Swiss privacy-first tone helper
Make your messages land the way you intend.
Tone Keyboard is a system keyboard for iOS and Android that offers exactly one inline rewrite suggestion based on who you are writing to - without app switching, without chat mode, and without storing your message content.
Works wherever you type
Messaging, email, social media, comments, reviews, forms, and other everyday text fields - without leaving the keyboard.
- System keyboard for iOS and Android
- No separate composer workflow
- Inline suggestion, then back to typing
Most writing tools optimize for productivity. Tone Keyboard optimizes for social safety - reducing the everyday stress of “Does this sound rude?” and “Will this escalate?”
Context, not personality
The keyboard uses a relationship context you choose. It does not build behavioural profiles, read your contacts to infer tone, or maintain a conversational memory.
