Logically vs Papis

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.

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.
