Siri AI is about to get a lot more useful. With the first iOS 27.3 beta, released on 3 November 2026, Apple has opened Siri AI to every app developer through a new Developer Preview, letting third-party apps plug their own actions and content straight into the reimagined assistant. For UK iPhone owners, it is the clearest sign yet that Siri could soon handle everyday tasks inside the apps you already use, from checking a delivery to booking a table.
What Apple has announced
Apple confirmed the change in a post on its Apple Developer news page, alongside the first developer betas of iOS 27.3, iPadOS 27.3, macOS 27.3, watchOS 27.3, tvOS 27.3 and visionOS 27.3.
Until now, Siri AI could only act inside third-party apps where a task fitted one of the categories Apple had defined in advance. The new Developer Preview removes that restriction. Using Apple’s App Intents framework, any app can now bring its content and actions into Siri AI, and the assistant can carry out whatever custom action a developer builds.
Apple gives examples such as checking a delivery, booking a reservation and placing an order. Because Siri AI understands natural language and what is on your screen, you can ask in your own words.
Skills: several actions in one request
The headline addition for developers is something Apple calls skills. These let a developer teach Siri AI how to combine several actions into a single experience, so one spoken request can trigger a chain of steps rather than a string of separate commands.
Apple has also widened what Siri AI can find. It can now surface any item in the Spotlight semantic index, not just content that fits an existing schema, which should make app content much easier to discover by voice.
New Siri AI actions in Apple’s own apps
While third-party integrations will take time, Apple is already rolling out the new capabilities across its own apps. According to Apple, Siri AI gains new actions in Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts and Weather.
MacRumors reports that, in Mail, Siri can now unsubscribe you from mailing lists and undo recently sent messages. In Safari, it can clear browsing history, manage tabs and windows, save articles to your Reading List and close duplicate tabs. In Files, it can tidy up content and delete files you have not opened for a set period.
Apple is also expanding Siri AI’s language support to Traditional Chinese, Norwegian, Turkish and Vietnamese, adding to English, French, Japanese, Korean, Portuguese and Spanish.
What else is in the iOS 27.3 beta?
The first beta also brings back the redesigned Health app, with new Insights and Longevity tabs, while Safari gains an optional Vertical Tabs layout and an Adaptive Dark Mode for websites without their own dark design.
When will UK users get it?
There are two timelines to keep in mind.
The iOS 27.3 update itself
The iOS 27.3 beta is currently for developers only. 9to5Mac reports that Apple signals the update, including the new Health app, will ship to everyone before the end of the year. Like other iOS updates, it will be free.
Third-party Siri AI integrations
The bigger wait is for app integrations. Apple says this preview gives developers early access “before first shipping to customers in a few months”, and that App Store submissions for these experiences will open in the spring. In practice, that means you should not expect your favourite apps to work with Siri AI in this way until 2027.
Is Siri AI available in the UK?
Yes. Apple’s restrictions on Siri AI apply to iPhone, iPad and Apple Watch in the EU, and to Apple Accounts in mainland China, so neither affects the UK. Siri AI is still labelled as a beta and works in English when your device and Siri language match. According to Apple Support, you will need an Apple Intelligence-capable device, such as an iPhone 15 Pro or later, any iPhone 16 model or later, iPhone Air or iPhone Duo. You can switch it on in Settings under Siri, then Try Siri AI (Beta), though there may be a waitlist.
Will it cost anything?
Siri AI is currently included at no extra cost, but Apple notes that features relying on its server-side models, including Siri AI, are subject to daily usage limits. It adds that “expanded access to such features will be available for a fee in the future”. Apple has not announced a UK price for that expanded access yet.
Why this matters
Opening Siri AI to all developers is arguably the biggest step in Apple’s assistant reboot so far. An assistant is only as useful as the apps it can control. If developers embrace App Intents and skills, everyday jobs such as reordering a takeaway, tracking a parcel or managing a booking could become a single spoken request.
The catch is timing. With App Store submissions not opening until spring, the 2026 Christmas period will come and go before most third-party Siri AI features arrive. UK iPhone users can try the new actions in Apple’s own apps once iOS 27.3 lands.
