Free your data from Notion.

Obsidian is private, free, and gives you complete ownership of your data.

Sharpen your thinking.

Switching from Notion you'll notice Obsidian's speed and customizability. Plus, total control over your data.

Lightning fast: Even with thousands notes, Obsidian is snappy. Fly through ideas as fast as you can type.
Works offline: Obsidian stores your data on your device, so you can access it quickly, wherever you are.
Extensible: With 1,000+ plugins and our open API, Obsidian can be customized to fit any workflow.
No lock-in: Apps come and go, but your notes should last. Obsidian stores your notes in non-proprietary plain text files.
Private: Your data is yours. No one else can read it, not even us. Sync is end-to-end encrypted.
100% user-supported: We believe in staying true to our principles. Obsidian is 100% supported by our users, not VC funding.
