About Logseq

Logseq is a free, open-source (AGPL) note-taking and personal knowledge management app built around an outliner and a bidirectional-linked knowledge graph, storing everything as local Markdown/plain-text files. It's aimed at researchers, students, developers, and privacy-conscious individuals who want full control and ownership of their data rather than a cloud-locked notebook. What most sets it apart is its local-first, plain-text foundation combined with a powerful query language and an extensible plugin ecosystem.
