Siri AI is now open to any app developer, months before customers get it

Apple has opened a Siri AI Developer Preview to every developer. According to its announcement, covered by Techmeme, the new 27.3 betas let any app feed its content and actions into Siri AI through App Intents.

What developers can build today

Per Apple’s developer news post, users will be able to ask in their own words, and Siri AI can then run custom app actions such as checking a delivery, booking a reservation or placing an order. The route in is App Intents, the framework apps already use to expose actions to the system.

Apple names two additions. Skills let developers teach Siri AI to chain several actions into one experience. The Spotlight semantic index can now surface any entity, not only those fitting an existing schema. Apple adds that the rollout has begun across its own apps, including Mail, Maps, Messages, Photos and Safari.

This is early access. Customers get the features in a few months, and App Store submission for apps using them opens in the spring. Apple has published documentation and plans Apple Intelligence Group Labs sessions on November 4 and November 5.

Who can use it, and who cannot yet

Siri AI needs an Apple Intelligence-enabled device set to English, French, Japanese, Korean, Portuguese or Spanish. Apple lists Traditional Chinese, Norwegian, Turkish and Vietnamese as coming soon.

Apple says Siri AI is currently unavailable in the EU on iPhone, iPad and Apple Watch, and not available to users under 13. It also warns that some server-side features have daily usage limits and that expanded access will cost money later. Terms and usage policies for Siri AI experiences are still to come, so developers do not yet know the commercial rules they will ship under.

A platform move that follows the June keynote

Siri AI is not new this week. MacTech’s account of Apple’s June 8 developer release said App Intents updates would let apps connect to personal context, app actions and onscreen awareness. What changes now is that access is no longer gated. Bloomberg reported the same day that the beta also brings Watch AI listening tools, a Health app and China AI.

The approach fits Apple’s other recent AI work. On October 27 we reported that Keynote, Pages and Numbers got an OpenAI-backed assistant and MCP, an open protocol. Siri AI instead relies on Apple’s own framework, so an app’s visibility inside Siri depends on how well it describes its actions and data to the system.

What the announcement leaves open

Apple has not said what expanded access will cost, what the daily limits are or what the usage policies will require. It gives no date for the EU. Apple’s claims about how well the system handles natural-language requests have not been independently tested. Readers who want to try it need the 27.3 betas, a supported device and one of the six listed languages.
