Google is updating the Gmail app to automatically generate and display AI summaries for emails on Android and iOS.Previously, users had to manually tap a button to summarize emails, but now Google will provide summaries automatically for relevant emails.The AI summaries are generated using Gemini to provide a brief list of bullet points breaking down the content of longer messages or email threads.The summaries will be displayed at the top of the Gmail app, making it easier for users to quickly grasp the key points of their emails.
