Paste a reference list, or drop a .bib, .txt, or .pdf. Every reference is checked against CrossRef and OpenAlex, live, right in your browser, nothing is uploaded to a server.
Tip: from a PDF we auto-extract the reference section, review and edit the list before running.
CiteWarden runs entirely client-side against the public CrossRef and OpenAlex APIs. "Verified" confirms a matching record exists with consistent metadata; it does not judge whether a citation supports the claim it's attached to. Coverage is scholarly literature indexed in those databases, books, case law, and grey literature may show as "Not found."
