CitePlain vs Yomu AI Citation Generator

CitePlain creates citations and bibliographies from web pages, journal articles, books, tweets, YouTube videos, and podcasts. It accepts URLs, DOIs, or ISBNs, and uses publisher citation and Open Graph metadata, with Crossref lookup for DOIs and Open Library for ISBNs. The free plan includes APA 7, MLA 9, Chicago 17, Vancouver, CSE, and BibTeX, plus a bibliography builder for up to 50 sources per batch. The extension for Chrome, Edge, and Firefox can read metadata from the active tab and provide BibTeX with a stable cite key for Overleaf or Zotero. Pro adds 24 specialised styles, batch URL import for up to 50 sources, and cloud storage synced across the web app and extension. Free-tier references stay in browser local storage. Pro costs $4.99 a month or $39 a year. Lifetime options are listed at 89.00 USD once and 199.00 USD once. CitePlain describes its focus as individual citations rather than replacing a research reference manager.

Yomu AI Citation Generator formats bibliography and in-text citations from a DOI, URL, title or bibliographic details entered by hand. The web tool offers quick lookup or manual entry, and users can edit details when a lookup is incomplete or unclear. It produces bibliography entries and in-text forms, including narrative citations, and shows BibTeX entries. The listed citation styles include APA, MLA, Chicago, ACS, AMA, IEEE, CSE, Turabian, ASA, Bluebook, APSA, BibTeX, NLM, Vancouver and ASME. Users can copy citations or export them to Word or PDF. Yomu describes the generator as free to use without signup and advises checking details against the original source. The generator is linked with Yomu's writing tools; its broader product includes a document assistant, AI autocomplete, editing commands, a plagiarism checker, a source library and research chat for PDFs, images and web search. The Pro plan is $10/mo billed annually, and Ultra is $17/mo billed annually. Yomu says its tools are intended to assist, not replace, students' own writing and research.
