Apple Opens Siri AI Developer Preview for Custom App Integrations

PUBLISHER ARTICLE PREVIEW

From the original article

Apple announced on November 3, 2026 that its Siri AI Developer Preview is open to all developers through the iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3 betas. Apps can expose custom content and actions through App Intents, allowing Siri AI to handle requests such as checking deliveries, booking reservations, and placing orders.

The opening extends Siri AI beyond actions and data that fit Apple’s system-defined app schemas. Integrations can draw on personal-context understanding and onscreen awareness, letting people phrase requests in their own words, and Siri AI can surface any entity in Spotlight’s semantic index rather than only entities matching an existing schema. Apple has begun rolling out related capabilities across its own apps, including Calendar, Files, Mail, Maps, Messages, Photos, and Shortcuts; examples include finding a previously visited coffee shop and archiving files unopened for more than a year.

Under the Developer Preview documentation, invocation depends on context. A person does not need to name an app while it is in the foreground, while a Live Activity is active, or when continuing a Siri conversation that already included the app. Background requests require the app’s name. For example, a ride-hailing customer could follow a Live Activity and then ask Siri to change the pickup address without restating the app.

Siri AI can also find content in one app, transfer it to a specified second app, and perform an action there. Apple’s example sends a user’s favorite sneakers through a messaging app after resolving the recipient through Contacts. Requested custom content can appear in developer-supplied card snippets that use the app’s own views and branding.

No new entitlement or separate developer program is required.
