View in Claude directory

Vaquill AI gives Claude direct access to United States primary law, ingested from official government sources and cited back to them.

COVERAGE. The United States Code, the Code of Federal Regulations, all 50 state statutory codes plus DC and Puerto Rico, state administrative regulations, federal and state court rules, federal and state constitutions, federal agency guidance from 51 named sources, agency adjudications, the Statutes at Large, and the Federal Register. More than 5.4 million sections, including repealed and historical provisions kept with their status.

WHAT YOU CAN DO. Search every corpus at once, or scope to one jurisdiction, body of law or status. Resolve a citation such as 42 U.S.C. 1983 to the exact provision it names. Read a section's operative text, or read it as it stood on a past date and see what changed. Find the sections that cite a provision, the terms it defines, its neighbors and the equivalent rule in other states. Look up state session laws as enacted.

SOURCES. Every result carries its official source URL and the publisher's own status for that section. The good-law signal reports what the publisher records about repeal or supersession. It is not a judicial-validity check, and where currency cannot be vouched for it says unknown.

READ ONLY. This connector only reads. It changes nothing in your Vaquill AI account or anywhere else.

Reads United States primary law from Vaquill AI's own corpus: statutes, regulations, court rules, constitutions, agency guidance and adjudications, with the official government source URL on every result. It reads no files, no messages and no documents of yours, and it sends nothing to any third party. Sign-in identifies your Vaquill AI account so usage bills to your own credit balance. The only things it can change are your own law-change alert subscriptions: creating, updating, testing and deleting a watch inside your Vaquill AI account. Nothing is written outside that account.
