From rough draft to reviewed email
Improve an email in three simple steps—without leaving the app where you write.
Step 01
Select your draft
Highlight the email text you want to improve, whether you’re writing in Apple Mail or Gmail in your browser.
Step 02
Choose an improvement
Open TypeBoost with your keyboard shortcut. Your selected text is already there. Choose the Improve Email action and press Enter.
Step 03
Review the result
See exactly what changed. Keep what you like. Undo what you don’t. Insert the improved text back into your email.
AI suggests the wording. You make the call.
Keep the improvements you like and undo individual changes with a click, without losing the rest of the rewrite.
Your emails. Your style.
