CiteStamp

AI-invented citations caught. Retractions watched daily. Your work on an open graph, no gatekeeper. Free, in your browser.

An AI just handed you a citation for a paper that was never written. Would you catch it before a reviewer does? Get your work CiteStamped before you hit submit! CiteStamp checks whether the references in your work actually exist — and whether the real ones have quietly been retracted. It runs on the pages where you read papers and inside the Overleaf editor where you write them, and it never uploads your work to do it. WHAT IT CATCHES * References that resolve to nothing — no such paper in Crossref, DataCite, or OpenAlex. The classic tell of an AI-invented citation. * A DOI that points to a different paper than the one you cited. Right number, wrong work. * Papers a publisher has marked retracted, withdrawn, or flagged with an expression of concern — including ones pulled long after you cited them. WHERE IT WORKS * On any paper page — arXiv, Nature, PubMed, SSRN, a bare DOI link, and two dozen more scholarly sites — CiteStamp reads the identifier already on the page and puts that paper's citation record on your toolbar: who has cited it, split into human-signed claims and machine-inferred ones, never mashed into a single "score." * In Overleaf — paste your .bib for a full sweep, or let Pro check every reference the moment you type or paste it, no button to press. A made-up \cite{} lights up before it ever reaches a reviewer. * Everywhere else you work — the same engine runs free on citestamp.com, in the Microsoft Word task pane and the Google Docs sidebar (the check plus literature search; Pro writes the citation at your cursor and the reference list into your document), and in the Zotero item pane. AI agents get it over MCP. One check, every surface you write in. IT KEEPS WATCHING Papers get retracted after you cite them. Add any paper to your watchlist and CiteStamp re-checks it every day against publisher notices — and with Pro, everything you cite by DOI is added for you. The study you leaned on in spring gets pulled in the fall, and it shows up on your toolbar. You never have to remember to look. YOUR OWN WORK, ON THE OPEN RECORD No institution, no subscription, no gatekeeper. CiteStamp is built on an open citation graph that is CC0 and owned by no publisher. Claim your papers with your ORCID iD and sign your own claims onto a public, append-only log, and your work gets its own citation record and graph view — a permanent, accountable place on the scholarly record, whether or not you are affiliated with anyone. Signing is free, and so is looking. Independent researchers were the first people this was built for. NOTHING LEAVES YOUR BROWSER No upload. No account. No tracking. Your bibliography is parsed and checked right on your machine; reference lookups go straight to the public registries. The only thing about your work that ever reaches CiteStamp is a paper's public identifier, to pull its public citation record. FREE — AND IT STAYS FREE The check is unlimited and needs no account: on every paper page, and inside Word, Google Docs, Overleaf, and Zotero. So is the watchlist. Pro ($35/year) adds what runs while you write — continuous checking in Overleaf, one-click citation insertion in Word, Docs, and Overleaf, and automatic watchlist enrolment of everything you cite by DOI. Free and Pro catch the same problems; Pro just does it without being asked. Built for researchers — independent or affiliated — students, journal editors, and anyone who lets an AI draft anywhere near their bibliography.
