Overview

Logseq is a joyful, privacy-first, open-source platform for personal knowledge management and collaboration that works on top of local plain-text Markdown and Org-mode files. Unlike proprietary note-taking apps, Logseq gives you complete control over your data, storing everything locally in plain-text files that you own forever. The platform combines powerful outliner-based organization with knowledge graph visualization, making it ideal for building your personal knowledge garden or second brain. Logseq's unique outliner approach treats every bullet point as a block that can be referenced, linked, and reused throughout your knowledge base, creating an interconnected web of thoughts. The built-in whiteboard feature provides a spatial canvas where you can organize ideas visually using shapes, drawings, website embeds, and connectors. With features like backlinks, page and block references, PDF annotation, task management with TODO tracking, spaced repetition flashcards, and Zotero integration for research, Logseq serves students, researchers, writers, and knowledge workers who value data ownership and privacy. The platform's extensible plugin ecosystem allows community developers to add AI capabilities like semantic search, chat with notes, and smart connections, while the new database version introduces enhanced performance. Completely free and open-source with cross-platform support for macOS, iOS, Windows, and Linux, Logseq includes real-time collaboration for syncing graphs across devices.
