See it in actionLosing time to the language barrier with clients?
A client messages you in their language, so you copy it into a translator — then draft a reply you're not even sure reads naturally. BetterSend translates incoming WhatsApp messages inline and rewrites your replies in fluent, professional language, right in the chat, without ever leaving WhatsApp.
A native app, not a browser tab
BetterSend runs inside the Slack, Microsoft Teams and WhatsApp desktop apps, on macOS and Windows. Same account, no browser in the middle.

Double-click a message

Grammar was never the hard part
Tone, not spell-check. Thirteen of them, because disagreeing with your manager and disagreeing with your teammate are not the same message.
It reads the draft you already wrote. The rewrite keeps your meaning and your structure, so what goes out is still yours.
You send it, never us. BetterSend only suggests, nothing leaves until you press Enter, and nothing you wrote is stored.
Privacy-First by Design
BetterSend only runs when you click Improve or Translate. Your messages are never stored, auto-scanned, or sent anywhere without your explicit action.
Only runs when you click — never in the background
Messages are processed and never stored
No tracking, no scanning, no passive reading of your conversations
