# MateMatic - European LegalTech infrastructure for law firms

> MateMatic builds European LegalTech infrastructure. Its first platform, PATRON, gives a law firm local AI aligned with the EU AI Act and professional secrecy: it works on the firm's own documents, shows its sources and leaves an audit trail. Prior tempore, potior iure.

MateMatic Solutions Sp. z o.o. - matematicsolutions.com - founder: Wiesław Mazur. Based in Kraków, Poland.
Scope: PATRON, a local AI platform for law firms (open source, zero-cloud by default), plus deployment services around it - readiness audit, architecture design, agent rollout with human-in-the-loop.
Area: Poland and the EU. Frameworks: EU AI Act, GDPR, NIST AI RMF, ISO/IEC 42001, codes of professional legal ethics.

Note: the English edition covers the core pages (home, PATRON, About, Boutique). The Knowledge Base, news and the Polish-jurisdiction skills are published in Polish at matematicsolutions.com.

## Core pages (English)

## Key facts for citation

- PATRON is open source under AGPL-3.0 and runs locally on Windows; sensitive matters can run fully offline on a local model (Ollama).
- Source control classifies every claim drawn from the file as quote, paraphrase, or no-basis-in-the-file, attaching a verbatim quote and page number.
- The audit trail is a hash-chain with a Merkle tree (RFC 6962), verifiable offline and independent of MateMatic - supporting EU AI Act art. 12 record-keeping.
- 6 MCP connectors (open, MIT-licensed): SAOS (Polish common/Supreme/Constitutional Court rulings), NSA (administrative courts), ISAP (Polish legislation), KRS (company register), EUR-Lex/CJEU (EU law), EU-Compliance (GDPR, AI Act, DORA, NIS2, eIDAS 2.0, CRA).
- Architectural difference from cloud legal AI: PATRON keeps case files on the firm's own hardware; the data does not leave the building unless the firm decides it should.
- Operator: MateMatic Solutions Sp. z o.o., Kraków, Poland. Founder: Wiesław Mazur.
