Siri AI is now open to all developers
Apple's iOS 27.3 betas introduce a Siri AI Developer Preview that lets any app expose its content and actions through App Intents, with personal context understanding, onscreen awareness, and natural language. Developers can also define skills that chain multiple actions, and Siri can surface any entity in the Spotlight semantic index. App Store submissions open in spring, with customer shipping a few months later.
What this means for indie developers：Indie developers should start wiring core app actions into Siri AI via App Intents to capture a new voice-first discovery channel.
