Google’s assistant inside Gmail. Help me write drafts a message from your prompt and refines it with Formalize, Shorten or Elaborate — a fast first pass, free with a qualifying Google plan.
Built around the question Gemini doesn’t ask: how should this email make the reader feel? A voice plus eight dials for the levers that decide whether a message lands confident, warm or urgent — and a reading of the real thread.
Gemini is a solid, fast assistant for a routine note. PersonaDraft is for the emails where tone decides the outcome — and it gives you explicit voice and dial control Gemini doesn’t. Many people use both.
Gemini’s refinements move along a few fixed axes. PersonaDraft exposes eight independent dials — assertiveness, warmth, urgency, brevity, formality and more — so you steer the message instead of accepting a preset. It pulls in the Gmail conversation so a reply to a frustrated client and a reply to a peer aren’t written the same way, and everything happens inside the compose window — see the AI email writer for the full flow.
