Have you ever felt like "even after talking to Siri, you end up having to open the app yourself"? On November 3, 2026 (US time), Apple made a move to change that. This article breaks down what has been opened up, when it becomes available, and what it means for users and developers in Japan.
Apple has opened up to all developers the system that connects the revamped voice assistant "Siri AI" with third-party (non-Apple) apps. As reported by ITmedia, here is what happened.
The developer preview is included in the beta versions of iOS 27.3, iPadOS 27.3, macOS 27.3, and visionOS 27.3, all released on the same day.
General users are expected to gain access a few months from now. App Store submissions for Siri AI-compatible apps will begin in spring 2027.
Siri AI itself was announced at WWDC (Apple's developer conference) on June 8, 2026. According to Skift, the rebuilt Siri is said to be capable of understanding personal context, performing in-app actions, recognizing on-screen content, and answering questions using world knowledge. This latest development extends those capabilities to third-party apps.
At the heart of the integration is Apple's "App Intents" framework (a toolkit for development). It is the mechanism through which an app tells Siri: "Here are the actions and data I offer."
By implementing this, Siri AI becomes able to directly use an app's content and operations. Personal context, on-screen content, and understanding of natural phrasing are also brought into play.
The newly added "Skills" is a system that chains multiple actions together into a single request. For example, you might say something like "Make a reservation and add it to my calendar too."
In addition, information from Spotlight's (iPhone's search feature) "semantic index" becomes accessible from Siri AI as well. A key feature is that it is no longer confined to strictly structured information.
The examples Apple cites include checking delivery status, making restaurant reservations, and placing product orders — all doable by voice, without opening an app.
New Siri AI features are also coming to Apple's own Calendar, Mail, Maps, Messages, Photos, and Safari.
Highlighted use cases include finding a coffee shop you visited last week, and organizing files you haven't opened in over a year.
There are conditions for using Siri AI. First, you need a device that supports Apple Intelligence. Users under the age of 13 are not eligible.
Supported languages include Japanese among 6 languages total. However, some features may not be available depending on region or language.
Features that use server-side AI models have a daily usage limit. Apple plans to eventually allow users to pay to expand that limit.
Regional differences are also worth noting. According to a developer-focused explainer, consumer-facing Siri AI features will not be available at launch in the EU and China. However, developer APIs are said to be accessible.
Another explainer notes that the EU delay is related to the Digital Markets Act (DMA).
The previous system connecting Siri with apps was called "SiriKit." However, according to an explainer from development firm Scand, SiriKit was deprecated at WWDC 2026.
The same article estimates that SiriKit will be fully removed from the SDK around 2028–2029 — though it notes this is a technical deadline, separate from any business-side deadline.
The earlier explainer points out that App Intents has become the sole pathway through which the new Siri reaches apps. Apps that do not support it will become invisible to the new Siri.
| Item | Legacy SiriKit | App Intents |
|---|---|---|
| Status | Deprecated (for legacy use) | Integration method for new Siri AI |
| Access to new Siri experience | Limited | Available |
| Key added features | None | Streaming responses, multi-turn conversations, understanding of on-screen elements |
According to Scand's article, App Intents 2.0 adds streaming responses that show progress incrementally, the ability to answer follow-up questions in a conversation, and a mechanism for conveying on-screen elements to Siri.
Android has a similar system called App Actions. Teams supporting both operating systems will reportedly need to align the functionality of both features.
Since Japanese is supported, this change is relevant to iPhone users in Japan as well. However, the timeline for availability in Japan and which apps will support it remain unclear.
Imagine this: you're at a train station on a business trip, hands full of luggage, and you simply ask, "When will the package I just ordered arrive?" — and get an answer right away. No need to search for the app.
For companies operating restaurant reservation apps, Siri becomes a new entry point for bookings. Picture someone saying in the evening, "Get me a table for two near the station tonight."
For e-commerce operators, there is a possibility that purchases made without ever opening the app will increase. Without App Intents support, those customers may simply not choose your app.
On the other hand, Skift, which covers the travel industry, points out that Siri cannot yet book travel. Processing reservations and changes requires travel companies to connect their own systems.
In other words, Siri won't automatically handle everything. The experience will depend on how well each app implements the integration.
Q1. Can I use the new Siri AI to operate apps right now?
A. No. What was released is a developer beta. General users are expected to receive it a few months from now.
Q2. Can it be used in Japanese?
A. Siri AI supports 6 languages, including Japanese. However, some features may not be available depending on region or language.
Q3. Which iPhones are supported?
A. A device that supports Apple Intelligence is required. Users under the age of 13 are not eligible.
Q4. What should developers prepare?
A. Review your app's App Intents support status, and if you are using SiriKit, plan your migration to App Intents. App Store submissions for Siri AI-compatible apps begin in spring 2027.
Q5. Is usage unlimited?
A. Features that use server-side AI models have a daily usage limit. Apple plans to eventually allow users to pay to expand that limit.
Developers should start by checking whether their app's features can be exposed via App Intents. Users, stay tuned as more Siri-compatible apps become available.
