What to know about Logseq

Logseq is a free, open-source knowledge management and note-taking application that uses a local-first, markdown-based outliner with bidirectional links and a graph view. Popular among researchers, developers, and knowledge workers who want privacy-first note-taking without vendor lock-in. Logseq lets you build a personal knowledge graph where every note can reference every other note, creating a connected second brain that you fully own.
