AI tools hallucinate references — real journal names, real authors, fabricated details. STARCheckIt cross-checks every citation against Crossref and PubMed in seconds.
The checker searches Crossref (by DOI first, then by title) and PubMed for each citation. It compares title, authors, year, journal, volume, and issue against the official database record — and flags anything that doesn't match.
