Tired of your English giving away that it's your second language?
You write a Slack message or a LinkedIn note, then wonder if a stiff 'Dear Sir/Madam' or a literal idiom marks you as non-native. Your standups, reviews, and outreach all happen in English. BetterSend's Native Speaker tone rewrites your draft to read like a fluent global professional — without changing what you mean.

See the difference instantly
One click transforms your message — without changing your meaning.
Before
“Dear Sir/Madam, I am writing to you regarding the position that was posted. I have the skills required and I hope to be considered.”
After
Native Speaker“Hi — I came across the opening and I think I'd be a strong fit. I have [X years] of experience in [relevant area] and I'd love to learn more. Would you be open to a quick chat?”
Built for global developers
What gives away a second-language writer is not the same in every language. The Native Speaker tone starts from the one you actually wrote in.
Fix formal/informal register, article usage, and direct-translation idioms
Remove Brazilian English patterns and sound naturally fluent
Polish formal Tagalog-influenced English to global professional norms
Fix tense consistency and add natural hedging to technical messages
Start in your language, send in any language
Write naturally in your first language and instantly translate for international teammates.
Original (EN)
“Hi Sarah — I wanted to follow up on our Monday discussion. Could we schedule a short call this week to align on next steps?”
“"Hi Sarah — I wanted to follow up on the discussion from Monday. Would it be possible to schedule a short call this week to align on the next steps?"”
Write in your language. Send in theirs.
Mix Portuguese, Spanish, French — whatever comes naturally. BetterSend turns it into one polished message in the language you need.

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.
- Slack
- 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
