Google has expanded its file summarization feature in Google Chat to mobile devices. Users can now tap the "Summarize" button within a Chat conversation to receive a summary of shared files. This feature uses Gemini AI to provide quick overviews of files like Docs, Slides, and PDFs directly within the Chat app. Admins need to ensure smart features and personalization are enabled for users to access file summaries. End-users can control this feature through their settings within Google products. The rollout starts October 14, 2025, and is expected to complete by mid-November 2025. The feature is available to various Google Workspace editions, including Business and Enterprise. It's also available for users with specific Gemini subscriptions. The functionality allows users to grasp the essence of shared files without leaving the chat environment. This improves efficiency and facilitates faster information consumption. This feature update enhances the collaborative capabilities of Google Chat.
