Apple Opens Siri AI to Third-Party Apps in the iOS 27.3 Beta

Apple opened a Siri AI developer preview on November 3 that lets any app add its own actions and content to Siri AI. Apps that use it run only in Xcode builds and with internal TestFlight testers until App Store submission opens in the spring.

The preview runs in the iOS 27.3 beta and the matching iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas. Apps join through App Intents and can bring their actions into Siri AI without a new entitlement or developer program.

The Siri AI developer preview lets Siri run an app’s own actions

Siri AI can find an app’s custom content and run its custom actions, including ones that do not fit Apple’s built-in app schemas. When an app offers the actions, Siri AI can check a delivery or book a reservation.

People do not have to name the app while it is in the foreground, while its Live Activity is running or when they continue a Siri conversation that already mentioned it. In the background, the request has to name the app, such as asking whether sneakers you liked in an app are on sale.

Siri AI can also pass content from one app to another, such as finding your favorite sneakers in a shopping app and sending them to your partner through a messaging app. The answer appears in a card snippet built with the developer’s own views, so it keeps the app’s branding.

For requests that take several steps, developers can write app skills that teach Siri AI how to combine multiple actions into one experience. Siri AI can also surface any entity in the Spotlight semantic index, including ones that do not match an existing schema.

Apple’s own apps already work this way, including Mail, Messages, Notes, Photos and Safari, and you can ask Siri AI what it can do in each app to see examples.

Testing stays in Xcode builds and internal TestFlight until spring

Developers can test the preview by building apps in Xcode with a development profile and running them on an Apple Intelligence device, or by sending builds to internal testers in TestFlight. External TestFlight testers and App Store versions of an app do not get the preview features, even when the app already uses App Intents.

Xcode includes a Siri Integration Advisor that suggests improvements to an app’s App Intents. A new Siri Evaluations framework lets developers script requests to Siri AI, measure the results and catch changes as they update their intents and entities.

App Store submission for these features opens in the spring, and they first reach customers in a few months. Apple will share terms and usage policies for Siri AI experiences later, and the App Intents API and Siri behavior may change during the preview. Developers can ask Apple engineers questions in Apple Intelligence Group Labs on November 4 at 9 a.m. Pacific and on November 5 at 6 p.m. Pacific.

Siri AI still has language, region and usage limits

The Siri AI languages are English, French, Japanese, Korean, Portuguese and Spanish, with Traditional Chinese, Norwegian, Turkish and Vietnamese due soon. It needs an Apple Intelligence device and is still in beta.

Siri AI is unavailable in the EU on iPhone, iPad and Apple Watch, and Apple says it is working with the EU on a path forward. It is also not available for users under 13.

Daily usage limits apply to Siri AI, Image Playground, the intelligent photo editing tools and the AFM 3 Cloud models in Shortcuts. The limits vary by feature, request complexity and system demand, and Apple will charge a fee for expanded access in the future.
