Citation & bibliography generator
Paste a DOI, a plain reference (title, author, year), a single BibTeX/RIS entry — or a whole BibTeX/RIS file to format your entire bibliography at once. Everything comes back in every major style; single references are verified against CrossRef and OpenAlex and checked for retractions. Free to use.
Format a whole bibliography at once
Exported a .bib or .ris from Zotero, Mendeley, or EndNote? Paste the whole file and Folio formats every entry into a clean, alphabetized reference list — switch the style for all of them at once, then copy the list straight under your References heading. No re-keying, no per-reference clicking.
More than a formatter
Most citation generators just format text. This one verifies the reference exists — articles in CrossRef and OpenAlex, books in Open Library — and checks it for retractions, because a citation that points to a retracted paper is worse than no citation at all.
Supported styles
APA 7 · MLA 9 · Chicago 17 (author–date and notes-bibliography) · IEEE · Harvard · Vancouver. The reference is built from CrossRef metadata, so it's accurate and consistent — the same engine Folio uses when you cite as you write.
Cite as you write
In Folio, citations format and renumber themselves while you draft — across your whole library.
