A correctly formatted DOI is not a real DOI. Verify every citation in your reference list
against CrossRef, OpenAlex and Semantic Scholar.
AI tools generate DOIs that follow the correct format — 10.XXXX/XXXXXXX —
but lead nowhere, resolve to a completely different paper, or do not exist in any registry.
Visual inspection cannot distinguish a real DOI from a fabricated one.
Both look identical until you query the database.
AiCitationChecker checks each DOI directly against CrossRef — the primary global DOI registry — and cross-references the resolved metadata against OpenAlex and Semantic Scholar. If the DOI does not resolve, or resolves to a paper that does not match the citation, it is flagged with a specific error.
This matters beyond obvious fakes. Partial hallucinations are harder to catch manually: a DOI that resolves correctly but with the wrong authors, or to a real paper with a different title — these pass a quick URL check but fail a metadata check. AiCitationChecker runs both.
Correctly formatted, never registered. The AI generated the number pattern without checking the registry. No record in CrossRef or any database.
The DOI is real — but it belongs to a completely different publication. Different title, different authors, different year. The citation is fabricated despite the DOI being valid.
The paper exists. The authors listed are wrong, or the journal title is modified, or the year is off. Verifiable against CrossRef in one query.
Used AI to help write or find references? Verify every DOI before submission. A fake DOI found during review is binary evidence — no argument is possible.
Run the DOI list before writing your review. Invalid or mismatched DOIs become documented findings, not suspicions.
Screen submitted manuscripts at intake. Desk-reject papers with fabricated DOIs before they consume reviewer resources.
Copy all citations — with or without DOIs. Any format accepted. AiCitationChecker extracts DOIs automatically and also searches by title for references without one.
Each DOI is queried against CrossRef. Resolved metadata is cross-referenced against OpenAlex and Semantic Scholar. Every mismatch is flagged with a specific reason.
See exactly which citations passed, which failed, and why. For every reference confirmed real, the output is reformatted from CrossRef metadata — the authoritative record. Choose a citation style (APA, IEEE, Chicago, Harvard, Vancouver, MDPI) and download the clean list as a Word document.
