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.
  • Commentary translates abstract rules into concepts and traceable arguments.
  • Court decisions provide reliable sources and are linked to the provisions they apply.
