Check every citation.

Drop in a brief, memo, or opinion letter — Word doc, PDF, or pasted text. Every citation is checked against the primary source — case law via CourtListener, the U.S. Code, the CFR and Treasury Regulations, and IRS Revenue Rulings and Procedures. Fabricated citations get flagged before a judge finds them.

Ephemeral by design: files are read in your browser and never uploaded, and the text is parsed in memory and discarded — never stored, never logged, never used for training. Only the citations themselves are looked up.
