Check every citation before you file.

Drop in a brief. LegalCite checks every case citation against real court records and flags the ones that don't exist or don't match — then prints a verification report for your file. Built for lawyers who draft with AI. It never invents a case.

The problem

Generative AI invents case law. It produces confident, properly-formatted citations — Smith v. Jones, 999 U.S. 9999 — for cases that were never decided. Courts have now confronted AI-fabricated authority in over 1,600 documented decisions, with new cases added daily — and the lawyers involved are sanctioned by name, in public. Checking every cite by hand doesn't scale across an AI drafting workflow. Skipping the check is how you end up in that database.

The fix

LegalCite reads the text, detects every citation, and resolves each against CourtListener (public court records). For each one it tells you: real (the case exists and the name matches, with a link to the actual opinion), not-found (no such case — likely fabricated), or name-mismatch (the reporter slot is real but the case name in the draft is wrong — the error that gets people sanctioned). No fabrication path — an unresolved cite is reported as not-found, never invented.

Brief Check — upload, verify, print the report

Upload a DOCX or PDF. Your document never leaves your browser — text is extracted locally, checked against court records, and you get a color-coded report of every citation with links to the real opinions. Print it to PDF and drop it in the file: dated proof you verified every cite before filing.

Use it as an MCP server

Any MCP-compatible agent (Claude, Cursor, Codex…) can call the verify_citations tool before relying on AI-drafted authority:

// MCP tool
verify_citations({ text: "...the holding in Smith v. Jones, 999 U.S. 9999..." })
// → each cite resolved against real court records: real / not-found / mismatch

Or hit the REST API directly:

GET https://www.legalcite.io/api/verify?text=Roe+v.+Wade,+410+U.S.+113

Not legal advice. LegalCite verifies whether a citation exists in public court records (CourtListener) and returns its metadata. It does not assess legal correctness, holdings, or good-law status.
