Your notes. Nobody else's.
Prevon keeps your notes locked on your own device. The AI runs on the device, not our servers — not even we can read them.
There is no public download today. Prevon is in a private beta while we harden the vault. Pick the route that fits you below.

Where it will run
The same encrypted vault on all five. Every one is listed as coming soon because that is the truth — the only build that exists today is the private beta, and it is not downloadable from this page.
- Windows
- macOS
- Linux
- Android
- iOS
