Citation Verifier
A citation checker for every reference: existence, accuracy, retraction or overruling, and misquotation, with a keep, fix or drop verdict and a corrected reference.
Built for lawyers, researchers and editors who need a citation checker before filing or publishing.
Why this work is hard
Lawyers, researchers and editors checking references before filing or publishing spend hours on this by hand: finding the right sources, reading them, checking them against each other and writing up what matters. The work is repetitive, it is easy to miss something, and nobody can show where a claim came from.
Citation Verifier does that work as a GREP AI agent. It takes a whole list in one run and returns one row per item. Every run delivers a sourced report, with every claim linked to its source.

FAQ
What does Citation Verifier need to run?
Citation Verifier needs citations or document text to check; citation style or jurisdiction (optional) and cutoff date for good-law/retraction status (optional) are optional.

It takes a whole list in one run and returns one row per item.
What does Citation Verifier deliver?
Every run delivers a sourced report, with every claim linked to its source.
Can I change what Citation Verifier does?
Yes. Every GREP AI agent can be cloned into your workspace, where you can edit its instructions, add your own sources and files, and change its schedule.
What does the citation checker verify?
That each cited work exists, that names, title, volume, page or pin cite, year and court or journal are correct, whether it has been retracted, corrected, overruled, reversed, superseded or repealed, and whether the quote or proposition appears in the source.
Which sources does it use?
For law, official court sites, CourtListener, Google Scholar case law, govinfo and legislature sites. For scholarship, DOI resolvers, Crossref, PubMed, publisher pages, the Retraction Watch database and journal correction notices.
What if a citation cannot be found?
It is marked unverified rather than fabricated, with a note on what was searched. The checker never invents a citation or fills a gap by guessing, and notes when a paywall limits the check.
