Siri AI is now open to all developers

Apple has opened a Developer Preview in the iOS 27.3 betas that lets any app bring its content and actions into Siri AI through App Intents, rather than only the categories Apple defined in advance. Developers can also write ‘skills’ that teach Siri AI to combine several actions into a single job; Apple says the features first reach customers in a few months, App Store submissions open in the spring, and the terms and usage policies are still to come.
