Supra generates citations from any source and cite-checks entire briefs and law review articles — so you catch every citation error before you file, not after.
Marbury v. Madison, 5 U.S. (1 Cranch) 137, 177 (1803).
Whether you need one citation or a full cite-check of a 60-page brief, the process is the same.
Paste text, a URL, or upload a PDF or Word document — a single case or an entire brief.
Every citation is generated or checked against the Bluebook — including the id. and supra short forms that depend on citation order.
Get verified citations, a clear list of what needed fixing, and a ready-to-use Table of Authorities.
Built for litigators, brief writers, and law review editors.
PDF, image, URL, or pasted text in — a properly formatted Bluebook citation out.
Upload your draft and every citation gets checked — motions, briefs, and memos of any length.
Footnote-aware checking for journal work — including "supra note 12" references that point to the wrong footnote.
Short forms depend on what you cited before. Supra checks them in order, across the whole document.
Every document check produces a grouped, alphabetized Table of Authorities you can copy or export.
Every finding is clear and specific — what was wrong, what it should be, and why.
A citation tool you have to double-check is not worth using. Supra verifies every citation before it reaches you, so the work you file reflects the care you put into it.
