Siri AI's Developer Preview Excludes TestFlight and the App Store, With Submissions Not Opening Until Spring

Apple opened a Siri AI Developer Preview to every developer on November 3, 2026, but nothing built against it can reach a customer yet. External TestFlight testers and App Store downloaders get none of the Siri AI functionality, even when the code ships in the build.

Apple announced the preview in a post on its developer news page. The restrictions that matter to anyone planning work sit one layer down, in documentation that PPC Land's Luis Rijo went through on November 4. Where this piece cites a limit that Apple's own post does not state, it says so.

What Apple opened on November 3

The route in is App Intents. An app marks an intent with @AppIntent(.tool) and Siri AI can call it, according to PPC Land's reading of the documentation, which says no new entitlement or separate program is needed. Apple's post gives examples such as checking a delivery, booking a reservation or placing an order.

Apple's post says the preview starts with the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas. Siri AI also runs in beta on watchOS 27.3, but PPC Land says the preview does not cover that platform.

Who can test it, and who cannot

The practical split is between a developer's own device and everyone else.

Build or user	Siri AI preview features
Development-signed build on a supported device	Yes
Internal TestFlight tester	Yes, per PPC Land
External TestFlight tester	No
App Store download	No
Xcode Simulator	Skills cannot be verified

The device needs Apple Intelligence turned on and a supported language. Apple lists English, French, Japanese, Korean, Portuguese and Spanish, with Traditional Chinese, Norwegian, Turkish and Vietnamese marked as coming. Users must be 13 or older.

Skills are SKILL.md folders with a 10,000-character cap

Apple's post says developers can write skills that teach Siri AI to combine several actions into one experience. PPC Land's summary of the documentation is more specific: each app target holds one skills bundle, and each skill is a folder containing a SKILL.md file.

The limits it reports are a name of 1 to 64 lowercase letters, digits or hyphens that must match the folder, a description of up to 1,024 characters and a body of up to 10,000. The format is a subset of the open Agent Skills standard, PPC Land wrote. Duplicate skill names produce undefined behavior. The same file shape is turning up in Cloudflare's security audit skill and in the agent tooling covered in Anthropic's agent memory study.

Skills are advisory. PPC Land reports that they cannot force deterministic behavior, because the model decides what happens in each conversation. Apple adds a Siri Integration Advisor to Xcode that reviews App Intents code, and a Siri Evaluations framework, in beta from 27.3, that scripts conversations. Because responses vary, developers are told to run each scenario repeatedly.

Daily limits with no figures, and the EU gap

Apple's post says server-side features, Siri AI included, are subject to daily usage limits that vary by feature, request complexity and system demand. It adds that expanded access "will be available for a fee in the future". No limit and no price appears in the post.

Siri AI is not available in the EU on iOS, iPadOS and watchOS. Apple says it is working with the EU on a path forward. PPC Land reports that EU Mac and Vision Pro users have had Siri AI since September 14, so an EU developer can test on a Mac but not on an iPhone.

Apple says customers get Siri AI integrations "in a few months" and that App Store submission opens "in the spring". It has not published the terms and usage policies for Siri AI experiences, and PPC Land notes Apple has not said whether requests routed through a third-party app count against a user's daily allowance.
