Private and flexible note-taking

Starts at Free
Great value

Obsidian core app is genuinely free with no feature gating, every note-taking and knowledge management feature works without paying.

Watch out

Sync ($4-5/month) is almost mandatory for multi-device users. While you can use free alternatives (iCloud, Google Drive, Git), they introduce sync conflicts that Obsidian Sync solves with end-to-end encryption and proper conflict resolution. Most serious users end up paying for Sync

  • +Extensible plugins
  • +Graph view

Weaknesses

  • -Sync costs extra
  • -Steep learning curve
