Are your references real?

Paste a bibliography or drop a .bib, .bbl or PDF. Citelint checks every entry against Crossref, arXiv and Semantic Scholar, and flags the ones that can't be found or have the wrong details.

Drop a .bib, .bbl, .txt or PDF here, or choose a file PDFs are read in your browser and never uploaded.

Questions

Is my paper uploaded?

No. PDFs and files are read inside your browser. Only the text of each reference is sent to our lookup service, which searches public paper databases and keeps nothing.

What does “Not found” mean?

We couldn't find the work in Crossref, arXiv or Semantic Scholar. That often means the reference was invented, but it can also be a book, thesis, report, website or a very new paper. Please check those by hand. Citelint never decides that something is fake.

What does “Details differ” mean?

We found the paper, but something in your reference doesn't match the record: usually the year, the first author or the DOI. The record's details are shown so you can fix it.

Which citation styles work?

APA, MLA, Chicago, IEEE, Harvard, numbered lists, BibTeX and LaTeX .bbl files. Each reference should start on its own line or be separated by a blank line.

How do I get my license key?

After checkout, Polar emails your key. Click “Enter license key”, paste it, and Pro unlocks on this browser. Lost it? It's also in your Polar customer portal.
