What FixTools AI Citation Generator is
FixTools AI Citation Generator is a web tool that formats citations from a DOI, URL, ISBN, or raw citation. A single result can include APA 7, MLA 9, Chicago notes-and-bibliography, Harvard, IEEE, and BibTeX, alongside a summary of author, year, title, and publisher for checking. It marks fields it cannot identify as [unknown] and adds a note when source identification is uncertain. The citation workflow sends input to Anthropic Claude for metadata extraction or recall and formatting. FixTools says it does not store citation inputs or outputs, though the input is sent to Claude. It does not currently fetch live metadata from CrossRef or DOI.org, so details for newly published papers may be incomplete. The free plan allows up to 600 characters per run; paid input limits are 5,000 characters, and each run uses one credit. Pricing includes $2.99, paid once for Day Pass, $9.99 a month for Monthly, and $19.99 a month for Pro. Generated BibTeX imports into Overleaf, JabRef, Zotero with BetterBibTeX, and standard LaTeX workflows.
