// about Logseq

Logseq is an open-source, privacy-first knowledge management tool based on a local-first outliner and graph database that links blocks and pages into a connected knowledge graph. Its AI features include smart search, auto-linking of related concepts, and integration with LLMs for in-context question answering over your notes. Researchers and developers favour Logseq for its Git-friendly plain-text storage and powerful query language that turns a personal knowledge base into a queryable database.
