In their own words
Logseq
Logseq is a free, open-source platform for knowledge management and collaboration, with tools for notes, tasks, and PDF annotation. It supports Markdown and Org-mode files, and connects information through block references, backlinks, linked references, and queries. Logseq supports note sharing and real-time collaboration, and lists Zotero as an integration. The product says users keep their data locally and can work fully on-device; offline access is listed. It is available on web, Windows, macOS, Linux, iOS, and Android. A plugin and theme ecosystem extends the app, with the homepage listing more than 150 plugins and at least 30 themes. Logseq Sync provides encrypted file syncing across devices. Its public-beta Sync service does not support multiple people using the same graph at once, and the maker warns that data loss can occur. The database version is in beta, while the new mobile app and real-time collaboration features are in alpha; the maker also warns of possible data loss for these. Personal use is free forever. Sync Backer costs $5 a month and Sync Sponsor costs $15 a month, each described as a monthly recurring donation.
TreeLine
TreeLine is a free, offline information organizer for Linux, Windows, and macOS. It stores records in a tree, with fields on each node acting like a small database. Fields can contain plain or rich text, HTML, numbers, dates, times, booleans, and URLs. One file can hold several node types, each with its own fields and formatting. Search commands find node data, while filters present matching nodes in a flat view. Node output can appear on screen, be printed, or be exported to HTML. Files use JSON and may be compressed or encrypted automatically. Import and export cover plain text, delimited tables, older TreeLine files, Mozilla and XBEL bookmarks, generic XML, and ODF text outlines. Additional exports include CSV, PDF, tab-indented text, and TreeLine format. Windows installers target Windows 10 and 11. Linux installation requires Python 3.9 or newer, Qt 6.4 or newer, and PyQt 6.4 or newer. macOS is not formally supported; a third-party MacPorts version is suggested. The free plan is free under GNU GPL v2 or later.
