Gmail is rolling out new AI features as part of its Gemini integration, aimed at transforming how users interact with their emails. Starting today, paying subscribers will access expanded AI Overviews, which summarize email chains and now include search functionality. Instead of simply showing a list of emails that match a search query, the AI will generate a formatted response containing relevant details and citations from the original messages. While AI Overviews have faced accuracy issues in the past, grounding the technology in email content could improve reliability. In addition to search enhancements, AI Pro and Ultra subscribers will see a new proofreading tool that offers suggestions for improving email clarity and style. This feature utilizes Gemini 3 models to provide more nuanced edits compared to standard spellcheckers, highlighting suggestions with dotted underlines. Lastly, Google is previewing an AI Inbox, which offers a more organized way to manage unread emails. This feature highlights important messages at the top under "Priorities," while less critical emails are summarized in a "Catch me up" section. The AI Inbox aims to streamline email management by using Gemini's capabilities to distinguish between urgent and non-urgent messages.
