Right now, if Siri cannot answer something, it passes the question to ChatGPT. That has been the only option since iOS 18.2 in 2024. iOS 27 is expected to change that, and the shift is bigger than it sounds on the surface.
According to Bloomberg’s Mark Gurman, Apple is building a new Extensions system that would let third-party AI chatbots integrate directly with Siri. ChatGPT keeps its spot.
But Claude, Gemini, and potentially other AI services join alongside it, each one available to handle queries from inside the same Siri interface you already use every day. The formal announcement is expected at WWDC on June 8, 2026.
TL;DR: iOS 27 is expected to introduce a Siri Extensions system that lets you choose which AI chatbot handles your queries, with Claude, Gemini, and ChatGPT all configurable from inside Settings. OpenAI loses its exclusive position. The feature requires iPhone 15 Pro or newer for Apple Intelligence and is expected to be announced at WWDC on June 8, 2026, with a public release in September.
What the Extensions system actually does
The setup works through a new panel inside the Apple Intelligence and Siri section of the Settings app. You install a supported AI chatbot from the App Store and it becomes available as an Extension.
From there, you configure which services are active and, based on Gurman’s reporting, potentially route different types of queries to different providers.
In theory, you could send a research question to Gemini, a coding question to Claude, and a creative writing prompt to ChatGPT, all from the same Siri interface without switching apps.
That is how the intent has been described. How smooth it feels in practice depends entirely on how Apple implements the handoff, which will not be clear until the first betas land in June.
Apple is also developing a dedicated App Store section for AI Extensions, functioning like a marketplace for AI integrations. Companies would need to update their apps to support the standard before appearing in that panel.
Apple would reportedly take a cut of any AI subscriptions purchased through the App Store, which gives the company a financial reason to keep the system open rather than reverting to a single exclusive partner.
Why this ends something important
OpenAI has had exclusive access to Siri since iOS 18.2. That exclusivity meant iPhone users who preferred Claude or Gemini had no native path to reach them through Siri, even with those apps already installed. If you wanted Claude for a specific task, you opened the Claude app separately. Siri and your preferred AI lived in different windows.
There is a working workaround that lets you use ChatGPT with Siri without Apple Intelligence using the Shortcuts app, but it requires manual setup and only works with ChatGPT.
The Extensions system, if it ships as described, would make that kind of friction unnecessary for any supported chatbot.
The shift also matters for the AI market more broadly. Being available inside Siri on over a billion active iPhones is a meaningful distribution advantage. Apple opening that slot to multiple providers changes the competitive dynamics significantly, for users and for AI companies alike.
The Gemini situation is two things at once
Gemini’s position in iOS 27 is worth keeping straight because it operates on two separate levels simultaneously.
On the back end, Apple signed a reported $1 billion per year partnership with Google in January 2026. Under that deal, a custom version of Gemini’s models powers the rebuilt Siri chatbot itself, the one with conversation history and the new standalone app.
Google Cloud chief Thomas Kurian confirmed this publicly at Google Cloud Next in April 2026. No Gemini branding is visible to users. From the iPhone’s perspective, it just looks like Siri.
On the front end, the Gemini app would also be available as a separately installable Extension through the same system as Claude and ChatGPT. So Gemini would be both the engine underneath Siri and a directly choosable option for users who prefer it. If you want to start using Gemini on your iPhone now while this update is still months away, the app is already available in the App Store.
What is not confirmed yet
Apple has not officially announced the Extensions system. Everything here comes from Gurman’s Bloomberg reporting, which has a strong track record on Apple software features but remains pre-announcement.
Apple’s plans can shift between reporting and reveal, and the feature could arrive in a narrower form or be pushed to a later update.
Open questions remain about how the experience actually works. Can you set a default Extension for all queries, or only configure preferences by type?
Does Siri hand off cleanly and return the result inside its own interface, or does it open the third-party app? How does this interact with the new standalone Siri app also reportedly coming in iOS 27? None of that is confirmed yet.
The requirement to have the chatbot app installed is also worth noting. Claude would not appear as an option unless you already have the Anthropic app.
Gemini would not appear unless you have Google’s app. It is not a built-in menu of every AI service. It is an extension of what you already have installed, which makes the App Store marketplace piece of this more meaningful than it first sounds.
The part worth watching after WWDC
The announced version of a feature and the shipped version often differ in the details. Apple previewed personal context and on-screen awareness for Siri at WWDC 2024.
Two years later, those features still have not shipped in their originally described form. The Extensions system could launch in a more limited state than Gurman’s reporting suggests, or certain providers could be excluded at launch pending technical review.
What is harder to walk back is the direction. Apple opening Siri to competing AI providers is a structural shift, not a feature that quietly disappears in a point release. Whether the experience is clean enough to use regularly is a separate question. That answer arrives with the first iOS 27 beta on June 8.
