We build European LegalTech infrastructure: the sources, tools and procedures that let AI in legal work rest on what can be checked.
MateMatic Solutions Sp. z o.o., based in Kraków, Poland, combines legal experience with systems architecture. We treat a language model as a tool that has to show what its answer rests on.

Writing an article or a round-up? The press kit has a description ready to paste, technical facts and screenshots.
Four layers of one infrastructure. Each works on its own, so you can start with the one you need.
Repertorium
Legal knowledge infrastructure. A corpus of Polish and EU law with the links between documents, amendment history and the provenance of every passage. Used by people, applications and AI agents. Open Repertorium
PATRON
The lawyer's workspace. A local application for working on case files, with source verification, an audit trail and the decision left with a person. Open source. Meet PATRON
Boutique
Extensions: MCP connectors to public sources of law, and skills, meaning ready-made procedures for an AI assistant. You install only what you need. See the catalogue
Implementation
Audits, architecture, standards and training. First we check where AI makes sense in a firm and what risk it carries, then we design a specific process. Write to us

LinkedInA tool, not an oracle. Four working rules follow from that.
Source before answer
A quotation comes back with its document identifier and place in the text, and an answer without a basis gets a label instead of sounding certain.
A person decides
The tool points, checks and warns. The conclusion and the signature stay with the lawyer.
Verifiable without us
PATRON's code is open, the audit trail verifies offline, and where your data sits is set out on a separate page.
Local first
PATRON runs on the firm's own hardware, and Repertorium also comes as a local package. In PATRON it is the firm, not us, that switches on a cloud model.
