Apple opens Siri AI to every app developer in iOS 27.3 beta

Apple has opened its new Siri AI to all third-party apps — at least in beta. In a developer news post on November 3, the company said a new Developer Preview in the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas lets any developer integrate their app with Siri AI.

What developers can do

• App Intents for Siri AI. Apps can expose their content and actions so Siri AI can use them with personal context, onscreen awareness and natural language. Apple's examples: checking a delivery, booking a reservation or placing an order — just by asking.
• Skills. For complex requests, developers can "teach" Siri AI how to combine several actions into one experience.
• Wider Spotlight reach. Siri AI can now surface any entity in the Spotlight semantic index, not only those that fit an existing schema.

Apple's own apps — including Calendar, Files, Mail, Maps, Messages, Notes, Photos, Reminders, Safari and Weather — are already getting these capabilities.

When users get it

This is an early preview: Apple says the features first ship to customers "in a few months", and App Store submissions open in the spring. Siri AI needs an Apple Intelligence-enabled device and currently works in English, French, Japanese, Korean, Portuguese and Spanish. Apple notes Siri AI is still unavailable in the EU on iOS, iPadOS and watchOS, and not available to users under 13.
