Apple has opened its Siri AI platform to all app developers, allowing them to integrate their applications’ content and functions into the voice assistant through a new Developer Preview announced on Tuesday.
The feature is available in the beta versions of iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3.
Previously, developers could only integrate their applications with Siri through categories predefined by Apple.
However, the company is now allowing them to use App Intents to make custom actions available to the assistant.
Examples include tracking deliveries, booking reservations and placing orders.
Apple is also introducing a feature called skills, which allows developers to train Siri AI to perform multiple actions through a single request.
The assistant can also retrieve any item indexed by Spotlight search, expanding its capabilities beyond the content covered by Apple’s existing categories.
“So people can just ask for help in their own words,” Apple wrote.
Users will not always need to mention an app by name when making requests to Siri, according to The Verge, which cited Apple’s documentation.
This applies when an app is open on the screen, displaying a Live Activity or already involved in an ongoing Siri conversation.
Apple has also begun extending the same capabilities to 15 of its own applications, including Mail, Maps, Photos and Safari.
For instance, users can ask Siri to locate a coffee shop they visited the previous week or archive files they have not opened in more than a year.
Siri AI is still unavailable in the European Union on iOS, iPadOS and watchOS, with Apple saying it is working with EU authorities to establish a way forward. The feature is also restricted to users aged 13 and above.
Apple’s announcement also confirmed that some Apple Intelligence features are subject to daily usage limits, particularly those that rely on the company’s servers.
The restrictions cover Siri AI, photo editing tools, Image Playground and cloud-based models available through the Shortcuts app.
“Expanded access to such features will be available for a fee in the future,” Apple wrote.
