ToneSwap

Rewrite emails and messages in Gmail, Outlook and LinkedIn so they sound like you. Reply, follow up or say no in one click.

Fix any email before you hit Send.

ToneSwap adds a Rewrite button right next to Send in Gmail. One click polishes your draft: spelling, grammar and punctuation fixed, nothing else changed. Or pick what the email needs: • Situations: Reply, Follow up, Say no, Apologize, Ask for something • Styles: Make it shorter, Work email, Quick reply, Plain English

You see the rewrite before anything changes. Replace your draft, copy it, or try again. Select a sentence to rewrite just that part. Your signature and the quoted thread are never touched, and Undo brings your original back.

Works beyond Gmail too: select text in Outlook, LinkedIn, Slack or any text box and click the ToneSwap button, or paste into the toolbar popup.

Sign in and ToneSwap learns how you write, so rewrites sound like you, not like generic AI. Every rewrite shows how closely it matches your voice. You can turn voice learning off anytime in Settings.

Free: 2 rewrites a day without an account, 5 with a free account. New accounts get 14 days of Pro free, no card needed. Pro gives you 100 rewrites a day, more styles, longer emails and our strongest model.
