CitePlain vs MyBib

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.

MyBib creates formatted bibliographies, citations, and works cited for academic assignments and papers. It can build references for books, journals, websites, and videos from a title or identifier such as a URL or ISBN. The maker says it supports over 9,000 citation styles, including APA, Chicago, Harvard, and MLA. Users can arrange sources in nested folders and create in-text citations that combine sources with a page, chapter, or section locator. Bibliographies can be downloaded to Word or Google Docs, imported into Zotero or Mendeley, or exported as BibTeX and JSON. MyBib is available on the web and through free Chrome, Firefox, and Edge extensions. Its free plan works without an account, has no project or citation limit, and stores work on the user's device by default. MyBib Plus costs $2 per month, paid annually at $24 per year, and adds server storage and access across devices. MyBib says it mostly remains usable without an internet connection.
