Apple opens Siri AI to third-party apps in iOS 27.3 Developer Preview

Apple will now let Siri AI perform actions across third-party apps. With the iOS 27.3 update, rolling out on Tuesday, Apple announced that developers can integrate Siri AI's new features in "all apps." That lets the voice assistant draw on a user's personal context, process natural language prompts and use on-screen awareness to complete requests. The update is rolling out as part of a Developer Preview.

It also adds a feature called "app skills," which third-party developers can create to combine several tasks into a single action. In its developer documentation, Apple says users won't have to mention an app's name in a request while the app is in the foreground, during a Live Activity, or in a conversation with Siri AI about the app.

Apple gives a ride share example: a person might request a ride with a ride share app, follow updates to the app's Live Activity while they wait for the ride to arrive, then ask to move the pickup location by saying 'Hey Siri, change my ride pickup to a new address.' As noted by 9to5Mac, Apple previously made a smaller set of features available to third-party developers.

Apple is bringing Siri AI's expanded capabilities to its own apps as well: Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts and Weather. According to Apple, users can do things like find a coffee shop they visited last week or archive files that haven't been opened in over a year. The company also notes that users can ask Siri AI what it can do in each app.

Key facts

  • Apple says developers can integrate Siri AI's new features in "all apps" as part of iOS 27.3, rolling out on Tuesday as a Developer Preview.
  • Siri AI can draw on personal context, process natural language prompts and use on-screen awareness to complete requests.
  • A new "app skills" feature lets third-party developers combine several tasks into a single action.
  • Per Apple's developer documentation, users won't need to name an app while it is in the foreground, during a Live Activity, or in a conversation with Siri AI about that app.
  • Siri AI's expanded capabilities are also coming to 15 Apple apps, from Calendar and Files to Safari and Weather.

Why it matters

Until now Apple made only a smaller set of features available to third-party developers, as 9to5Mac noted. This update lets Siri AI act across third-party apps, not just Apple's own. Users can also skip naming the app in some situations, such as when the app is in the foreground or during a Live Activity.

Who it affects

Third-party developers, who can now integrate Siri AI's new features in their apps and create app skills. Users of those apps are affected too, as are users of Apple's own apps: Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts and Weather.

How to use it

Developers can integrate Siri AI's new features in their apps through the iOS 27.3 Developer Preview and can create app skills that combine several tasks into one action. Apple's developer documentation describes the behaviour. Users can ask Siri AI what it can do in each app. In Apple's own apps, examples include finding a coffee shop visited last week or archiving files not opened in over a year.

How solid is it

The report comes from The Verge and is based on Apple's announcement and its developer documentation. The update is a Developer Preview, and the report's image caption says Siri AI will soon be able to carry out tasks across a wider range of apps. Only the day of the rollout (Tuesday) is given, not a calendar date. The report names no third-party apps using the features beyond the generic ride share example.

Risks and caveats

This is a Developer Preview, not a general release, and the report does not say when it reaches the public. It does not list supported devices, regions or languages. It gives no technical detail on how app skills are built or how personal context is handled for privacy, and it does not say which AI model powers Siri AI. No reactions from developers or analysts are quoted.
