Logseq

Outliner-style knowledge graph on top of local markdown files.

Note-Taking & Knowledge AppsWindowsmacOSLinuxiOSAndroidFreeOpen source

Logseq is an open-source outliner and knowledge base: every note is a bullet block, blocks link and embed across pages, and a graph view maps how your ideas connect. All data lives in local markdown files.

Daily journal pages, backlinks, flashcards, task states, and queries make it popular for personal knowledge management, and because the storage format is plain markdown, the same folder often doubles as an Obsidian vault.
