Apple opened a Siri AI Developer Preview to any app developer in the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas, the company said in a developer post.

The preview lets apps expose their content and actions to Siri AI through App Intents, so users can ask for tasks in their own words. Apple said the preview gives "early access before first shipping to customers in a few months." It separately said App Store submission opens "in the spring." Apple has not yet published the terms and usage policies for these integrations.

Apple's post says "thousands of developers have already built integrations with Siri" for tasks such as directions, to-do lists, messages and audiobooks. The Verge, citing 9to5Mac, reported that Apple previously made a smaller set of features available2 to third-party developers. Apple said the broader preview means "more customers can discover and use apps just by asking." Apple's post carries no date and says "starting today"; The Verge reported the update as rolling out Tuesday.

What developers get

According to Apple's post1, apps can use Siri AI's "personal context understanding, onscreen awareness, natural language, and more." Siri AI can carry out "any custom action" a developer has built. Apple is also introducing "skills" so developers can "teach Siri AI how to combine several actions into a single experience." Siri AI can now surface any entity in the Spotlight semantic index, "not just the ones that fit an existing schema."

Apple said it has begun rolling out the new capabilities across its own apps, including Mail, Maps, Messages and Photos.

Limits and open questions

Apple said Siri AI is "currently unavailable in the EU in iOS, iPadOS, and watchOS" and that it is "working constructively with the EU in an attempt to find a path forward." Siri AI is available in beta in the 27.3 releases, including watchOS 27.3. It requires an Apple Intelligence-enabled device set to a supported language and is not available to users under 13.

Certain features that rely on server-side models, including Siri AI, are "subject to daily usage limits." Apple said those limits "may vary by feature, request complexity, system demand, system policies, and other factors." It added that "expanded access to such features will be available for a fee in the future." The post gives no price and describes no fee structure.

Apple said it will "follow up with more details about the terms and usage policies for experiences enabled through Siri AI." It scheduled Apple Intelligence Group Labs sessions for November 4 and 5.

The descriptions of Siri AI's capabilities and limits come from Apple's own documentation and have not been independently tested by Automatica.
