What is Logseq?

Logseq is an open-source, privacy-first note-taking application built around a block-based outliner rather than pages of free-flowing text. Every note lives locally on the user's device as plain Markdown or Org-mode files, and bidirectional links between blocks let users build a personal knowledge graph that can be explored visually. It ships with flashcards for spaced repetition, whiteboards, PDF annotation, and a Datalog-style query engine for surfacing structured information across notes.

The core desktop, web, and mobile apps are free forever for personal use, with over 150 community plugins and 30 themes for customization. An in-beta Logseq Sync feature adds encrypted cross-device syncing, currently funded through voluntary monthly contributions rather than a fixed subscription tier.
