Certify every citation before you file.

What does citation certification check?

Every authority in your filing is resolved on three dimensions. Existence: the citation is matched exactly against live case-law, so a fabricated case is flagged before you sign — the primary anti-hallucination signal. Quotation accuracy: quoted passages are matched against the published opinion, catching misquotes and invented quotations. Good-law standing: overruled or superseded authority is flagged, sourced from your firm's citator (KeyCite or Shepard's) — we never guess good law.

A citation passes only when all three hold. The result is not a flag on a dashboard — it is a certificate: a signed, independently verifiable record of exactly what was checked and when.

Why is a certificate different from a flag?

Most citation tools flag suspected problems and produce nothing durable. When a judge's standing order asks what you did to verify your authorities, “our tool flagged nothing” is an assertion. A certificate is evidence: each result is signed with post-quantum cryptography and sealed to an RFC 6962 transparency log, so a court, opposing counsel, or your insurer can confirm the checks ran — without trusting us or you.

What it does not do

• It does not promise an AI that never hallucinates — it certifies which of your citations are real, accurately quoted, and good law.
• Its resolution is only as complete as the case-law corpus it can reach; coverage is recorded with every result, never hidden.
• It certifies process and results, not whether your legal argument is correct.

Frequently asked questions

How does RankShield catch fabricated citations?

Each citation is resolved against live case-law using an exact match — not just the case name. A citation that does not resolve to a real opinion is flagged as fabricated and the filing is held until it is corrected, so a hallucinated case never reaches the court. Correct Bluebook formatting is never treated as evidence a case exists, because AI-fabricated citations copy perfect format.

Does it check whether a case is still good law?

Yes, as the third dimension of certification — sourced from your firm's citator, such as KeyCite or Shepard's, and recorded with the certificate. RankShield never guesses good-law standing on its own: if no citator input is available, the result is marked incomplete rather than silently passed, so you always know which dimension was verified.

Can a court or opposing counsel verify the certificate?

Yes. Every certificate is signed with post-quantum cryptography (ML-DSA and SLH-DSA, NIST FIPS 204/205) and sealed to an RFC 6962 tamper-evident transparency log. Anyone can check the inclusion proof independently, which turns “we checked the citations” from a claim into evidence.
