I'm building LEGAION — an operating system for law in which every piece of information is verifiable at its source. I combine legal practice with technology so that trust in legal AI stops being a claim and becomes something you can check.
At the intersection of law, AI and security
I'm the founder and CEO of Aidvocates, Inc. — a technology company building LEGAION, an operating system for legal work. For years I've been focused on one question: how to make technology render law faster, safer and genuinely trustworthy.
I work at the intersection of three worlds — law, artificial intelligence and data security. It's a rare combination, and it's at that intersection that the most interesting things emerge: tools that understand the specifics of legal work and harness the power of modern AI, yet make no compromise where confidentiality and precision are at stake.
I'm obsessed with a problem most AI companies ignore: language models can sound convincing and be wrong at the same time. In law such an error is costly — a reputation, a case, a client. That's why the team I lead builds technology in which every AI-generated result is checked against its source, in official legal databases. Because in law the point isn't to sound clever — it's to not be wrong.
I run the company with an engineering hub in Poland, in Katowice, and a company incorporated in Delaware (USA). I believe in building products that solve real problems for real people — and in doing it honestly, step by step, without cutting corners.
LEGAION is an Enterprise OS for legal work — from contract and case analysis to AI-assisted negotiation. What sets it apart isn't another language model, but a verification layer that confronts AI output with current, primary sources of law.
Verification at the source
It reaches live into public databases of legislation and case law, combining them with its own corpus of doctrine. Every claim leads back to a source you can open and check.
Discipline over flattery
A mode in which the system deliberately probes the weak points of your argument and simulates the opponent's strategy — instead of confirming what you want to hear.
Data sovereignty
A platform designed for European privacy and compliance requirements, with infrastructure kept in the EU and built around full client control over their data.

Where I spend my attention.
Verifiable AI
How to design AI systems for law so their output can be traced to a source — and how to make verifiability a standard rather than a premium feature.
Law & technology
Practical AI adoption in law firms and legal departments — without losing professional rigor, with the emphasis on real workflows, not demos.
Sovereignty & compliance
A European approach to data, privacy and the AI Act — as a product foundation, not an afterthought bolted on at the end.
Team building
Leading a team where lawyers and engineers speak one language, and building a culture where precision is a value, not a brake.
I talk about where AI in law deserves trust — and where it doesn't.
