Apple has opened Siri AI to every app developer. Starting with the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas released on November 3, a new Developer Preview lets any developer connect their app to Siri AI, the rebuilt version of Siri that Apple describes as "profoundly more capable, conversational, and personal."
Until now, third-party support was narrow. 9to5Mac notes that earlier Siri AI versions were "limited to a much smaller set of supported schemas," and calls this the first time any app can create Siri AI integrations. Customers won't see those integrations yet: Apple says the preview gives developers early access "before first shipping to customers in a few months," with App Store submission opening in the spring.
What developers can now build
The mechanism is App Intents, the framework apps already use to expose actions to the system. Apple's developer announcement says any app can now bring its content and actions directly into Siri AI this way, so Siri AI can carry out whatever custom action a developer has built. Apple's own examples are checking a delivery, booking a reservation and placing an order. Those actions can draw on Siri AI's newer abilities, which Apple lists as personal context understanding, onscreen awareness and natural language.
Two further changes go beyond single actions.
- Skills. For complex requests, Apple is introducing skills, which let developers teach Siri AI how to combine several actions into a single experience. 9to5Mac points to Apple's documentation example, in which Siri finds custom content in one app, transfers it to another and performs an action there, such as sending details of a pair of sneakers to a partner through a messaging app.
- Spotlight content. Apple says Siri AI can now surface any entity in the Spotlight semantic index, not only those that fit an existing schema.
9to5Mac also reports that in iOS 27.3 people often won't need to name the app at all. Its example: with a ride-sharing Live Activity running, a request to change the ride's address goes to that app automatically.
Apple's own apps go first
Apple says it has started rolling the same capabilities out across its own apps: Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts and Weather. MacRumors lists some of what that means in the beta. In Mail, Siri AI can unsubscribe from mailing lists and undo a recently sent message. In Safari, it can clear browsing history, manage tabs and windows, save articles to the Reading List and close duplicate tabs. In Files, it can organize content and delete files that haven't been opened for a set period.
Limits worth knowing
Siri AI is still labeled beta and needs an Apple Intelligence-enabled device set to a supported language. Apple lists English, French, Japanese, Korean, Portuguese and Spanish today, with Traditional Chinese, Norwegian, Turkish and Vietnamese coming soon.
There are other restrictions in Apple's notes. Siri AI is currently unavailable in the EU on iOS, iPadOS and watchOS, where Apple says it is working with the EU "in an attempt to find a path forward." It isn't available to users under 13. And Apple says features that rely on server-side models, Siri AI among them, are subject to daily usage limits, adding that "expanded access to such features will be available for a fee in the future." It hasn't said what that will cost.
What happens next
Apple says it will follow up with details on the terms and usage policies for experiences built on Siri AI. Its engineers are running Apple Intelligence Group Labs sessions for developers on November 4 and 5. The bigger dates are further out: the customer release "in a few months" and App Store submissions in the spring.
Cole's take: The skills system is the piece that changes how this works. A single App Intent tells Siri what one app can do; a skill describes how several steps fit together, and multi-step requests are where an assistant's usefulness is really tested. The usage-limit note deserves as much attention, though. If the most capable Siri requests are metered, with paid expanded access promised, developers will want those terms before they design around Siri AI, and Apple hasn't published them yet.
