AI that knows
what it doesn't know.

A tool, not an oracle.

We build LegalTech that hides neither its sources nor its limits. PATRON, our first platform, works on the firm's own documents, shows where it knows the answer from, and lets you retrace the path to it.

PATRON runs on your hardware. Case files don't leave the firm without your decision.
First product

The first product already works.

Good legal technology doesn't replace judgment. It provides a basis, shows its limits and lets you retrace the path to the answer. That's how we built PATRON.

PATRON is a local AI platform for lawyers. It connects the firm's case files with Polish and EU legal sources - all locally, on your own hardware. Open source, an audit trail, the decision staying with the lawyer.

01 - How PATRON works

PATRON doesn't start with an answer.
It starts with the basis.

Step 01

It reads documents and sources

It ingests the firm's case files and verified legal sources. It finds the relevant passages and stays with them. The answer doesn't drift away from the document.

Step 02

It shows how it knows

Every answer is tied to a source. PATRON tells a quote, a paraphrase and "no basis in the documents" apart. It doesn't mask uncertainty behind fluent language.

Step 03

It leaves the decision to the lawyer

It records the path to the answer, the sources used and the operations run. You can check, retrace and challenge the result before it reaches a filing or a client.

02 - The thesis

Built in Europe.
Runs on your hardware.

Most legal AI sends the case file to someone else's cloud. We took the opposite path - the data stays where the duty of confidentiality lives, and the compliance burden becomes an architecture, not a promise.

Local-first

The data doesn't leave the building

PATRON runs on the lawyer's own machine. Sensitive matters can run on a local model and stay fully offline. Confidentiality stops being a policy you trust and becomes a property of where the work happens.

Compound regime

AI Act and GDPR, by design

A law firm running AI answers to several regimes at once - GDPR, the EU AI Act (high-risk), professional secrecy. We design for transparency, human oversight and an audit trail from day one, not as an afterthought.

Open source

Inspectable, not a black box

PATRON is open source (AGPL-3.0). You can read how it grounds an answer, verify the audit trail offline, and own the engine rather than rent it. The intelligence is replaceable; the structure around it is yours.
