What 'sounds like you' actually means for AI drafts

Generic AI replies have a tell. I hope this email finds you well. I wanted to circle back. Please do not hesitate to reach out. Nobody writes like that — but every model does, because it is trained on the average of everyone.

Voice matching means extracting how you specifically write. We profile eight signals from your sent mail: average reply length, greeting style, sign-off style, directness, deadline specificity, emoji and punctuation habits, formality range by recipient, and how you say no.

Deadline specificity turned out to be the most personal. Some people write I will get this to you soon. Others write Done by Thursday EOD. If a draft flips your style, recipients notice something is off even if they cannot say what.

The profile builds passively from the moment you connect Gmail — no training session, no thumbs-up grind. By the time drafts ship in Phase 2, the system already knows whether you are a Thanks! or a Best regards person.

And every draft is still a draft. You read it, you edit it or not, you tap send. The voice is yours. The judgment stays yours too.
