When local OCR isn't enough.
Handwriting, dense tables, rare scripts. Zen Vision Pro sends your lasso capture to a high-precision cloud OCR engine and reads what the local pass cannot. Included in every paid plan, with a generous daily fair-use allowance.

Safely.

- Cloud Sync: Instant and reliable sync powered by Supabase.
- Seamless continuity: Find your Z-Points and settings everywhere — your history stays put, right where you made it.
- Data protection: Secure authentication via Google Auth and confidential processing.
- Local-first history: Your translation history stays on your device and is never uploaded to our servers.
