Google Brings Gemini 3 to Gmail, Rolling Out AI Writing and Inbox Tools in the U.S.

The U.S.-only debut pairs free basics with paid upgrades, drawing fresh scrutiny of Google’s privacy assurances.

Overview

  • Help Me Write and upgraded Suggested Replies are now available to all Gmail users, while Proofread and some conversational inbox queries require Google AI Pro or Ultra subscriptions.
  • An experimental AI Inbox that prioritizes messages and surfaces to‑dos is limited to trusted testers using consumer Gmail accounts in the U.S.
  • The rollout starts in English in the United States, with Google saying more regions and languages will follow in the coming months.
  • Google says content analyzed in Gmail will not train Gemini and cites an “engineering privacy” barrier designed to protect inbox data.
  • Privacy advocates and vendors are urging caution and sharing steps to disable smart features, highlighting concerns about broad AI access to inbox contents.
