- Format citations in 10,000+ CSL styles (Vancouver, APA, AMA, IEEE, CSE, and any CSL style ID)
- Export bibliographies to BibTeX, RIS, CSL JSON, EndNote, RefWorks, MEDLINE, Zotero RDF, CSV, or plain text

- Check open access status and the best legal copy (Unpaywall)
- Verify that a claimed citation actually matches the paper at its identifier — catching the AI-driven "real DOI + invented title" fabrication pattern
