Bibcitation vs Petal

Bibcitation is a free web and browser-extension tool for creating citations, bibliographies, references, and works cited. It can automatically cite books, journal articles, and websites. Supported styles include MLA, APA, Chicago, IEEE, and more than 9,000 other formats, with CSL tools used for formatting. Users can copy a bibliography or export work to Google Docs, Word, and other popular formats. Add-ons are listed for Chrome, Google Docs, and Microsoft Word. The free plan costs nothing, and the homepage states no usage limits. Organizations can add a custom citation button to a webpage through a book ISBN link; that free integration currently supports books only. Bibcitation’s privacy policy says browser data may include browser type, language, referring site, requested pages, request time, and potentially IP addresses. Collected information is stored and processed in the United States. The policy is marked last updated September 24, 2020. Users must be at least 13, or older where local rules require it.

Petal is a web-based research assistant and reference manager for academic work, also available as a browser extension. Its plans include a free tier and paid options listed from $4.99/user/mo (annual). It helps users narrow literature reviews and compare studies, while providing a library for uploading and organizing PDFs with collections, metadata, and tags. AI tools offer translation, summaries, explanations, key-point extraction, suggestions for questions and search terms, and conversational assistance. Shared workspaces support group projects, co-authored papers, and reviews. The citation generator supports more than 10,000 styles and can copy citations or export them to BibTeX or Word. References can be brought in through identifiers such as DOI, PMID, ArXivID, ISBN, ISSN, and EAN, or by capturing metadata from URLs. Browser add-ins are listed for Chrome, Firefox, and Safari, alongside a Word add-in for citations and bibliographies. The free plan includes 1 GB storage, one seat, three guests, 400 AI credits, two collections, and three annotations per document; citation export is not included.
