neural networks and perhaps Generative AI. But AI is not just this, it's a complex network of disciplines that is not easy to navigate if you are not an expert. Notably, the AI literature includes a long list of research on symbolic logic, knowledge representation, and a different type of automated reasoning than the one we are used to see in the LLM space.

Now as the LLM hype is settling down, we see that it's not easy or immediate to solve everything with simply writing instructions via prompting, prompt engineering, context engineering, etc. Moreover, we see the prompts becoming more of a programming language with their own coding-like constructs such as conventions about <final_answer_formatting>, <user_update_immediacy>, <frequency_and_length>, and more (as per the latest OpenAI prompt guide), as well as coding-based specifications for tools and APIs. Overall, specifying what an AI Agent should do is getting more structured on top of the "just say what you think in natural language".

This type of structure has been the cornerstone of the other camp of AI, with symbolic logic being a strict/formal form of writing instructions for AI systems. I strongly believe that there is an untapped potential in combining tools and tricks from the symbolic logic camp of AI to the LLM space and the neural net camp of AI. There is work already at different levels of synergy: from all the way down into training different kinds of deep network layers to all the way up to having an LLM use a symbolic AI system as a "subroutine" or tool to solve a particular type of problem.

For a quick intro see this recent position paper in the upcoming AAAI conference: The Future Is Neuro-Symbolic: Where Has It Been, and Where Is It Going? I am excited by all the spectrum of directions being explored, and I believe that there are low-hanging fruits in a "service-like" synergy where an LLM consults with one or more expert symbolic AI systems to get help.

Lots of Opportunities for Service-like Synergy

As an example, consider the way we typically handle memory for AI Agents. AI Agents often need to keep a persistent memory as a blackboard of past interactions and notes that can help them provide contextualized responses based on what worked (or not) in the past.

This is typically done using LLMs to write the notes, a retrieval mechanism for getting relevant notes, and using LLMs to revise the memories. For simple use cases this works effectively, but as things get more complex then you need to refine and tune how the memories are stored, how they are retrieved, e.g., using some more elaborate retrieval approach with semantic search, and how they are updated in light of new information.

At the same time, there is a large literature on research on they symbolic logic side, on “knowledge representation” and “belief revision” that formalizes the flow of information, the rules, the defaults and exceptions, and other useful machinery to make bookkeeping robust, fast, and inexpensive!

Consider also that even if LLMs work well for managing memories in some cases, it is often not an optimal approach in terms of speed and cost. For example, setting the updated set of memories through an LLM requires in the typical case to generate the whole new updated set of memories. Similarly, keeping a representation of the state for a complex task faces similar challenges. Both cases are central in how AI Agents work and when complexity increases there are benefits in crafting an optimized approach. To this direction, there are lots of "deliberation algorithms" for drafting hypotheses and getting conclusions which can be leveraged as tools as part of the thinking process of an LLM-powered AI Agent.

Anyway, I probably got too technical for the scope of this post!

Closing Thoughts

Closing, let's reiterate on a single message that is worth taking away with you today. It's an exciting time to be alive technology-wise but also culturally and socially. We seem to be the ones that will get to shape how AI technology will be adopted and incorporated in our society, or at least set some pragmatic basis. As for AGI, the biggest frontier seems to be the physical world, i.e., how AI systems can actually live and work in the space we live and operate.

To me we will reach AGI when a robot can navigate in Athens and survive running errands in the city 😄

Artificial Intelligence (AI) often comes with a mix of excitement and inflated expectations. Is it a magical solution to every problem, or simply another tool in our digital toolkit?

In a recent radio conversation on ERT News, our co-founder Stavros Vassos addressed exactly that — exploring what AI really is, what responsibility in practice looks like, and how it will shape our everyday lives in the years to come.

👉 You can listen to the full conversation in Greek here (starts at 1h 3m 30s).

No Magic, Just Engineering

“There’s a bit of a sense that there are magical solutions” Stavros noted during the interview. “As in: ‘Oh, we have something difficult, let’s just have AI do it.’”

The truth is more grounded. AI is not magic. At its core, it’s software — systems built with data, rules, and feedback. These systems learn from prior decisions, but they don’t design themselves. Behind every AI stands a team of people who define its logic and outcomes. And that means responsibility lies not with the machine, but with its creators.

Responsibility in Practice

Stavros made it clear that responsibility and governance must guide AI’s development and application. “Ultimately, whoever builds the system then has the responsibility to make it objective.”

This insight reminds us that AI is not a shortcut — it requires careful design, ethical frameworks, and ongoing oversight to ensure fairness, transparency, and accountability.

AI in Everyday Life

One of the key points from the radio conversation was that AI will continue to blend into our daily lives, often working quietly in the background.

“I think that as the next years go by and AI is applied and tested more,” Stavros said, “we’ll see it everywhere in the facets of our daily life, not necessarily visibly, doing things that help us.”

From customer service interactions to smarter decision-making in organizations, AI’s presence may be subtle — but its benefits can be transformative when deployed responsibly.

Takeaway: A Future Built on Responsibility

The ERT News discussion underscored an essential truth: AI is not about magic. It’s about engineering, governance, and human expertise. At helvia.ai, we see responsibility not as an afterthought but as the foundation for deploying AI at scale — making it a force that enhances, rather than replaces, human judgment.

Artificial Intelligence (AI) is actively transforming the way businesses operate today. From streamlining customer interactions to enhancing internal workflows, AI-powered assistants are at the forefront of this change. In a recent interview on Naftemporiki TV, Stavros Vassos, Co-Founder and CEO of helvia.ai, shared insights on how the company is driving this transformation and what the future holds for AI in businesses.

Can AI assistants help in decision making?

The answer is yes, and it's all thanks to the new possibilities of artificial intelligence. While it may seem a bit daunting at first, the difference we see now is in the quality and extent of the assistance. In the past, a digital assistant could only give us a directed answer or guide us to a specific source of information. However, now it's becoming more flexible and can cover even non-standardized topics, all while answering in the way we want it to.

One practical way this technology is aiding businesses is by allowing us to track the progress of our company through graphs and numbers. We can ask our AI assistant to create a graph for us on the spot or even take a few steps further. The predictions of the future with AI may be uncertain, but the last few years have shown an increase in the efficiency of AI in the digital world.

Greek innovation on the global stage 

Greece is very optimistic about its tech talent! Companies such as helvia.ai have made significant strides in the global market, proving that Greek companies can compete with the best, even in fast-moving sectors such as AI. It's worth noting that although Greece isn't one of the first countries to embrace new technologies, both in the private and public sectors, the potential of people, especially in research and technology, is very high. This enables technology companies to grow, and attract international customers.

How to keep up with the constant evolution of AI

As a company implementing and developing AI solutions, helvia.ai finds the rapid pace of progress refreshing. To keep up with this pace, we are constantly integrating and bringing new things to the table. However, for companies looking to adopt AI, it can be a challenge. With the current hype and trend, it can be difficult to understand what is right for your business and even how to ask the right questions. Additionally, it's hard to keep up with the technical details that are vital when explaining the differences between solutions. It's like trying to find the diameter of a pipe when buying a car.

Do companies in Greece keep up with the pace of AI adoption?

The pandemic has accelerated digitalization and forced a second wave of digital transformation, including the adoption of AI. In the past, falling behind was a risk for not undergoing a digital transformation. Now, falling behind is a risk for not implementing new techniques that require a digital transformation. This acceleration is creating a differentiation between those who are keeping pace and those who are falling behind.

What the future of AI holds

Despite the rapid progress we have witnessed so far, we have not yet seen the full potential of these developments. The speed of progress has been so great that we have been unable to predict the extent of its impact.

While we cannot say for sure what the next few years will bring, we do know that there is still much to be done to fully integrate and utilize the existing advancements in AI. Therefore, even though we may not see developments as significant as those we have witnessed so far, we still have a long way to go to productize and facilitate the adoption of the existing powers of AI.

We’d like to thank Naftemporiki TV for hosting us once again. The full interview is available in Greek here

Whether creating content, translating text or even developing code, the best results from AI models depend on how well you formulate your prompts, your request. Creating effective prompts can to a great extent improve the quality and usefulness of the responses you will receive. 

Helvia.ai co-founders Dimi Balaouras and Stavros Vassos recently shared some tips in an interview on Flash.gr on how to write better prompts when using an AI model to perform various tasks.  

Prompting tip #1: Give  the AI ​​model a role or persona

AI models have been trained in a specific way, and giving them instructions that resemble what they have seen during their training helps them follow instructions more accurately. Even if you assign the model a role or persona that it has not encountered before, it will find clues to match it with familiar roles and choose how to proceed.    

Prompting tip #2: Provide clear and specific instructions

Provide detailed instructions that outline the general direction, as well as specific steps. Avoid using self-evident language because an AI model may not interpret it as intended.  

Prompting tip #3: Include examples  

Provide two or three examples of input and output to give the AI model a more tangible idea of what you want. This technique, called Few-shot, helps the model produce more accurate and targeted results by allowing it to compare and correlate the provided material with what it knows.  

Prompting tip #4: Use punctuation marks

The concept is to make the prompt as readable as possible. The instructions should be presented as small bits and pieces, which are easy to pick out. If we write the instructions as we would say them, some information may be lost.  

When for example we use ChatGPT, we use plain text because there is no rich text editor to add formatting. To capture formatting, we use a simple formatting called Markdown. 

When giving a series of instructions, it helps the AI ​​model to divide the concepts into smaller units, separated by numbering and blank lines.  

Prompting tip #5: Use Imperative language

AI models follow instructions to a degree, depending on how clear they are, but not always 100% of the time. To make an AI model follow an instruction more systematically, use absolute language and "order" it to not deviate.  

Prompting tip #6: Include your own sources as bibliography

When asking an AI model for information, such as "what is the population of Greece?", it will answer based on what it has stored during training, or it will do a Google search and try to answer. If we need to rely on our own data, we must add our own sources either by uploading files or by writing along with the instructions.     

This usually requires additional tools and techniques to work well, such as the Helvia.ai platform that allows adding a knowledge base, e.g. from the customer service department and getting a digital assistant that responds based on that information alone.    

Prompting tip #7: Ask the AI model to think in logical steps (step by step)

This technique prompts the AI ​​model to write down its thoughts as it processes the query and produces the answer. It makes the AI ​​model's process of arriving at an answer more understandable to the user and enhances the accuracy in taking logical steps. As it writes them, it also uses them as a guide for continuation, almost as if it is "writing on the board" as it thinks.    

Prompting tip #8: Outline the steps the AI model needs to follow to answer correctly

Even if the AI model suggested the steps required to come up with the response, writing them down directs it to get closer to what we want. 

Prompting tip #9: Use the AI model one step at a time

When it comes to performing multiple tasks, it's best to break them into smaller pieces and ask the AI model to perform each one separately.

Example:

• First we ask the AI model to extract the details of the conversation e.g. the project the conversation refers to, the project owner and the subject of the email.
• Then we ask the AI model to make a summary of the email and translate it into English.
• Finally, we ask the model, using the project details and the summary from the previous two steps, to write an email in English to send to a colleague who does not speak Greek.

If we didn't break it down into steps and asked the AI model to do it directly, the quality of the answer would be limited compared to doing it in steps.  

By following these prompting tips, you can enhance the accuracy and quality of the AI model's responses. Giving the AI model a role, providing clear instructions, including examples, using punctuation marks and imperative language, providing sources, thinking in logical steps, outlining required steps, and breaking tasks into smaller pieces are all essential components to get the most accurate and high-quality responses from AI models. Implement these tips and see the difference in the AI model's performance.

Online retailers are always looking for ways to improve customer experience, and one of the ways they're doing this is by using AI shopping assistants. However, with so much information to sift through, these assistants can struggle to provide accurate and personalized recommendations using RAG. That's where Hypothetical Document Embeddings (HyDE) come in. By leveraging these technologies, retailers can improve the performance of their shopping assistants and provide customers with a more efficient and personalized shopping experience.

At helvia.ai, we recently engaged in a comprehensive discussion about the potential functionalities of a GenAI shopping assistant, focusing on how it could accurately identify the products a user desires or needs for specific tasks. This discussion provided the perfect setting to initiate an exercise I call "Product the Gap", which was designed to explore consumer needs ("Jobs") and possible solutions using the Jobs To Be Done (JTBD) framework. The insights gathered were visually represented on a Miro board.

In this blog post, we'll go through our approach using some real-life examples.

How to Leverage an AI Shopping Assistant with RAG and HyDE?

The Jobs To Be Done (JTBD) framework

The process began by addressing the primary question: What is the main job of someone looking to purchase a product online? From this, we formulated the core job statement (Main JTBD (1.0)): "Enable me to efficiently discover and select products that align perfectly with my specific goals and tasks, minimizing both effort and uncertainty throughout the decision-making process." This can be viewed on the Miro board, marked with a red sticker No. 1.0

To better understand the job context, we documented several job examples on the Miro board, each tagged with a red sticker (No. 2.x). Here, we will discuss The Bluetooth Example (2.2), which closely aligns with our solution:

"I want to buy a Bluetooth speaker for under $100 to use at pool parties."

Exploring how a user might currently find and purchase the best Bluetooth speaker under $100 for pool parties involves the following steps:

• Search Google for articles reviewing Bluetooth speakers.
• Identify waterproof models.
• Conduct a feature and price comparison.
• Decide on one.
• Research where it can be bought at the lowest price.
• Make the purchase.
• Alternatively, the user might:
• Ask friends for recommendations.
• Search for model reviews on Google.
• Compare prices.
• Complete the purchase.

Simplifying the JTBD process with AI

Our solution simplifies this process: by requesting "three Bluetooth speakers for use at pool parties under $100," our AI will offer three options from our e-shop, complete with brief descriptions and pricing. You can then select one, add it directly to the shopping cart, or visit the product page. The response from this request can be seen under sticker 2.2.2 on our board at perlexity.ai.

Identifying the Product Gap (2.2.3)
We compared our AI solution with traditional methods to understand where our approach improves functionality:

(+) Reduces time spent researching.
(+) Quicker in finding and selecting products.
(-) Uncertainty about whether the best option was chosen.
(-) Traditional preference for Google searches over querying bots.
(-) Higher trust in personal recommendations over bots or Google.
(+) More suitable for advanced users familiar with AI, like ChatGPT.

This analysis raised an important question: "How can we integrate a search form as the start of a chat conversation?" We plan to explore this further in our design phase.

Repeating the Exercise
It is beneficial to repeat this exercise with different examples in varied contexts to fully understand the constraints and potential of our solution across different scenarios.

How It Could Work (3.1)
Our solution relies on an AI Assistant metaphor that is able to search over the product catalogue in a more effective way, typically through a Retrieval Augmented Generation (RAG) pipeline. However, creating an appropriate knowledge base for RAG using e-shop product data presents a challenge: the product descriptions may not explicit mention references to the product's suitability for specific uses like pool parties..

One idea is to create Hypothetical Documents using a language model to generate additional information about products, such as writing product reviews, or describing ideal usage scenarios or even describe the image of the product . This enriched content could significantly enhance the knowledge base, enabling it to accurately fulfill queries like "suggest three Bluetooth speakers for use at pool parties under $100." This is actually supported by recent research on what is called "Hypothetical documents Embeddings" which shows improvements in similar scenarios.

What are Hypothetical Document Embeddings (HyDE)?

Let’s imagine an e-shop planning to introduce a new Bluetooth speaker specifically designed for pool parties. This speaker boasts features such as high water resistance, extended battery life, and powerful bass suitable for outdoor environments.

To aid the e-shop’s recommendation engine in accurately categorizing and suggesting this new product, hypothetical document embeddings can be created. The system would generate an imaginary product description incorporating key features of both pool party-friendly equipment and robust Bluetooth speakers. For example, it might include elements from existing durable, waterproof speakers that are known for high sound quality outdoors.

This hypothetical description helps the recommendation system understand how this new speaker aligns with potential customer interests who often search for pool party gear or outdoor sound systems. By training on this constructed scenario, the system can more effectively suggest the speaker to those looking to enhance their pool party experiences, ensuring targeted recommendations even before actual customer feedback is gathered.

Testing Hypothetical Documents

To evaluate the practical application of hypothetical documents, we used them with three real products:

Test 1: IKEA HEJNE 3 Shelves (3.2.1)

We generated the following hypothetical documents using ChatGPT-4 with these prompts:

• “Write a review for IKEA HEJNE 3 shelves”
• “Best use of HEJNE 3 shelves”

These hypothetical documents could facilitate queries such as "I want shelves for my garage" helping to efficiently retrieve the related product linked to the hypothetical document, which would not be possible to retrieve using just a RAG.

View the Hypothetical Documents on the Miro board, marked with a red sticker (No. 3.2.1).

Test2: Amazon T-Shirt (3.2.2)

We generated the following hypothetical documents using ChatGPT-4 with these prompts:

• “You are a stylist, can you describe the tshirt, what style it is and what other clothes I can match it with?”
• “You are a stylist, can you describe in the image what she is wearing, what style it is and what other clothes I can match it with?”

The hypothetical documents supported queries such as "I want a retro-style T-shirt to wear with a denim jacket."

Test3: Vacuum Cleaner (3.2.3)

We generated the following hypothetical documents using ChatGPT-4 with these prompts:

• “Can you write a review for Dreametech T30 Cordless Vacuum Cleaner, 90mins Long Runtime Stick Vacuum, 190 AW Robust Suction Handheld Vacuum, Cordless Vacuum with HEPA Filters for Hard Floor Stairs”
• “For what kind of use Dreametech T30 Cordless Vacuum Cleaner is best for?

The hypothetical documents assisted with queries like "I want a vacuum suitable for pet owners that is easy to store."

These examples showcase the potential of leveraging Retrieval Augmented Generation (RAG) systems with hypothetical documents to effectively bridge the gap between complex consumer queries and relevant product suggestions.

Google it vs Chat it 

During our exploration, two other significant insights emerged:

1. They typically think about which keywords will yield the best results for their desired outcome, rather than simply asking for what they want.
2. Users have been conditioned to use search engines rather than chatbots. 

How can we determine the specific purpose a user has in mind when searching for a product?

Building on the second point, it might be interesting to reverse the Jobs to be Done approach. For instance, when someone uses a search field, we could prompt the language model to identify potential jobs that need to be done. For example, if someone searches for “Household Vacuum,” we could use the LLM to ask, “Give me only the Category/Context of the top 10 JTBD for users looking to buy a vacuum, based on popularity.” Tagged with a red sticker (No. 4.1)

The response of ChatGPT4:

Certainly! Here are the Category/Contexts for 10 different JTBD scenarios for users looking to buy a vacuum:

Efficient Household Maintenance
Allergy and Health Management
Family and Child-Friendly Homekeeping
Flooring Versatility and Care
Pet Ownership and Care
Professional and Commercial Cleanliness
Space Optimization for Compact Living
Accessibility and Ease of Use
Sustainable and Eco-Conscious Living
Vehicle and Furniture Maintenance

Now, we can use this list to ask the user “What is the use you want the vacuum for?“ and then use the Hypothetical documents to provide product results.

How might we integrate the user search flow with AI-driven conversational flows?

Implementing a prompt beneath the search box that asks, “What is the use you want the vacuum for?” could serve as a method to integrate the user search flow with AI conversational flows.

However, I am confident that there is ample room to explore more effective solutions.

Taking Your Shopping Assistant to the Next Level with RAG and HyDE

As we wrap up this exploration into the evolving role of AI in shaping the future of online shopping, it’s clear that hypothetical documents and advanced retrieval systems like RAG can significantly enhance the way we search and discover products online. Our experiments with the "Product the Gap" initiative and hypothetical documents have opened up new pathways to connect complex consumer needs with precise product suggestions.

If you are interested in applying this AI-driven approach to enhance your own products, we would love to collaborate. Contact us to explore how these innovative technologies can be tailored to fit your business needs and elevate your customer experience.

Together, let’s continue to push the boundaries of what GenAI can achieve in the world of online shopping, making it more intuitive, efficient, and aligned with user expectations.

We would like to thank the Association of Thessalian Industries for the invitation and the opportunity to attend the event.

In a recent episode of Monokeros (which means unicorn in Greeκ) dedicated to AI, Stavros Vassos, the CEO and Co-Founder of helvia.ai discussed with Giannis Dionatos the company's origin, its clients, and the rapid evolution of artificial intelligence.  

Helvia.ai: helping businesses transform with AI 

Artificial intelligence (AI) has become ubiquitous in our daily lives, and its capabilities are evolving, allowing us to solve problems more efficiently and effectively. One such application of AI is in the development of chatbots, which are becoming increasingly popular in the business world.  

Founded in 2016, helvia.ai specializes in creating AI chatbots that equip companies with communication solutions. Helvia.ai’s no-code platform allows businesses to build automated chat within their systems, making communication easier for all parties involved.  

AI Chatbots: the future of communication   

AI chatbots are systems that offer dialogues, making communication easier for customers and employees alike. They enable communication, even in simple matters such as the location of a package that has been ordered, or even more complicated, step-by-step guidance. With a wide range of applications, AI chatbots are becoming increasingly popular in the business world.  

In recent years, chatbots have become popular in two main areas of business. The first is customer service, where chatbots help end-customers learn and solve their problems. The second is internal problem-solving, where chatbots help employees and partners with their work. Helvia.ai's platform is centered around making these solutions customizable to meet the specific needs of each organization.      

Helvia.ai's journey: from Greece to the US    

Starting a technology start-up in Greece may be challenging, but both co-founders had spent many years abroad and were familiar with the communication channels used in North America. This knowledge gave them an advantage in finding clients from the other side of the Atlantic.  

In 2017, helvia.ai managed to find large clients outside of Greece who trusted them and are still with them. Their success with big clients in the US shaped the way their platform works, making it easier to address the needs of larger organizations.     

Helvia.ai’s focus in Research & Development

Artificial intelligence (AI) has come a long way since its inception and is now playing a significant role in many aspects of our lives. In business, AI is being used to improve efficiency, reduce costs, and provide better customer service.

Toraksero.gr, an innovative online platform aiming to address the challenge of accessing concise, accurate information on political parties

In response to the wealth of data and biased sources available to the voters, helvia.ai developed a platform that incorporates a digital assistant powered by Large Language Models (LLMs), to act as an online debate. The platform is tailored to answer voters' questions and help them make well-informed decisions about the political party that most closely aligns with their values.

By leveraging artificial intelligence and natural language processing, the platform ensures an interactive and convenient way for users to research and compare the positions of political parties in Greece and the Netherlands. By providing brief answers derived from official programmes and accompanied by reliable sources, the platform acts as a trusted digital assistant. The open access system supports English, Greek and Dutch and has been deployed on two websites:

• Toraksero.gr for the recent Greek elections (June 2023), which attracted around 30 thousand user sessions
• nuweetikhet.nl for the Dutch elections (November 2023).

The importance of retrieving political information

People's abstaining from elections is a critical and constantly growing issue in democratic societies around the world. A significant proportion of the population avoids participating in elections due to a lack of information about political parties. The absence of a comparable tool for accessing and searching political programmes underlines the importance of retrieving political information. This is particularly true for the youth, who are unfamiliar with the political landscape, and for the busy working class, who do not have the time to thoroughly evaluate and make informed electoral choices.

Access to accurate and comprehensive political information is vital for voters to make properly informed decisions. However, information overload, biased sources and time constraints pose significant challenges for citizens seeking reliable political information. Participating in political debates and controversies often requires clarifying differing views and identifying information that is presided over and supported by official sources. This process can be time-consuming and overwhelming, especially for individuals with multiple responsibilities and limited time to research each political party's policy agendas.

As a result, many citizens may find it difficult to navigate and understand lengthy and complex political agendas, preventing their ability to form educated opinions and make reasoned voting decisions.

Empowering voters with the use of AI

Toraksero.gr was launched in June 2023 as a platform designed to simplify the search for political information and help citizens better understand political positions. The platform was created to address the time constraints and information overload that many citizens face when trying to navigate political agendas on topics like taxation, healthcare, and education. To solve this problem, toraksero.gr's expert team curated political agendas from various parties and made them easily accessible to users. Using artificial intelligence, specifically Chat-GPT, the site became a reliable resource that provided both short and detailed answers to users' queries. This saved time for busy citizens while also ensuring they had access to trustworthy information, allowing them to make well-informed decisions about their voting preferences.

The platform allows users to browse the political parties they are interested in and delve into their agendas. Using innovative artificial intelligence, the platform extracts relevant information from these programmes and generates answers to users' queries using exact words from the relevant parts of the programme. The platform promotes impartiality by providing sources of information, enabling users to access more relevant material directly from the official program. This interactive and transparent approach enables users to verify the answers provided and develop a comprehensive understanding of each party's position on specific issues.

The operational process

The platform's capabilities are based on an NLP system architecture that leverages the power of OpenAI's GPT-4. This architecture incorporates Retrieval-Augmented Generation with RAG to efficiently integrate custom data into large language models (LLMs) and build user confidence. Utilizing advanced natural language processing and machine learning tools, the platform has been meticulously built to understand user queries and provide accurate and relevant answers. During the development process, the AI model was trained on an extensive database of political data, policies and positions from various political parties, allowing it to learn patterns and connections within the data and produce informative, contextually relevant answers.

Considering the need for a wider application and to reach a wider audience beyond the Greek citizens, we decided to extend the support of the NLP system to the Dutch general elections scheduled for 23 November 2023. While maintaining the integrity of the presented NLP architecture, we hired another domain expert to curate the political agendas of the Dutch political parties. The new Dutch corpus includes 18 parties and was seamlessly integrated into a "Dutch" iteration of our existing architecture.

After a rebranding process to adapt the website content for navigation in Dutch (as well as English), we launched the system on the new website domain https://nuweetikhet.nl/ask?lang=en, which translates as "Now I know! 

Evaluating Toraksero.gr: metrics and user satisfaction

To assess the effectiveness of the Toraksero.gr tool, we used a combination of different methods to gather feedback, evaluate its success, accuracy, latency and design.

Initially, the toraksero.gr team conducted internal tests before the public release. Employees tested the site, asked questions and evaluated the accuracy and usability of the platform. Their feedback and observations played a key role in identifying potential issues or areas for improvement. Also we sought feedback from external individuals, including non-experts. Each user was given a unique URL and a specific access token, allowing up to specific access token with a limited number of requests. We received feedback from alpha and beta testers, which helped us identify bugs, etc.This process facilitated the identification of small bugs, refinement of the visual design of the system, and improved the  performance in total. Next, our team employed Facebook and Google ads to reach a wide audience and encourage user engagement with the tool. This approach facilitated interaction with the site and gathered valuable feedback from a wide range of users.

Thirdly, we integrated a 'contact us' section with a chatbot into the platform and encouraged users to provide feedback directly through this chat. This allowed for real-time communication with users and simplified the collection of feedback on the tool's performance, user experience and accuracy of information.

The team, last but not least,  used social media channels such as Facebook and LinkedIn to post about the site and invite users to share their thoughts. Comments and interactions on these platforms provided additional feedback on the tool's usability.

Now let's look at a more detailed evaluation of the platform:

• User Satisfaction: Comments collected through automated chat, comments from social media posts and direct user interactions were analyzed to assess user satisfaction with the performance of the platform and the quality of information provided. 

Here are some authentic and honest comments from users who have experienced the transforming power of toraksero.gr:

1. ‘’Congratulations, finally an official information source for citizens to vote consciously and responsibly.’’🙌
2. ‘’Truly wonderful work and extremely useful for citizens who want to be informed without having to search. Is this the end of (non-subjective and guided, simply reproducing statements without critically examining them) journalism? Hopefully, it is.’’ 🧠
3. ‘’Congrats guys ! What hit me is the following : Until now, political parties and their advisors had to invent new ways to impress and engage the voters. Billions are being spent globally on that! The media and the voters were all together intertwined in a very close relationship- who’s to win, who's to blame etc. Now, you’re bringing the new generation of critics : AI, so parties have to win the LLMs too.’’😃😃
4. ‘’Just wanted to take a moment to thank you for developing this utility’’ 👏

• Accuracy of answers: The ability of the tool to provide accurate and relevant answers to users' questions was also assessed. The answers were compared with the official source and assessed for consistency with the political programmes of the parties concerned.
• User engagement: Analyzing statistics such as the number of user queries and frequency of interaction allowed us to measure user engagement with the platform. This analysis provided valuable information on the effectiveness of the platform in terms of attracting and retaining users. Exceeding expectations, Toraksero received over 29,629 queries based on internal statistics, showing significant user interest. This engagement highlights the value of the platform for individuals seeking updates on the political landscape. 

Following the launch of the platform, we used "like/dislike" buttons to collect user feedback, receiving a remarkable 74% of positive comments (likes) and indicating high user satisfaction. Of the total queries, only 198 (4.4%) revealed instances in which LLM provided an incorrect answer. These included cases where GPT-4 answered incorrectly (selecting the wrong source document) or claimed not to know the answer, despite retrieving the correct source document via semantic search."

• Feedback: User feedback and recommendations, both through automated chat and social media comments, were reviewed to identify areas for improvement and gather recommendations to improve the tool's functionality and user experience.

Limitations

While toraksero.gr has proven to be extremely useful, certain limitations should be noted. Foremost among these concerns is the content curation process, which depends on the availability and accuracy of information provided by political parties. Gathering up-to-date and consistent information from all parties is a challenge due to different inputs, communication strategies and limited resources for distributing information. 

Since Natural Language Processing (NLP) systems are based on textual data, we faced limitations in including political parties without publicly available agendas. For the Greek elections, we excluded four smaller, newly formed political parties that had not uploaded content. However, we are committed to incorporating their agendas into the NLP system to enhance public awareness in future elections.

Conclusion and next steps 

In conclusion, toraksero.gr has proven to be an extremely valuable tool for voters, facilitating the discovery of political information and aiding in making well-informed decisions. Users have provided positive feedback ,along with recognition from the media, highlighting the significance of such tools in ensuring citizens access to information regarding politics. 

Toraksero.gr, as a generative AI tool, serves as an ideal model for developing similar platforms in various domains, bridging information gaps and empowering users in different fields of knowledge. Through utilizing conversational AI, we can foster a more informed and engaged society.
