Apple opens Siri AI to all developers with iOS 27.3 and other 27.3 OS betas, letting any app bring its content and actions into Siri AI by using App Intents

Apps can now respond to your voice commands through Siri, making it easier to get things done without opening them manually.

Apple has released developer betas of iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3, enabling third-party developers to integrate their applications with Siri AI. This new version of Siri, described as more capable and conversational, can now incorporate content and actions from any app using App Intents. Developers can build custom actions, and Apple is introducing 'skills' to allow Siri AI to chain multiple actions together. Siri AI can also surface any entity from the Spotlight semantic index, not just those fitting predefined schemas. These capabilities have already been integrated into various Apple applications, such as Calendar, Files, and Mail. The developer preview allows apps to work directly with Siri AI, with App Store submission opening in Spring and a general customer release expected in a few months. Siri AI is available in several languages but is currently unavailable in the EU and for users under 13, with some server-side features subject to daily usage limits that may become a paid service.

The opening of Siri AI to all developers via App Intents signifies a strategic shift for Apple, moving beyond basic voice commands to a more integrated and intelligent assistant. By allowing developers to expose app content and actions directly to Siri AI, Apple is aiming to create a richer, more context-aware user experience across its ecosystem. This move challenges existing third-party voice assistants and could drive deeper engagement within the Apple platform, potentially increasing user stickiness.

This expanded integration could redefine how users interact with their devices, enabling complex, multi-step tasks to be performed with simple voice prompts. For developers, it presents a new, high-visibility channel to reach customers, but also a challenge to adapt their applications to Siri AI's capabilities and the new 'skills' paradigm. The future monetization of server-side features suggests a potential revenue stream for Apple beyond hardware, and a new cost consideration for power users and businesses.
