FreeUnited States

Free U.S. primary-law database covering 10,000,000+ court opinions — the U.S. Supreme Court, all federal circuit and district courts, and the appellate and supreme courts of all 50 states and D.C. — plus 60,000 current U.S. Code sections, over 1.9 million state-statute sections across all 50 states and D.C., 1,300+ U.S. treaties, and 8,000+ pattern jury instructions. Positions itself as a free alternative to Westlaw/Lexis for primary law specifically; it does not include secondary materials like treatises or practice guides. Its standout feature is GoodLaw, a citator built over a citation graph of about 100 million resolved opinion-to-opinion edges (190 million in-text citations) that flags whether a case has been overruled, vacated, or questioned — the kind of good-law check that distinguishes it from a pure full-text case search. A companion CiteCheck tool verifies one citation or a whole uploaded brief (up to 50 citations at once) against the corpus, flags unsupported or miscited authorities, and suggests corrected Bluebook form. Separate modules add administrative-law material beyond ordinary case law: IRS guidance (~59,000 authorities, each with its own good-law status), immigration decisions (~180,000 BIA/AAO/OCAHO authorities, plus a visa-bulletin lookup), and trademark records (3.2 million+ USPTO applications, ~64,000 TTAB proceedings, TMEP/TBMP). Tax Court, Board of Tax Appeals, and TTAB *opinions* specifically are already counted in the 10,000,000+ court-opinion figure above, not additional to it — only the administrative-authority and application records in these modules are extra. Web search requires no account or login. The REST API and MCP connectors (separate endpoints for caselaw, tax, trademark, and immigration) need a free API key. Caselaw and tax connectors are listed directly in Claude's and ChatGPT's own connector directories; trademark and immigration connect via a custom MCP URL or a Custom GPT Action. Also works with Cursor, Claude Code, and Perplexity. Everything — search, API, MCP, and CiteCheck — is free during the company's current rollout; bulk data licensing (full corpus, citation graph, embeddings) is offered separately for teams building their own products on top of it.
