Privacy-first platform for knowledge management and collaboration
Logseq is a local-first knowledge management platform supporting Markdown and Org-mode, featuring bidirectional linking, PDF annotation, task management, and visual whiteboard capabilities with extensible plugins.

Logseq is a knowledge management and collaboration platform built around privacy, longevity, and user control. Designed for researchers, writers, students, and knowledge workers, it provides powerful tools for capturing, organizing, and connecting information while keeping your data under your control.
The platform supports multiple file formats including Markdown and Org-mode, enabling flexible note-taking with bidirectional linking and graph visualization. Its Whiteboard feature offers a spatial canvas for visual thinkers to organize ideas using shapes, drawings, connectors, and embedded media. Built-in PDF annotation and task management tools streamline research and productivity workflows.
Logseq offers both file-based graphs (stored as plain text files) and database graphs (DB version, currently in beta). A growing ecosystem of plugins and themes enables customization for diverse workflows. The DB version introduces real-time collaboration (RTC) for multi-device sync and team collaboration, currently in alpha testing. Users can deploy Logseq as a desktop application or access it via web, with mobile apps available for the DB version.
When teams consider Logseq, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Academic Research Management
Annotate PDFs, link citations bidirectionally, and visualize connections between papers and concepts in a unified knowledge graph
Project Planning with Whiteboards
Map project components spatially, embed relevant notes and media, and connect tasks to knowledge base entries for holistic planning
Personal Knowledge Base
Build an interconnected second brain with daily journals, evergreen notes, and automatic backlinks that reveal emergent patterns
Team Knowledge Collaboration
Sync graphs across devices using RTC alpha, enabling distributed teams to co-create and maintain shared knowledge repositories
File graphs store notes as plain text Markdown or Org-mode files on your filesystem, while DB graphs (beta) use a SQLite database for improved performance and enable real-time collaboration features.
The DB version is in beta and data loss is possible. Automated backups or regular SQLite database backups are strongly recommended. Use a test graph with non-critical projects during beta.
Yes, Logseq is local-first and works fully offline. Your data is stored on your device, and sync features like RTC are optional for multi-device or collaboration scenarios.
Whiteboard provides a spatial canvas where you can arrange notes, shapes, drawings, website embeds, and connectors visually. It integrates with your knowledge base, letting you link canvas elements to existing notes.
Logseq offers desktop applications for Windows, macOS, and Linux, a web version, and mobile apps for iOS (with Android coming soon) for the DB version.
