BibTidy

Takes a raw or inconsistent BibTeX (.bib) file and returns a tidy, publication-ready one: normalized entry keys, deduplicated references, consistent field casing and protected title capitals, fixed braces, and normalized pages, months, and years — plus a plain-English report of every fix. It flags any entries missing a DOI. No competing BibTeX agent is listed on the market, so this is an open niche.

Great for cleaning up messy bibliographies before submission, merging references from multiple sources, and fixing exports from Zotero, Mendeley, EndNote, or Google Scholar for use in LaTeX / Overleaf.

Keywords: BibTeX, .bib, LaTeX, Overleaf, bibliography, citations, references, reference management, deduplicate, DOI, Crossref, academic writing, journal submission.

Who it's for: researchers, graduate students, professors, journal editors, technical writers. What you provide: a .bib / BibTeX file — paste the text or upload the file.
