Apple Adds Claude as an iPhone AI Option: What iOS 27 Extensions Mean for You
Key takeaways
- At its WWDC 2026 keynote on June 8, Apple announced a new "Extensions" system that lets iPhone owners choose a third-party AI assistant, including Claude, ChatGPT, Gemini, or Grok, to power Siri and other built-in features.
- This is the first time Apple has offered Claude as a built-in option on the iPhone, ending the era when ChatGPT was the only outside AI tied into Siri.
- The features arrive in iOS 27, iPadOS 27, and macOS 27, with a developer test version now and a full public release expected in September 2026 alongside new iPhones.
Apple held its annual Worldwide Developers Conference (WWDC) keynote on Monday, June 8, 2026, and the headline for everyday users is choice. For the first time, your iPhone will let you pick which artificial intelligence assistant answers your questions and helps with everyday tasks. Here is a simple rundown of what was announced and what it means for you.
What Apple announced
Apple introduced a feature called Extensions as part of its next software updates: iOS 27 for iPhone, iPadOS 27 for iPad, and macOS 27 for Mac. Extensions lets you connect an outside AI app to Apple's own tools, so the assistant you trust can answer through your phone instead of Apple's default.
The AI options Apple confirmed or tested include Anthropic's Claude, OpenAI's ChatGPT, Google's Gemini, and xAI's Grok. Apple has said Claude and Gemini are among the first partners alongside the ChatGPT integration that has been part of the iPhone since 2024.
What "Extensions" actually means
Think of it like choosing your default web browser or email app. Until now, Siri could only hand certain questions to ChatGPT. With Extensions, you can set a different AI as your preferred helper, and it works across several Apple features, not just Siri. Those features include Siri itself, Writing Tools for drafting and editing text, and Image Playground for creating pictures.
This is separate from a related change: Apple's rebuilt Siri is widely reported to use Google's Gemini technology behind the scenes. Apple has not officially named the company powering Siri's core, so treat that detail as reporting rather than a confirmed fact.
How to choose Claude or another AI on your iPhone
Based on what Apple has shown, the process will be simple once the software is released. You will:
- Download the AI app you want, such as Claude or Gemini, from the App Store. Apple plans a dedicated Extensions section in the App Store to make these easy to find.
- Open Settings and go to the Apple Intelligence and Siri section.
- Select your preferred AI provider from the list of installed apps.
You will still be able to keep Siri as the default, or turn off Siri and Apple Intelligence entirely if you prefer not to use these features at all.
When can you get it, and which iPhones work?
A developer test version arrived on June 8, a public beta is expected in July, and the finished software is expected to launch in September 2026, around the time Apple typically releases new iPhones. Testing software early is not recommended on a phone you rely on for daily use.
The basic iOS 27 update is expected to support iPhone 11 and newer. However, the advanced AI features, including the new Siri and Extensions, require a more recent model, roughly iPhone 15 Pro and later, and the newest Siri voices require Apple's latest Pro phones. If you are in the European Union, note that some of these AI features may not be available at launch due to regional rules.
What this means for everyday users
The practical upshot is flexibility. If you already use and trust a particular AI, you can have it answer through your phone rather than learning a new assistant. People who prefer not to change anything can simply stick with Siri. As with most Apple previews, the most useful test is whether these features feel reliable once they ship in the fall, so there is no rush to act today.
Frequently asked questions
Can I use Claude on my iPhone now?
Not yet as a built-in option. Apple announced Claude support through the new Extensions system at WWDC on June 8, 2026, but the feature is expected to reach the public with iOS 27 in September 2026. You can already download the Claude app from the App Store to use on its own.
What is the difference between Siri and AI Extensions?
Siri is Apple's own voice assistant. AI Extensions is a new system that lets you connect a third-party assistant, such as Claude, ChatGPT, or Gemini, to power Apple features like Siri, Writing Tools, and Image Playground. Extensions gives you a choice of which AI does the work.
Is the new Siri powered by Google Gemini?
Multiple reports say Apple's rebuilt Siri uses Google's Gemini technology behind the scenes, but Apple has not officially confirmed which company powers it. The Gemini detail should be treated as reporting until Apple states it directly.
Which iPhones support iOS 27 and the new AI features?
The general iOS 27 update is expected to support iPhone 11 and newer. The advanced AI features, including the rebuilt Siri and Extensions, require a more recent model, roughly iPhone 15 Pro and later, while the newest Siri voices need Apple's latest Pro iPhones.
Is choosing a different AI assistant free?
Setting a preferred AI in Settings is part of the software. However, some AI apps offer paid plans for advanced features, so any subscription cost depends on the assistant you choose and the plan you pick within that app.
Does this replace ChatGPT on the iPhone?
No. ChatGPT remains an option. The change is that ChatGPT is no longer the only outside AI tied into Apple's features. You can now choose ChatGPT, Claude, Gemini, or another supported assistant.
When is iOS 27 coming out?
A developer beta became available on June 8, 2026, a public beta is expected in July, and the full public release is expected in September 2026, around the launch of Apple's next iPhones.
