AI email drafts that sound like you wrote them
Share examples of emails you have written and Replai scores and profiles your tone, typical reply length, favorite phrases, and sign-off so future drafts match.
Connect Gmail or Outlook and incoming messages are automatically labeled Priority, Needs Reply, FYI, or Unsubscribe so the noise does not reach you.
Paste a received email or type a few bullet points and get a finished reply or full email written in your own voice.
Record a call and Replai transcribes it, tracks who said what, and hands back a clean summary you can share.
