Is that citation real?
Your AI sounds just as confident when it invents a case. Chavis checks every citation against real public court records — in seconds, inside Claude, ChatGPT, or whatever you use.
What it tells you
Real or not. The citation either resolves to an actual published opinion — name, court, date, parallel cites, link — or it doesn't. No "I believe."
What later courts said. It reads the opinions that cite the case and quotes any passage saying it was overruled, disapproved, abrogated, or superseded — and tells the difference between "was overruled" and "overruled something else."
Statutes, from the source. California code sections pulled straight from the Legislature's official text, with amendment history.
Inside your AI. Paste one link into Claude or ChatGPT and the tools appear there — verify a cite mid-draft, or check a whole brief before it goes out.
Honest about what it is
Chavis runs on public court data (the Free Law Project's CourtListener) and official legislative text. It is not Westlaw, Lexis, KeyCite, or Shepard's, and it doesn't pretend to be. It catches the cite that doesn't exist and surfaces the later opinion that says "overruled" — then it shows you the passage so you decide. Think seatbelt, not autopilot.
Built by a practicing California litigator who got tired of wondering.
