Check your references before your professor does.

Paste your reference list and we look up each entry, showing what matches, what's off, and what we couldn't find. Or build a single citation from a title, DOI, ISBN or link.

Free. No signup. Nothing you paste is stored.

Best format: Author. (Year). Title.

Up to 25 references. Numbering and bullets are fine. We don't store what you paste.

Checked against Crossref, OpenAlex, Open Library, Google Books, DataCite and PubMed, with retraction data from Retraction Watch.

What you get back

Every reference gets a verdict, the record we matched it to, and a corrected citation in the style you picked. Errors are marked right in the reference, so you can see what to fix.

  1. Verified

    LeCun, Y., Bengio, Y., & Hinton, G. (2015). Deep learning. Nature, 521(7553), 436–444.

    Matches the published record in Nature. doi.org/10.1038/nature14539

  2. Mismatch

    Kahneman, D., & Tversky, A. (19811979). Prospect theory: An analysis of decision under risk. Econometrica, 47(2), 263–291.

    The year in the record is 1979. Everything else matches.

  3. RetractedMatches record

    Wakefield, A. J., Murch, S. H., Anthony, A., et al. (1998). Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children. The Lancet, 351(9103), 637–641.

    This paper exists, but The Lancet retracted it in 2010. Don't cite it as evidence.

  4. Couldn't verify

    Martínez, L. (2020). Memoria y territorio en la poesía andina [Tesis de maestría]. Universidad Nacional.

    No match found. This looks like a thesis, and most theses aren't in the databases we search. Try your library's catalog. This doesn't mean the source is made up.

How PaperCitation is different

Retraction warnings
If a paper you cite has been retracted, we flag it clearly. Most checkers don't tell you.
Honest about what it can't find
Books, theses, non-English titles and reports are often missing from scholarly databases. We say "couldn't verify" and explain why, instead of calling your source made up.
Evidence, not an AI's opinion
Verdicts come from comparing your reference with the published record, and we show you that record. AI is only used to read messy formatting.
Private and actually free
No account, no paywall on exports, and we never save the references you paste. Read the privacy policy.
