FreeInformation, not adviceCite the authority, or abstain

Check your legal AI citations — before a court does.

Paste a brief, memo, or AI-drafted draft from any tool. TrustAI extracts every citation and checks whether each case citation actually exists in an authoritative source; statutory citations are surfaced for your review. Each verdict shows its work. Where a citation can’t be verified, it says “check manually” — it never accuses a real case of being fake.

Why this exists. Independent research found leading legal-AI tools hallucinate citations at material rates, and attorneys have been sanctioned for filing AI-fabricated cases — the court in Mata v. Avianca, 678 F. Supp. 3d 443 (S.D.N.Y. 2023) imposed a $5,000 sanction over six fabricated opinions. This is the tool that helps you catch that before you file.

Verdicts

Your per-citation verdicts will appear here. Each one is one click from its proof of work — the source queried and exactly what came back.

How this works — and what it never claims

The tool surfaces information; your licensed attorney judges fit. It tells you a citation exists, could not be found, or could not be verified — it never opines on whether an authority supports your argument, and it never calls a real case fake. Coverage is bounded by the source and stated plainly.

VERIFIED — an authoritative record matches the citation.
NOT FOUND — the citation is in a well-covered reporter and no matching record exists. Verify before filing.
UNVERIFIABLE — the citation is outside confident coverage or the source couldn’t be reached. Check it manually — this is not an accusation that it is fake.

Sources checked against

Case citations are checked against CourtListener (Free Law Project), which covers roughly 99% of precedential U.S. case law. It has no citator, so a citation outside confident coverage is marked UNVERIFIABLE, never falsely flagged. Statutory citations are surfaced but not auto-verified against a code here.

TrustAI is not a law firm and does not provide legal advice. This tool verifies whether citations exist and shows its work; it does not tell you whether an authority supports your argument or what action to take. Those judgments belong to a licensed attorney. What TrustAI does, and never does →
