See it in actionMix Portuguese, Spanish, French, whatever comes naturally. BetterSend turns it into one polished message in the language you need.
You draft a Slack reply, delete it, and start over, still unsure if it sounds rude, too casual, or just non-native. English isn't your first language, but your standups, pull requests, and client emails all happen in it. BetterSend fixes that in one click, right where you're already typing.
BetterSend runs inside the Slack, Microsoft Teams, WhatsApp and Discord desktop apps, on macOS and Windows. Same account, no browser in the middle.
While you type in Slack, Teams, WhatsApp or Discord, a small BetterSend button appears next to the field. Click it, pick a tone, replace the draft.
Double-click anything someone sent you to translate it or have it explained, right there, without leaving the conversation.
BetterSend is not just spell-check. It helps you sound the way you want to sound.
Turn rough drafts into polished messages. Choose from 13 tones: professional, friendly, confident, diplomatic, and more.
Translate messages in Slack, WhatsApp, and LinkedIn into 44 languages right inside the conversation. No copy-pasting required.
Sound like a native global professional. Fix non-native patterns from Indian, Brazilian, LATAM, or Eastern European English.
Messages are processed only when you click Improve or Translate. We never store your message content.
Got a message you only half understood? One click and BetterSend explains what it means and what is being asked of you, in your language, without leaving the conversation.
Other tools translate text. BetterSend rewrites it like a native speaker would, inside the app you're already in.
