Grounded legal research,
with the citation built in.

- Citation & effective date on every provision
- One click to the official source

Full-text, trigram, and vector embeddings fused with Reciprocal Rank Fusion — type a citation number or describe the issue and the on-point provision surfaces either way.

- Ranked, cited results — not ten blue links
04 — Under the hood
Why the answers hold up.
Grounded retrieval
Answers are built from the retrieved, human-reviewed text — not the model's memory. No support, no answer.
Citation verification
A deterministic check confirms every quote and citation against the source before the answer reaches you.
Currency tracking
Amendments and editions over time, with flags when a provision or holding has been superseded or overruled.
Real citations
Citation, effective date, and enacting session law on every provision, linked to the official publication.
MCP & API
Use it in the browser, or wire the corpus into Claude Desktop and your own tools over a production MCP endpoint.
