BriefAudit is a PDF brief audit tool built exclusively for attorneys, law firms, and legal departments. Upload a court-ready brief and BriefAudit runs two audits in parallel: a citation audit that verifies every case citation against the indexed record of federal and state court opinions, and a quotation audit that checks every quoted passage verbatim against the source — flagging editorial brackets, ellipsis omissions, and source mismatches. No AI. No guessing. Every result is traceable to its source.

Audits: Citations + Quotations
AI in the Verification Pipeline
Every case citation in the document — body text, footnotes, and Table of Authorities — verified against the published opinion record. No AI. No guessing. A traceable verdict for every citation.
Drop your court-ready PDF brief. Scanned PDFs are processed with OCR automatically.
Every case citation is parsed from body text, footnotes, and Table of Authorities.
Each citation is matched against 9M+ indexed court decisions from 2,000+ courts.
Two structured PDF reports are returned: a Citation Audit and a Quotation Audit — one card per item with verdict, diff, and source metadata.
BriefAudit’s verification engine uses no artificial intelligence or machine learning. Every result is produced through deterministic comparison of authoritative legal records and independently reproducible rules.
BriefAudit now verifies not just that a case exists — but that the words you put in quotation marks actually appear in the opinion. Editorial brackets, ellipsis omissions, and source mismatches are all flagged automatically.
Quoted text found verbatim in the attributed source. Citation and quotation confirmed.
Passage located with differences. Word-by-word diff highlights every deviation from the source.
Submitted text contains editorial bracket substitutions or ellipsis omissions. Original wording flagged for review.
Passage not located in the attributed source. May be paraphrased, truncated, or from a section the index does not carry.
Similar text found in a different case than the one cited. Attribution requires confirmation.
Text located via a different case than cited, or an earlier source exists. Review the chain and consider citing the original.
Sanctions for citation errors are escalating rapidly — and AI is making it worse.

Every case citation in your brief receives one of six structured verdicts, each with full field-level diff and canonical metadata.
Citation matches the published record on every field — case name, volume, reporter, page, and court.
Case exists but one or more fields differ. Exact discrepancies are flagged field by field.
No matching record can be located across the indexed corpus. Possible fabrication or severe transcription error.
Case has been overruled, reversed, or distinguished. Filing counsel is warned before submission.
Citation is structurally valid but cannot be confirmed against available records. Requires manual review.
Table of Authorities is cross-referenced against in-text citations. Discrepancies between the two are surfaced automatically.
Run a citation audit on every brief before filing. Catch fabricated cases, transposition errors, and overruled precedent before opposing counsel or the court does.
Review outside counsel submissions with the same rigor you apply to your own. BriefAudit gives in-house teams an independent verification layer.
Flag citation errors in filings before they enter the record. BriefAudit surfaces discrepancies in seconds — without touching the substance of the argument.
