See it in actionYou draft a Slack reply, delete it, and start over โ 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 and WhatsApp desktop apps, on macOS and Windows. Same account, no browser in the middle.
While you type in Slack, Teams or WhatsApp, 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.
