CitePlain vs Logically

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.

Logically is a research workspace for managing references, reviewing literature, annotating files, taking notes, and writing papers. Its AI assistant can search, summarize, and compare references across libraries, with inline citations and data sources. The reference manager accepts PDF, DOCX, TXT, MDOWN, EPUB, and PPTX files, along with URLs and DOIs. Users can import reference data from Zotero, Mendeley, and EndNote in RIS, BibTeX, or CFF formats. Semantic Scholar Mode draws on a database of 200 million peer-reviewed papers, and Logically says it supports more than 10,000 citation styles. Shared libraries, invitations, and collaborator permissions support group work. The free Cite Extension inserts citations and bibliographies from a Logically library into Microsoft Word; compatibility includes Word on the web, Word 2019 or later on Mac, and Word with Microsoft 365 on Mac or Windows. Logically runs as an extension, on macOS and Windows, and on the web. Free costs nothing and includes 100MB storage with daily AI-use limits. Unlimited is listed at $12 a year, billed at $12 per user/month yearly.
