Quick Answer
Apple has opened Siri AI to third-party apps through a developer preview in the iOS 27.3 family of betas. Developers can connect app content and actions using App Intents, including custom actions and multi-step skills. The preview is not a customer launch, and feature access has limits. Users should expect initial app experiences only after Apple accepts submissions in spring 2027.

What did Apple open to third-party apps in iOS 27.3?
Apple opened a developer preview that lets any developer integrate an app directly with Siri AI. The preview arrived with the iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3 betas on November 3, 2026. Apple’s developer announcement says the system uses App Intents to bring an app’s content and actions into Siri AI.
Siri AI third-party app support matters because the assistant can move beyond a fixed set of Apple services and perform tasks defined by individual app developers. Apple says those integrations can use personal-context understanding, onscreen awareness, and natural-language requests. The developer preview does not mean every app can use Siri AI today, because developers still need to build, test, and submit their experiences.
The practical change is a broader path for app makers to define what Siri AI can do inside their services. Apple has separately expanded Siri AI language support, but Siri AI language availability is a different development from this new third-party app framework.
How will Siri AI work with third-party apps?
Siri AI will work with third-party apps through App Intents, Apple’s framework for exposing app actions and content to system experiences. Apple says developers can make their content and actions available directly in Siri AI, allowing the assistant to interpret a natural-language request and connect it to an app capability.
Siri AI can also surface entities from an app through the Spotlight semantic index. Apple says the developer preview expands this capability beyond entities that match an existing schema, which gives developers more flexibility in how app-specific items can appear in Siri AI. An entity can be a meaningful app item, such as a delivery, reservation, product, or saved record, depending on how the developer designs the integration.
The limitation is that Siri AI will only understand the actions and entities an app developer deliberately exposes. A broad conversational request does not automatically give Siri AI unrestricted control over every feature in an installed app. Users should treat early integrations as app-specific features whose usefulness will vary with each developer’s implementation.
What custom actions and skills can developers build?
Siri AI developers can build custom actions for tasks such as checking a delivery, booking a reservation, or placing an order. Apple listed those three examples in its November 3 announcement, showing that the framework is intended for practical requests that cross from a voice or typed prompt into an app workflow.
Siri AI skills support more complex requests by letting developers teach the assistant how to combine several actions into one experience. Apple describes skills as a way to handle multi-step work, rather than requiring a user to make a separate request for each individual app action. Independent coverage of the developer materials also describes the new skills system as a mechanism for advanced app workflows. Details of the Siri AI skills preview outline that broader developer direction.
The most important limit is that a skill’s quality depends on the developer’s design and the app data available for the request. A delivery app can only check a delivery that its service recognizes, and a reservation app can only complete options the service supports. Users should review the final details of an order, booking, or other consequential request before confirming it.
Which Apple software versions include the Siri AI preview?
Siri AI third-party app development is available in beta through iOS 27.3, iPadOS 27.3, macOS 27.3, watchOS 27.3, and visionOS 27.3. Apple describes the current release as a developer preview, which means the framework is available for development and testing before its planned customer launch.
The software list matters because developers can prepare experiences across Apple’s major device categories instead of designing only for the iPhone. A developer can decide which devices and app capabilities make sense for an integration. A restaurant booking action, for example, may be useful on an iPhone, Apple Watch, iPad, or Mac, but each app maker controls where its experience is offered.
Siri AI is also subject to server-side daily limits during the beta. Apple says those limits can vary by demand, request complexity, and policy. The practical response is to expect occasional availability constraints while the feature remains in preview, rather than assuming every request will work consistently during the beta period.
| Part of the rollout | Current status | What it means for users |
|---|---|---|
| Developer preview | Available in the iOS 27.3 software family | Developers can build and test Siri AI app experiences. |
| Custom actions | Supported through App Intents | Apps can define tasks such as delivery checks, reservations, and orders. |
| Skills | Introduced for complex requests | Developers can combine several actions into one workflow. |
| Customer launch | Planned in a few months | Public availability has not started yet. |
| App Store submissions | Planned for spring 2027 | Approved third-party experiences should follow Apple’s review process. |
Who can use Siri AI third-party app features?
Siri AI third-party app features require an Apple Intelligence-capable device, a supported language, and an eligible Apple Account region. Apple lists iPhone 15 Pro models and later, iPhone 16 models and later, iPhone Air, and iPhone Duo among the supported hardware. Apple’s Siri AI availability page provides the current device, language, and region requirements.
Siri AI is currently unavailable in the European Union on iOS, iPadOS, and watchOS, according to Apple. Apple also says Siri AI is unavailable to users under 13. Those restrictions mean an eligible device alone does not guarantee access, because account region, age eligibility, and supported language also affect whether the feature is offered.
The most sensible approach is to check Siri AI availability before expecting a third-party integration to appear. Users who already use connected AI tools should apply the same caution to permissions and account access that they use with services such as connected app integrations, particularly when an app request involves personal records, purchases, or reservations.
When will Siri AI third-party apps reach customers?
Siri AI third-party app experiences are expected to reach customers in a few months, but Apple has not provided a specific public launch date. Apple says the current developer preview comes ahead of the customer release, while App Store submissions for Siri AI experiences will open in spring 2027.
The staggered schedule gives developers time to build the App Intents, custom actions, and skills required for their apps. It also means the public launch and the arrival of individual App Store experiences are separate milestones. A customer launch can make the platform available before every major app has a finished integration.
Siri AI third-party app availability will therefore likely vary by developer and app category. Users should wait for an app’s own release notes or App Store listing to confirm support rather than assuming a favorite service will be available when the Siri AI customer launch begins. Apple has not identified which third-party apps will be ready first.
What should users expect from early Siri AI app integrations?
Siri AI app integrations should make supported app requests easier to express in ordinary language, but early experiences will have practical limits. Apple says server-side features have daily limits that can change with demand, complexity, and policy. A request that works at one time may not be available without limits during the beta.
Siri AI will also depend on what a developer has connected through App Intents and the information an app can recognize. The framework can improve access to an app’s existing functions, but it does not guarantee that every app feature, account type, or request will work through Siri AI. Users should continue using an app directly when a request requires detailed review or when Siri AI cannot complete it.
Siri AI integrations may become especially useful for productivity software as Apple expands its own AI tools. Apple’s work on AI assistants in office apps shows the same broader direction: using AI to reach existing content and actions more quickly. The practical measure of success will be whether individual integrations save steps without making important tasks harder to verify.
