Apple has opened Siri AI's new app actions to any developer in the iOS 27.3 beta. The App Intents preview lets third-party apps expose their content and custom actions to Siri, while customer-facing integrations are still months away.
App Intents already let thousands of developers handle requests such as sending a message or managing a to-do list. The new preview broadens what Siri AI can understand and do with app content. Apple says an app can expose an entity in Spotlight's semantic index even when it does not fit an existing schema, and Siri AI can draw on personal context and what is onscreen to interpret a request.
That could turn a natural-language request into a delivery check, a reservation, or an order, provided a developer builds the action. Apple is also introducing skills, which combine several actions into one experience. App makers can use these tools now, with customer-facing integrations arriving as they build and ship useful actions.
Apple's own apps show the direction. New Siri AI actions are rolling out across Calendar, Files, Journal, Maps, Messages, Music, Photos, Safari, and others. Apple gives examples such as finding a coffee shop visited last week or archiving files left unopened for more than a year. For iPhoners, the interesting test will be whether a third-party app can expose similarly useful actions without requiring a carefully memorized command.
The timing is still split. Developers can start in the 27.3 betas, but Apple says the first customer-facing integrations will ship in a few months and App Store submissions open in the spring. It has not yet detailed the terms and usage policies for these experiences. Siri AI's beta also requires an Apple Intelligence-enabled device and a supported language; it is unavailable in the EU on iOS, iPadOS, and watchOS, and Apple says some server-backed features have daily limits.
I would judge this opening by the actions developers ship, not by the number of apps that announce support. A delivery status or reservation that Siri handles reliably would be more useful than another voice shortcut that merely opens an app.
