JabRef vs Logically

JabRef is a free, open-source citation and reference manager for collecting and organizing research sources. It works natively with BibTeX and BibLaTeX libraries stored as text, imports references from more than 15 formats, and extracts metadata from PDFs. Users can search scientific catalogs such as CrossRef, Google Scholar, PubMed, Springer, arXiv, and zbMATH. Library tools include hierarchical collections, keywords and tags, advanced search and filters, duplicate merging, and customizable citation keys. JabRef supports cite-as-you-write workflows with Word and LibreOffice/OpenOffice, and can send citation keys to editors including Emacs, LyX, TeXstudio, Vim, and WinEdt. Its browser extension collects bibliographic information from websites, though the documentation warns it is non-functional on Chrome. Teams can share a SQL database, and SSL connections are supported; SSL testing is documented only for PostgreSQL. Since version 6, users can summarize papers and chat with them through external AI providers, which process requests and linked PDFs. The project directs users to documentation and a community forum for help, with bug reports handled through GitHub.

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.
