+### Apple Intelligence
+
+[Apple Intelligence](https://developer.apple.com/documentation/Updates/Apple-Intelligence) is now available for devices on iOS 18.1 and later. For Braze, the most relevant feature is notification preview summaries, which uses on-device processing to collapse and generate text summaries for groups of related push notifications from a single app. Summaries can be expanded to view the original contents of each individual notification.
+
+Keep in mind, this feature must be manually enabled by the user, meaning you won't have control over the specific behavior or content of your app's notification summary. However, this does not impact analytics or reporting features, such as push-click tracking.
