JabRef vs Papis

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.

Papis is a free, open-source command-line manager for documents and bibliographic records. It stores records in human-readable YAML files and lets users search by fields such as author, title, and tags. Importers can bring data from other bibliography managers and retrieve metadata from sources including arXiv and Crossref. Records can be exported to BibTeX and other formats. The project lists plugins for Vim, Neovim, and Emacs, plus integrations with rofi, dmenu, Zotero, and Firefox. Third-party Python entry-point plugins can add importers and downloaders, and a Python API supports custom scripts. A local web app starts with `papis serve`; the documented address is `http://localhost:8888`. Installation is described through pip, source code, Arch Linux AUR, Nix, and Guix. The project directs questions to GitHub Discussions and bugs to GitHub Issues. If no importer exists for a website, users may need to download its PDF and enter metadata manually.
