you don't understand.

Translate, refine, learn
Get instant translations, tone adjustments, and idiom breakdowns. Then dismiss and keep working.
The Lzen Arsenal
Built for absolute efficiency.
Capture it, translate it.
A built-in screen capture tool (Sniper Overlay) instantly extracts and translates text from images, videos, or unselectable apps.
Appears at the speed of thought.
A global shortcut (Ctrl+Alt+Z) summons Lzen anywhere on your computer. A minimal 'Ghost Window' appears in overlay. Translate, rephrase, and dismiss without leaving your workflow.
The AI that adapts.
A dynamic AI engine that evaluates text complexity to always select the fastest and most accurate model.
80+ languages, and counting.
Translate into 80+ languages out of the box, from Spanish to Korean to Arabic, with new ones added every release.
Sounds like you, not a robot.
Pick a tone, literal, natural, casual, formal, or learner, or write your own custom style. Every translation adapts to it.

- 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.
