Pavol Hejny đź–Š AI That Actually Helps

ChatGPT, Claude, Gemini, GitHub Copilot, Cursor, RAG, MCP, Agents, Books… 🤯

Are you trying to figure out where AI really makes sense in your company and where it is just expensive buzzword theater?

I have been using AI in practice since its early waves. We have already gone through blind alleys, hype experiments,
and misplaced trust in tools that cost companies time, money, and confidence.

I help companies make AI useful in real operations:
from AI coding and agent workflows to quality checks, context management, rules, data safety, and change management.

I do not focus only on what the model can do. I focus on how to plug it into a company, team, and product
so it still creates value six months later, not only in the first demo.

If you want to use AI fully without unnecessary hype, I can help.

Who I am?

I'm Pavol, a developer with more than 15 years of day–to–day experience building software.

Today I focus mainly on AI: I help companies launch their own AI, design agent workflows, and introduce processes for safe and effective AI coding.

I am the Founder & CTO of Promptbook, an ecosystem for persistent AI agents that work with goals, knowledge, rules, and company context instead of one–off chats.

In practice, I work on topics such as AI vendor lock–in, data protection, output reliability, rulesets, knowledge bases, permission management, and automation of routine work across a company.

In software development, I push AI coding with process: PRDs, Git, automated tests, CI/CD, code review, backlog automation, and measuring whether human time and agent tokens are actually being used well.

Alongside Promptbook, I am a member of the Ainautes consulting group and I regularly speak about AI in organizations, vibe–coding, and the gap between hype and production reality.

Before this AI wave, I created the virtual whiteboard Collboard and the H-edu digital textbooks, worked on scientific projects for the Czech Ornithological Society, and built many other products from prototype to production.

Many of my projects are open source and available on my GitHub.

How can I help you?

AI is not one tool and not one workshop. It is an ongoing process that needs
the right use cases, rules, context, and quality control.

I've known Pavol for 6 years. Especially from hackathons and other innovation projects. If you are with his team, you can bet he'll be in the top three. And you would have right! Pavol is an innovator who knows the latest technologies and can find quick solutions to challenges in industry, education and urban development. He's capable of making a difference within 24 hours. He is one of the top 10 people in the country for rapid prototyping of applications.

Pavol built a prototype of our H-edu app so that we could get immediate investment. He then designed the architecture of the system and the use of the technology, which proved to be the right choice for our purposes. In the early days of covid-19, responded very well to the teaching needs of the teachers and in record time created exactly the solution that thousands of teachers have since used.

Pavol is an absolute beast when it comes to creating digital products. I've seen him – literally overnight – create an integrated chatbot that won us the 1st place at Startup Weekend Prague. He learns any topic or technology quickly and builds even faster, with exceptional usability. I'd recommend Pavol to everyone who wants to see real life results in a manageable time frame. Plus he's really considerate, kind and a pleasure to work with.
