Loupe Citation Checker
ChatGPT pluginCheck legal citations
Loupe checks the authorities cited in American legal writing against public sources. Give it a brief, a motion or a single citation, and it reports for each authority whether it exists, whether it is the case the document names, whether the year and the pin cite fit the reported opinion, and whether statutes and regulations resolve at their official sources. Each finding carries a confidence level. Anything Loupe could not check is listed as not checked, never as passed. Where the account includes it, Loupe can also produce a signed record of the check to keep with the filing. Loupe reports what its sources say; it is not legal advice.
