AI tools invent case citations that look completely convincing. Paste any text, including raw output from an AI assistant, and we will check every citation in it against a real case-law database and link you to what we find.
Free, no signup, no limits beyond basic abuse protection. We never store what you paste. If you want the background on why this matters in Canadian practice, read our note on Zhang v Chen.
What we do
What we do not do
This tool is not legal advice, and it does not replace your own verification. You remain responsible for every authority you rely on.
It means the citation matched a decision in the case-law database we checked for that jurisdiction, and we link you to it so you can read it yourself. Every link comes from the database, never from us.
It means the citation did not match anything in the case-law database we checked. That is a strong signal to look closely, and it is not by itself proof that the case does not exist. A citation can be mistyped, unreported, or from a court the database does not cover. Always confirm before you rely on it.
The case-law database was temporarily unavailable when we asked it, so we did not get an answer. That is a problem at the database, not with your citation, and it is not a verdict of any kind. Wait a few minutes and run the check again.
No. This tool answers one question: does this citation resolve to a real decision in the database we checked. Whether a case has since been overturned, distinguished, or is otherwise no longer good law is a separate question, and we will not imply an answer we cannot back.
No. Your text is checked in memory and discarded. It is never written to a database, never written to a log, and never used to train anything. We record only counts, such as how many citations were checked, so we know the tool is being used.
Canada, the United States and the United Kingdom. More jurisdictions are coming. Where we cannot check, we say so plainly rather than guess.
Because it is the honest version of a demo. Verification is the part of Juris we most want lawyers to test before they trust anything else we say.
Juris verifies every citation, on every case, by default.
An AI you can check, with a link on every authority it gives you.
