Apple has opened Siri AI to third-party developers. In a developer news post on November 3, 2026, the company said a new Developer Preview, starting with the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas, lets any developer integrate their app with Siri AI, which Apple describes as an entirely new version of Siri that is more capable, conversational and personal.
Integration runs through App Intents. Apple says apps can bring their content and actions directly into Siri AI, gaining access to personal context understanding, onscreen awareness and natural-language requests such as checking a delivery, booking a reservation or placing an order. For complex requests, Apple is introducing skills, which let developers teach Siri AI how to combine several actions into a single experience. Siri AI can also now surface any entity in the Spotlight semantic index, not only those that fit an existing schema.
Apple has already rolled the capabilities into its own apps, including Calendar, Files, Mail, Maps, Messages, Notes, Photos, Reminders, Safari and Shortcuts. Apple says the preview gives early access before Siri AI first ships to customers in a few months, and that App Store submission for these experiences opens in the spring. It will publish terms and usage policies later.
The preview requires an Apple Intelligence-enabled device set to a supported language: English, French, Japanese, Korean, Portuguese or Spanish, with Traditional Chinese, Norwegian, Turkish and Vietnamese to follow. It is not currently available in the EU on iOS, iPadOS and watchOS, and not for users under 13. Apple also notes that Siri AI is subject to daily usage limits, and that expanded access will be offered for a fee in the future.
For app developers, this makes App Intents the main route into Apple's assistant: apps that define their actions and entities well can be invoked through conversation without the user opening them. Apple's documentation for the program is published under the Siri AI Developer Preview section of the App Intents docs.
