Group chats and long messaging threads accumulate while users are away from their phones. Catching up means scrolling through dozens of messages to understand what happened. Users miss important context buried in conversation noise.

AI Notification Summaries condense long messaging threads into short, digestible overviews. When users unlock their phone, they see the gist of what they missed without reading every message. Powered by Gemini Nano running entirely on-device.

The feature activates only when the screen has been off, processing conversations locally and generating summaries that appear directly in the notification shade. Users can tap through to the full conversation when they want more detail.

Privacy by Design

All processing happens within the device's Private Compute Core. Messages are never sent to Google servers. The on-device Gemini Nano model handles summarization locally, maintaining complete privacy while delivering intelligent features. Users can exclude specific apps from summarization.
