Repertorium · Legal knowledge infrastructure for AI
For people, for applications and for AI agents. Case law, statutes, citations, amendment history and the links between Polish and European law.
Repertorium is a corpus of Polish and EU law prepared for AI models: 1,523,697 Polish law documents, 247,954 European Union law documents and 1,535,990 links between them. Every passage comes back with a locator, that is a document identifier and a character offset, and a citation that could not be resolved stays in the answer with a named reason.

Write to usCoverage
Repertorium does not just collect documents. It joins case law, statutes, citations, amendment history and sources into one knowledge model.

European Union law
Rounded scale. Constitutional Tribunal rulings run to 2015. Every result has a document identifier, and legislation also links to its source.
Separate corpus editions, outside the console: USA · Brazil
What makes it different
Source
Every result leads to a specific document, case number, date and source. You can check where the information came from.
A reference that could not be resolved stays in the answer with a named reason. It does not disappear to make the result look complete.

Relations
Repertorium links judgments to statutes, to other judgments and to European law.
The graph lets you move from one document to its wider context instead of reading each one on its own.
judgment → art. 415 Civil Code judgment → III CZP 41/12 statute → CELEX 32016R0679
Time
Repertorium knows the amendment history and can flag that a provision cited in a judgment was amended later.
That is a warning for the lawyer, not a conclusion drawn in their place.
judgment of 2011-03-17 cites: art. 415 Civil Code amendments_since: 3 status: check the basis
Lifespan
Repertorium lets you watch whether an argument is cited later, developed further, or fades out.
A citation count alone does not show that: a thousand references from twenty years ago and twenty from last year are two different stories.
It does not write opinions and it does not replace a lawyer. It gives people and AI the sources, relations and context needed to work with law.
A model can generate an answer. Repertorium is there to show what that answer stands on.
Four ways in
Search here, or plug Repertorium into the tool you already work in.
WWW, MCP, your own application.
Use the structured corpus of law for RAG, evaluation, fine-tuning or training systems of your own.
Build your own LegalTech product on the Repertorium data layer.
White label, your interface, your product.
Run the part of the corpus and infrastructure you need inside your own environment.
Access for machines
Repertorium has a remote MCP interface. It already works with Claude and can serve as a source of law for your own applications and AI agents.
No downloading the whole database and no local copy of millions of documents to maintain.
Paste it once. It asks Claude to keep client data out of queries sent to Repertorium and other legal databases.
When you use Repertorium or any other legal-database connector, ask only about legislation, case law and legal questions. Do not put first names, surnames, company names, personal ID numbers, tax or company register numbers, addresses, dates or amounts from the matter into the queries, and do not include case numbers of matters I handle (case numbers of published judgments are fine). Describe facts in general terms (a limited liability company, an employee, a commercial lease). When verifying citations, send only the list of citations, not the text of the document.
Where to paste it
CLAUDE.md file in your project folder, or ~/.claude/CLAUDE.md for all projects.The instruction is a request to the model, not a technical block. What we store and for how long: Where your data is.
Access
Check Repertorium right away.
Plug a source of law into your own tool or agent.
Use a corpus edition, white label, or an installation in your own infrastructure.
An account appears only when it is actually needed. The terms each of these routes runs on: Repertorium License.
In the ecosystem
Today PATRON reaches Polish and EU legal sources through its own connectors; connecting it to Repertorium is planned. Repertorium's infrastructure can also run inside other applications and environments.
Questions
The console on this page searches the full corpus and asks for nothing. An account comes in only with MCP access, corpus editions and local installation.
From official gazettes and public case law databases for each jurisdiction. Every document carries a source identifier, and the corpus is a snapshot of the law on a given day, not a live stream.
Training rights sit in a separate licence, because the scope of permitted use differs between jurisdictions. The terms are in the Repertorium License. Tell us what you are building and we will come back with scope.
A search engine finds the document. Repertorium shows its place in the law: links to statutes and other judgments, the amendment history of the legal basis, and whether a line of case law is still alive.
