Apple unveils Siri AI developer preview, opening the platform to third-party apps

Apple has announced that it is opening Siri AI to outside developers, launching a developer preview alongside the iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3 betas. According to the announcement, the preview lets any developer integrate their app with Siri AI through App Intents, bringing an app's content and actions directly into the assistant. Apple frames the move as a way for businesses and developers to reach and serve customers through capabilities including personal context understanding, onscreen awareness, and natural language, so users can ask for help in their own words and have Siri AI carry out custom actions such as checking a delivery, booking a reservation, or placing an order.

The company also introduced skills, which let developers teach Siri AI to chain several actions into a single experience, and said the assistant can now surface any entity in the Spotlight semantic index rather than only those matching an existing schema. Apple noted that it has already been rolling out related capabilities across its own apps: Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts, and Weather, with examples like finding a coffee shop a user visited last week or archiving files untouched for over a year.

Apple described the release as an early look ahead of a broader customer rollout in a few months, with App Store submissions opening in the spring. Siri AI is in beta across iOS, iPadOS, macOS, watchOS, and visionOS 27.3 and requires an Apple Intelligence-enabled device set to a supported language; it is available in English, French, Japanese, Korean, Portuguese, and Spanish, and Apple cautioned that some features may not be available in all regions or languages. The company said it will follow up with more details on terms and usage policies for Siri AI–enabled experiences, and is hosting Apple Intelligence Group Labs sessions on November 4–5 for developers to consult with its engineers.
