Apple’s AI plans for iOS 27 are starting to look much bigger than a routine Siri update, and the latest report points to a major shift in how the assistant works across the iPhone, iPad, and Mac. If this leak is accurate, Apple is preparing an all-new Siri app that works more like ChatGPT, Gemini, and Claude, while also opening the door to third-party AI tools through a new “Extensions” feature.
In his latest Power On newsletter, Bloomberg’s Mark Gurman said Apple is working on a Siri app for iOS 27, iPadOS 27, and macOS 27.

The reported app would let users talk to Siri by voice or text, check past conversations, and use the assistant in a more app-like interface instead of relying only on the current system-level experience. That alone would be a notable change, but the bigger part of the report is what Apple seems to be planning around Extensions.
Siri Extensions could turn Siri into an AI hub
According to Gurman, Apple is testing a feature that lets outside AI services plug into Siri and other system features. That would move Siri beyond its current ChatGPT tie-in and give users more choice inside Apple’s ecosystem.
“Extensions allow agents from installed apps to work with Siri, the Siri app and other features on your devices.”
Mark Gurman said this line appears in fine print inside Settings on an internal pre-release version of iOS 27.
That wording matters because it suggests Apple is not just adding another chatbot option. It is building a broader AI layer that lets “agents from installed apps” work across the system. Gurman also said the App Store will get a dedicated Extensions section, which he described as “a marketplace of sorts for third-party AI integrations.”
If Apple follows through, Siri in iOS 27 will feel less like a limited assistant and more like a central AI app with chat history, voice and text support, and deeper third party access. The big unanswered question is device support, because Apple still has not made clear whether this new Siri experience will require Apple Intelligence hardware such as the iPhone 15 Pro or newer.
