Logseq
Local-first knowledge management with outliner and visual canvas tools
LogSeq is an open-source personal knowledge management tool that works directly with plain text files (Markdown and Org-mode) while providing powerful outlining, visualization, and organization features. It combines daily journaling, bi-directional linking, and visual canvas tools for knowledge organization.
What we love ❤️
- Truly free core functionality with all local features
- Works with plain text files in Markdown or Org-mode format
- Built-in whiteboard feature for visual organization
- Supports PDF annotation and task management
- Two-way sync between plain-text and outliner views
- Can sync with Dropbox/Google Drive through local folders
Worth noting 💡
- Pro version (upcoming) required for built-in storage sync and real-time collaboration
- Some features require community plugins which vary in quality
- Performance may decline with large databases (lots of linked references)
- Regular backups recommended as automated sync isn't built-in
- Mobile apps have limited functionality compared to desktop
LogSeq delivers a comprehensive knowledge management system that uniquely combines outliner functionality with visual organization while maintaining data ownership through plain text files. While the distinction between free and upcoming Pro features requires attention, the local-first approach and extensive customization options make it a powerful tool for personal knowledge management. It's particularly suitable for users who value data privacy, prefer plain text formats, and need flexible tools for organizing their thoughts visually and hierarchically.
