Logseq
A privacy-first, open-source knowledge base.
Logseq is an open-source knowledge management platform designed to help users capture, structure, and review information. It addresses the problem of disconnected notes and information overload by providing a local-first outliner tool where notes are stored as Markdown files, giving users full control over their data. The platform helps turn daily information into structured, searchable knowledge.
Key capabilities include linked references, block references, queries, and search for connecting ideas, along with flashcards for memorization and PDF annotation for research. It supports task management, journaling, and daily notes. Logseq offers mobile apps for iOS and Android, a web app, and an optional encrypted sync service to keep notes updated across devices. The platform is extensible with over 150 plugins and 30+ themes.
Logseq is designed for students, academics, writers, project managers, and developers who deal with large amounts of information. It is free forever for personal use, open source, and privacy-first, with data stored locally. The pricing page does not provide details on paid plans or editions.
