Citeory — the theory behind citations
Citeory is a citation drafting and checking tool by ClearKey Solutions LLC. Paste a DOI, a URL, or a rough citation and get a correctly formatted reference plus its in-text citation — or paste a whole reference list and have every entry checked and scored. Every citation is produced by a deterministic, rule-based engine (not generated by AI) and verified online against Crossref, DataCite, OpenAlex, Semantic Scholar, Open Library, and Google Books.
