Overview
- Help Me Write, AI thread summaries, and personalized Suggested Replies are now available at no cost to U.S. Gmail users in English.
- AI Overviews that answer natural‑language questions about your inbox and a Grammarly‑like Proofread tool are limited to Google AI Pro and Ultra subscribers.
- A new AI Inbox that surfaces “Suggested to‑dos” and “Topics to catch up on” is in testing with trusted users, with broader access planned in the coming months and initial availability on the web for consumer accounts.
- Google says personal email content is processed within an isolated privacy architecture, is not used to train its foundational models, and all AI features can be turned off.
- Independent reviews highlight ongoing accuracy risks, and Gmail displays notices that Gemini can make mistakes, encouraging users to verify summaries and answers.
