Logseq
Logseq is a free, open-source platform for knowledge management and collaboration, with tools for notes, tasks, and PDF annotation. It works with Markdown and Org-mode files, and its linking features—block references, backlinks, linked references, and queries—help connect and revisit information. Logseq says data stays locally on the user’s device and that the app works fully on-device. It supports offline access, note sharing, and real-time collaboration, and lists Zotero as an integration. Versions are available for web, Windows, macOS, Linux, iOS, and Android. The plugin and theme ecosystem includes more than 150 plugins and at least 30 themes. Logseq Sync offers encrypted file syncing, but its public beta does not support multiple people using the same graph at once, and the maker warns of possible data loss. The database version is in beta; the new mobile app and real-time collaboration features are in alpha, also with a data-loss warning. Free is available forever for personal use. Sync Backer is 5.00 USD per month and Sync Sponsor is 15.00 USD per month, both monthly recurring donations.
Who it is for
Logseq may suit students, academics, writers, project managers, and developers who want linked notes, task management, or PDF annotation. Its local-first approach may appeal to people who want to work with data on their own device.
