Frequently Asked Questions

What bibliography formats are supported?

BibTeX, BibLaTeX, RIS, EndNote XML, and CSL-JSON. We can also import directly from Zotero and Mendeley.

How does auto-fix work?

We look up entries by DOI, title, or author in academic databases and suggest the correct metadata.

Will this change my citation keys?

Only if you want it to. We can standardize keys, but existing document citations update automatically.

Can I use this with Overleaf projects?

Yes, import your .bib file, fix errors, and export the corrected version back to Overleaf.
