Apple is opening Siri AI to every app developer, and the move signals that Apple sees third-party integrations as central to its assistant’s future. With the iOS 27.3, iPadOS 27.3, macOS 27.3 and visionOS 27.3 betas, a new Developer Preview lets any app plug its content and actions directly into the rebuilt, conversational Siri. Until now, Apple has largely decided which kinds of apps could integrate and how.
The integration runs through App Intents, the framework Apple introduced in 2022 as a more flexible successor to SiriKit’s narrow, category-based model. What has changed is the assistant on the other end. Siri AI draws on personal context, onscreen awareness and natural language. Users can phrase a request in their own words, and the assistant carries out whatever custom action a developer has exposed, from tracking a delivery to booking a table or placing an order.
Two additions stand out. Developers can now build skills that teach Siri AI to chain several actions together for more complex requests. The assistant can also surface any entity from the Spotlight semantic index, not only the ones that fit Apple’s predefined schemas. That second change matters more than it sounds. Rigid schemas are a big reason Siri integrations have historically felt confined to a handful of app categories, such as messaging, media and to-do lists.
Apple has already built these capabilities into a long list of its own apps, including Mail, Messages, Photos, Notes, Files, Finder, Safari, Maps, Calendar and Reminders. Those apps effectively double as reference examples for developers. The company says the third-party experience will reach customers in a few months, with App Store submissions opening in the spring. However, Apple has not yet published the terms and usage policies for these integrations, so developers are being asked to build before they know the full rules.
There are other caveats. Siri AI currently supports English, French, Japanese, Korean, Portuguese and Spanish, with Traditional Chinese, Norwegian, Turkish and Vietnamese on the way. Arabic appears on neither list, which limits the feature’s near-term reach across the Middle East. It also remains unavailable in the EU on iPhone, iPad and Apple Watch, is off-limits to users under 13, and requires an Apple Intelligence-capable device.
The most telling detail sits in the fine print. Server-side features, Siri AI included, are subject to daily usage limits, and Apple says expanded access will come at a cost in the future. If talking to Siri becomes the main way people reach apps, developers will want to know whether their customers might hit a usage cap halfway through a request.
