Apple lets developers plug Siri AI actions into third-party apps

Apple is opening Siri AI to third-party apps. With the iOS 27.3 developer beta released on Tuesday, November 3, developers can integrate Siri AI’s new features in “all apps”, letting the assistant use a person’s personal context, natural-language requests and on-screen awareness to complete tasks inside them. The same day, Apple shipped a watchOS 27.3 developer beta with always-on Audio Intelligence features that let Siri listen through the Apple Watch microphone to transcribe and summarize conversations.

For developers who build iOS apps, this is the moment Siri AI stops being limited to Apple’s own apps and a narrower set of hooks. The release is a Developer Preview, so the work now is integration and testing, not shipping to the general public.

What iOS 27.3 opens up for third-party apps

According to The Verge’s report on Apple’s announcement, the iOS 27.3 update lets developers connect their apps to Siri AI so the assistant can do three things when handling a request: draw on a user’s personal context, process natural-language prompts, and use on-screen awareness, meaning it can take into account what the user is currently looking at.

The update also adds a feature Apple calls app skills. Third-party developers can create app skills that combine several tasks into a single action. In practice, that gives developers a way to package a multi-step workflow inside their app as one thing Siri AI can trigger.

This is an expansion, not a first step. As 9to5Mac noted, per The Verge, Apple had previously made a smaller set of these features available to third-party developers. The Verge’s report does not detail which features were in that earlier set or name the developer framework behind the new integration.

Requests without naming the app

One change that matters for user experience is how Siri AI works out which app a request is meant for. In Apple’s developer documentation, the company says users will not have to mention an app’s name in a request while the app is in the foreground, during a Live Activity (the live-updating status cards on the Lock Screen), or during a conversation with Siri AI about the app. Apple gives this example:

“For example, a person might request a ride with a ride share app, follow updates to the app’s Live Activity while they wait for their ride to arrive, then request to move the pickup location to a different address by saying ‘Hey Siri, change my ride pickup to a new address,’”

That example shows the intended pattern: a task that starts in one app and continues through follow-up requests, with Siri AI keeping track of which app is in play.

Apple’s own apps get the same Siri AI capabilities

Apple is bringing Siri AI’s expanded capabilities to its own apps as well. The list includes Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts and Weather.

“Users can do things like find a coffee shop they visited last week or archive files that haven’t been opened in over a year,”

Apple also says users can ask Siri AI what it can do in each app, which gives people a way to discover supported actions without guessing. For third-party developers, Apple’s first-party apps set the baseline that users will compare their integrations against.

On Apple Watch, Apple’s watchOS 27 page describes the same direction. It says Siri AI, “powered by Apple Intelligence”, can “take action in apps”, with examples such as sharing flight details with family, playing a song a trainer recommended, or setting a new Activity rings goal. The page also says Siri understands personal context, for instance finding a door code for an upcoming house rental or details from a saved note, and that Siri AI is rolling out in English.

Always-on Audio Intelligence arrives in the watchOS 27.3 beta

The watchOS 27.3 developer beta adds two Audio Intelligence features that let Siri tune into the Apple Watch’s microphone:

• Live Rewind generates text transcripts of the last 15 seconds of audio the watch’s microphone detected. A double-press of the Digital Crown shows those 15 seconds as a text snippet. Users can ask Siri about the content or save it to the Siri app to revisit later.
• Siri Recap uses what Apple calls “ambient listening” to summarize conversations. When it is turned on, Apple Intelligence automatically generates a title and key points in the new Siri app after a conversation.

The Siri app referenced here is the dedicated app Apple introduced with watchOS 27, which collects a user’s Siri conversations in one place so a person can start on iPhone and continue on Apple Watch.

Feature	Platform	What it does (as reported)

Alongside these, Apple released its redesigned Health app for testing in the iOS 27.3 developer beta, with a new Insights tab summarizing heart, sleep, fitness and other data, and a For You section with personalized recommendations. The Verge also reports Apple announced expanded language support covering global English, Chinese (Simplified and Traditional), French, Japanese, Korean, Norwegian, Portuguese, Spanish, Turkish and Vietnamese.

Apple’s privacy claims for an always-listening watch

An assistant that listens around the clock raises obvious privacy questions, and Apple has published an Audio Intelligence Privacy Overview to address them. In it, Apple claims a user’s raw audio “is handled within dedicated hardware, is not saved as a file, and is not accessible to the operating system, apps, or Apple”.

On what happens to saved output, Apple says: “If you use iCloud with two-factor authentication and have a device passcode, any Siri Recap summary or Live Rewind text snippet you choose to save syncs across your devices end-to-end encrypted in the Siri app”.

These are the maker’s own statements. None of the sources describes independent verification of how the dedicated hardware handles audio, so developers and users should treat them as claims until security researchers examine the beta.

How Apple got here: a long-delayed Siri

The ability for Siri to act across apps has been a long time coming. Apple unveiled an upgraded assistant at WWDC 2024, initially targeting a spring 2025 release before pushing it to 2026, according to an AppleMagazine report from August 2025. That report described Apple’s App Intents framework, already used in Shortcuts, Spotlight and widgets, as the system that lets apps expose specific functions to Siri, and said developers behind apps such as Uber, AllTrails, Threads, Temu, Amazon, YouTube, Facebook and WhatsApp were integrating it. The Verge’s report on iOS 27.3 does not say which of those apps, if any, support the new features, or confirm that App Intents is the mechanism.

Apple executives have been open about why the work took so long. At WWDC 2025, Craig Federighi told The Verge, “When it comes to automating capabilities on devices in a reliable way, no one’s doing it really well right now,” as recounted by Gadget Hacks. Greg Joswiak explained the decision to pull the first version: “It would’ve been more disappointing to ship something that didn’t hit our quality standard, that had an error rate that we felt was unacceptable”.

Gadget Hacks also pointed to an unresolved infrastructure question: a January report from Bloomberg said the rebuilt Siri chatbot may rely heavily on a custom Google Gemini model, with Apple and Google reportedly discussing hosting it on Google’s servers. That is a report, not an Apple statement, and none of the November 3 sources addresses where Siri AI requests from third-party apps are processed.

What it means for app builders

For developers, the practical change is that Siri AI can now become a front door to an app’s functions, not just Apple’s. A few implications follow from what the sources describe:

• Context replaces explicit commands. Because users won’t need to name an app in the foreground, during a Live Activity or in an ongoing Siri AI conversation, apps that use Live Activities for ongoing tasks, such as rides, deliveries or bookings, have a clear path to follow-up voice requests.
• App skills reward well-defined workflows. Since app skills combine several tasks into one action, developers will need to decide which multi-step flows are safe and useful to expose as a single request.
• Discoverability is built in. Users can ask Siri AI what it can do in each app, so the actions a developer exposes are likely to be what users find.
• Reliability is the hard part. Apple’s own executives framed error rates as the reason for the delay. An assistant that takes actions on a user’s behalf in third-party apps raises the cost of a wrong interpretation, and nothing in the sources reports how well the new integration performs in testing.

Open questions remain. The sources do not give a public release date for iOS 27.3 or watchOS 27.3, do not say which languages third-party Siri AI integrations support beyond Apple’s note that Siri AI is rolling out in English, and do not describe any review or permission process for which actions apps can expose.

What to watch next

The next signals will come from the beta itself. Watch for developers publishing hands-on reports on app skills and on how reliably Siri AI picks the right app without being told, for which major third-party apps announce support, and for security researchers testing Apple’s claims about how Apple Watch audio is handled. A public release date for iOS 27.3 and watchOS 27.3 would mark when users, not just developers, get Siri AI acting across third-party apps.
