Repertorium · Legal knowledge infrastructure for AI

Law connected.
Not just searched.

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: 1,492,530 Polish law documents, 236,944 European Union law documents and 1,443,748 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.

What the corpus holds.
And how it connects.

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

What makes it different

A search engine finds the document.
Repertorium shows its place in the law.

Source

A document always has an origin.

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

Law is a network.

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

Law changes.

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.

Lifespan

A judgment does not end on the day it is published.

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.

Repertorium is not a legal chatbot.

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

One infrastructure. Four ways to use it.

Use it.

Search here, or plug Repertorium into the tool you already work in.

WWW, MCP, your own application.

Train with it.

Use the structured corpus of law for RAG, evaluation, fine-tuning or training systems of your own.

Brand it.

Build your own LegalTech product on the Repertorium data layer.

White label, your interface, your product.

Own it.

Run the part of the corpus and infrastructure you need inside your own environment.

Access for machines

Law available to agents.

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.

Data

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

Repertorium stands on its own.
It can power your system.

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

Before you ask

Really no account?

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.

Where does the data come from?

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.

Can I train a model on this corpus?

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.

How is this different from an ordinary case law search?

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.

Your AI does not need another model.
It needs better access to the law.
