watchOS 27.3 brings new Siri AI features to Apple Watch soon

What is coming in watchOS 27.3

Apple Watch users will get a software update next month that brings three new features, according to 9to5 Mac. The release, watchOS 27.3, focuses mainly on Siri AI, the assistant version Apple has been expanding since its launch.

The update adds new app actions for Siri AI across built-in apps such as Calendar, Mail, Maps, Messages, Music, Notes, Photos and Weather. This means the assistant will be able to carry out more tasks inside Apple's own apps directly from the wrist.

Four new languages for Siri AI

The second change concerns language support. watchOS 27.3 adds four new languages for Siri AI: Chinese (traditional), Norwegian, Turkish and Vietnamese.

Language expansion has been a steady theme for the assistant, and this update continues that pattern. Readers who use one of these languages will be able to interact with Siri AI on their watch in their own language once the update lands.

Live Rewind on the newest models

For the latest Apple Watch models, the update introduces an Audio Intelligence feature called Live Rewind. According to Apple's website as cited by 9to5 Mac, double-pressing the Digital Crown shows a text snippet of what was said in the last 15 seconds, so users can catch something they missed.

From there, users can ask Siri about the content of the snippet or save it to the Siri app. Apple demonstrated the feature in September, showing it used at a restaurant when a wearer missed part of a server's explanation of the menu.

The feature may not suit every situation. 9to5 Mac's writer notes that simply asking a person to repeat themselves can be easier, though there may be other cases where Live Rewind proves useful. That assessment is the author's opinion, not a confirmed Apple statement.

Siri Recap is limited and off by default

The third new feature is Siri Recap, which creates automatic logs of what happens in a user's day-to-day life. It only works on Apple Watch Series 12 and Ultra 4, and it is switched off by default.

Most recaps will not be needed and are automatically deleted after a week. The 9to5 Mac author, who says they have been trying the feature in the pre-release software, reports that it helps at times when recalling details from conversations. As this is based on personal testing, readers should treat it as an early impression rather than a verdict on the final release.

Who gets the new features and what to expect

All Apple Watch users will receive the Siri AI app actions and the four new languages when watchOS 27.3 rolls out next month. The two Audio Intelligence features are more restricted: Live Rewind is limited to the latest Apple Watch models, and Siri Recap requires a Series 12 or Ultra 4.

Owners of older watches therefore get the language and app action improvements, while the newest hardware unlocks the audio features. Apple has not been named as confirming a specific release date in the report, so the exact launch day next month remains unconfirmed. When the update appears, users can enable Siri Recap deliberately if they want the automatic daily logs, since it will not be active on its own.
