Write emails that sound native
every time you hit send.
BetterSend adds an AI Improve button right inside Gmail. Rewrite your email to sound like a fluent native professional — fixing non-native patterns and setting the right tone — before you hit send. Works in compose and reply windows.
Works on mail.google.com · Free forever · No credit card
Second-guessing every email to your manager?
You write to a client or your lead, then re-read it five times — wondering if it sounds rude, too stiff, or just non-native. English isn't your first language, but your work emails all happen in it. BetterSend rewrites your draft in one click, right inside the Gmail compose window.

One click transforms your message — without changing your meaning.

Before
“the client is wrong about this and i need you to tell them that”
After
Diplomatic“I'd like to address a misalignment with the client regarding this point. Could we schedule a brief call to align on the facts before the next meeting? I think a clear, unified response would be most effective.”

From executive to friendly, concise to supportive — choose the tone that fits your recipient and relationship.
Translate emails in 44 languages
Write to international clients and teammates in their language — right inside Gmail.

Also available as a native app
Slack, Microsoft Teams and WhatsApp on macOS and Windows — the desktop app writes straight into the composer, with no browser in the middle.

- Microsoft Teams
The button in the composer
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 a message
Double-click anything someone sent you to translate it or have it explained, right there, without leaving the conversation.
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
