Google is integrating Gemini AI into Gmail, introducing features like AI Overviews to summarize long email threads and answer inbox questions. "Help Me Write" and enhanced "Suggested Replies" speed up email composition, while "AI Inbox" prioritizes important messages. These updates, powered by Gemini 3, aim to transform Gmail into a proactive personal assistant for managing crowded inboxes. While some advanced features remain exclusive to paid subscribers, core functionalities like AI Overviews and writing assistance are now available for free to all users, starting in the US with English.
