For years, asking Siri to do anything inside a third-party app felt like asking a hotel concierge to fix your car: polite, well meaning, not much help. Apple now says any app can plug straight into its rebuilt assistant, and it's giving developers access months before customers get it.
App Intents Get a Promotion
On November 3, Apple announced a Developer Preview that lets any developer integrate their app with Siri AI, starting with the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas. It's built on App Intents: apps expose custom actions that Siri AI carries out from natural-language requests, with Apple's examples running from "checking a delivery to booking a reservation to placing an order." Developers can also build "skills" that teach Siri AI to combine several actions into one experience.
Siri AI can now surface any entity in the Spotlight semantic index, not just the ones that fit an existing schema. Apple says the feature ships to customers "in a few months," with App Store submissions opening in the spring and terms and usage policies still to come. The caveats: it needs an Apple Intelligence-enabled device set to a supported language, it's currently unavailable in the EU on iOS, iPadOS and watchOS, and some server-side features have daily usage limits, with expanded access "available for a fee in the future."
Your App Just Became Plumbing
The bigger shift is that users may never open your app. If someone can say "reorder my usual" and Siri handles it through your intents, the assistant becomes the storefront and your app becomes infrastructure. Brands that expose clean, well-described actions will get picked. Brands that don't will simply not come up.
The part most coverage will skip is that this lives or dies on your back end. An intent that books a reservation is only as good as the API, data model and business rules behind it. Companies with structured content and tidy systems will plug in fast. Companies whose product data lives in a spreadsheet called FINAL_v7 are in for a long winter.
Agents are coming for the user interface, and this time Apple is the one sending the invitations.
