Why it works

Everything you need,
nothing you don't.

⌨️

Works everywhere

Mail, Slack, Chrome, Notes, TextEdit — any Mac app. No copy-paste, no switching tabs.

⚡

All tones at once

Four rewrites fire in parallel. Results appear as soon as they're ready — usually under 3 seconds.

🌍

Multilingual

Auto-detects your language and replies in kind. Override to English, French, Lëtzebuergesch, German, or Spanish.

✏️

Your style, trained

Paste your own writing samples per tone. Claude learns how you write, not just a generic template.
