Apple is introducing two new Audio Intelligence features, Live Rewind and Siri Recap, in the first watchOS 27.3 developer beta. Live Rewind displays the last 15 seconds of a conversation as text, while Siri Recap automatically creates summaries and key points from daily conversations.
Both features are opt-in and use Apple’s privacy-focused on-device processing and Private Cloud Compute. They require an Apple Watch Series 12 or Ultra 4 paired with a compatible iPhone 16 or newer. Initially, they support English only and will not be available in the EU at launch.
