Logseq
Open-source outliner for networked thought with local-first storage
About Logseq
Logseq is built on the conviction that your data should belong to you — all notes are stored as plain text files on your file system, not on proprietary servers. The daily journal is the primary entry point, with bullets that can be linked, tagged, and referenced across the entire database. Bi-directional links and block references create a networked knowledge graph that surfaces connections between ideas. Queries allow Datalog-based searches across all notes, enabling dynamic views like 'all tasks due this week' or 'all notes mentioning a specific person.' The plugin ecosystem is mature, with extensions for flashcard learning, task management, and whiteboard sketching. Logseq is rebuilding its database architecture (DB version) which promises improved performance but is not yet stable for production use.
