Google is rolling out new generative AI features to Gmail, including AI Overviews that summarize long email conversations and answer inbox questions (for Pro/Ultra subscribers). The 'Help Me Write' and 'Suggested Replies' features are now free for all users, while 'Proofread' remains premium-only. A new AI Inbox feature, currently in testing, prioritizes tasks and reminders from emails while filtering clutter based on user behavior and relationships. These features are powered by Gemini 3 and initially launching in English for U.S. users, with global rollout planned for coming months.
