About Logseq

Logseq is an open-source platform for knowledge management and collaboration that puts privacy and local storage first. Notes are organized as linked blocks in an outliner, forming a knowledge graph, and topics show it works with both Markdown and Org-mode files and can be backed by Git.

The project is moving toward a database-backed version that introduces DB graphs. That version is in beta, comes with a new iOS mobile app in alpha and a Real Time Collaboration approach to syncing graphs across devices or working with others, also in alpha. Because data loss is possible while these features mature, the maintainers recommend automated backups. A plugin API, themes and a public roadmap round out the ecosystem.

Logseq is written in Clojure and ClojureScript under the AGPL-3.0 license, and desktop builds are available from the releases page. It appeals to researchers, students and knowledge workers who want a personal wiki with bidirectional links and full ownership of their files.
