Apple has opened a Siri AI developer preview that lets app makers connect their own actions and content to the assistant. It's a step toward asking Siri to do more inside the apps you use, but it doesn't mean those new integrations are available in your App Store downloads.
That distinction matters more than the breadth of the announcement. Developers can start building now; customers still have to wait for those experiences to ship. If you've been hoping Siri could handle a particular task in your favorite app, this is a reason to watch that app's release notes rather than assume the feature has arrived.
What app makers can build
In its Siri AI announcement, Apple says the preview arrives with the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas. It expands the use of App Intents, the mechanism through which developers expose app functionality to the system, to custom actions and information.
Apple's examples include checking a delivery, making a reservation and placing an order. It also introduces app skills for combining several actions into a more complex task. Those are examples of what developers can support, not a promise that every delivery service or restaurant app already works.
The company's timeline remains broad: it expects the preview's capabilities to start reaching customers in a few months, with App Store submissions opening in the spring. It also says further details about terms and usage policies will follow.
Why your apps won't all change at once
The developer preview documentation draws a firm boundary: Siri can use only the custom content and actions an app explicitly makes available through App Intents. Installing a beta doesn't give it unrestricted control over every app.
Context also affects how you ask. When an app is in the background, Apple's documentation says you need to mention it in the request. With the app in the foreground or an active Live Activity, that name can be unnecessary. Developers can provide branded cards to present the results.
Testing is limited to development builds and internal TestFlight testers. External TestFlight testers and people downloading the app from the App Store don't get the preview functionality. Apple also warns that the APIs and Siri behavior may change during the preview.
For app makers, the useful work now is choosing a few clear tasks and checking how reliably Siri completes them. For everyone else, wait for your app's own announcement of supported actions and availability before relying on Siri for that workflow.
