On November 3, Apple announced on its Developer site that a new Developer Preview in the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas lets any app bring its content and actions into Siri AI through App Intents, tapping personal context, onscreen awareness and natural language. Apple also introduced skills, which teach Siri AI to combine several actions into one experience, and Siri AI can now surface any entity in the Spotlight semantic index. It is a preview only: customer rollout is a few months away and App Store submissions open in spring. Siri AI remains unavailable in the EU on iOS, iPadOS and watchOS.
Key Takeaways
- ✓Covers four platform betas: iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 (Apple Developer news)
- ✓Any app can join Siri AI via App Intents; new skills combine several actions into one request, and Siri AI can surface any Spotlight semantic-index entity, not just ones that fit an existing schema
- ✓Apple has already rolled the capabilities into 15 of its own apps, including Calendar, Files, Finder, Mail, Maps, Messages, Notes, Photos, Safari, Shortcuts and Weather
- ✓Timeline: customers get it "in a few months," App Store submissions open in spring, and Apple Intelligence Group Labs run November 4-5
- ✓Limits: Siri AI is unavailable in the EU on iOS, iPadOS and watchOS and for users under 13; server-model features have daily usage limits, with paid expanded access promised later

Background and pain point
Third-party apps used to reach Siri only through a small set of predefined schemas, so most apps could not use Siri AI's new abilities. On November 3, Apple announced on its Developer site that Siri AI is open to all developers, a key step in handing system-level agent capabilities to third parties.
How it works
Per Apple, integration still runs through App Intents: developers express app actions as AppIntent types with @Parameter inputs, and Siri AI carries them out using personal context, onscreen awareness and natural language, from checking a delivery to booking a table or placing an order. New skills teach Siri AI to chain several actions into one experience, and Siri AI can surface any entity in the Spotlight semantic index. The Verge, citing Apple's docs, reports that users need not name the app while it is in the foreground, showing a Live Activity, or being discussed with Siri AI.
Benchmarks
This is a platform opening, not a model release; Apple has published no benchmarks or success rates. The checkable numbers are four platform betas, 15 Apple apps already integrated, and App Store submissions opening in spring.
Getting started
Install a 27.3 developer beta on an Apple Intelligence device set to English, French, Japanese, Korean, Portuguese or Spanish, define intents and entities for your core actions per the new App Intents docs, then compose multi-step flows with skills. Apple Intelligence Group Labs on November 4-5 take questions. Note that Siri AI itself cannot be tested on EU iPhones for now.
