AI-assisted legal research and analysis

The legal database for the age of AI

Case law, statutes and commentary are structured as a machine-readable knowledge graph for transparent legal research and reliable AI use.

The legal knowledge graph

Statutes, commentary, court decisions and their relationships form a growing legal knowledge network. Defined source paths reduce hallucinations and make results verifiable.

• Statutes are uniquely structured and connected to interpretations and evidence.
