Free Citation Checker — Verify References & DOIs
Free citation checker for a pasted reference list. See which entries look real or fake, and whether each DOI resolves, before you sign in.
How it works
- Paste a reference list, one citation per line. Keep any DOI you already have.
- Press Check. The first references are compared with Crossref, OpenAlex, Semantic Scholar, and PubMed records before any sign-in prompt.
- Read the table. Real means the core record matched. Review means the match is incomplete. Fake means the identifier conflicts with the record we found.
- Open a resolved DOI and read the paper before you cite it.
What we check
- Whether a DOI resolves to a publication record.
- Whether the title, year, and authors agree with that record.
- Whether an entry looks fabricated or only partly matched.
- We do not format a bibliography here, and we do not decide whether the paper supports your claim.

Need to find papers from a Chinese sentence?
This page checks a reference list you already pasted. To start from a Chinese sentence and look for real papers, use the existing 反查文献 page. That Chinese reverse literature search is unchanged.
