For years, asking Siri a real question felt a bit like talking to a polite intern who kept forgetting what you said two sentences ago. That era is finally ending. At WWDC 2026 on June 8, Apple confirmed that iOS 27 will let iPhone owners route their requests to outside AI assistants — and Anthropic’s Claude is one of the headline names on that list.
If you’ve been loyal to Siri out of habit rather than love, this is the update that actually gives you a choice. Here’s what’s changing, why it matters, and how it will feel day to day once iOS 27 lands this fall.
The Big Shift: Siri Is No Longer the Only Voice in the Room
Since 2024, the iPhone has had exactly one outside brain it could borrow: ChatGPT. You could hand a tricky question to OpenAI’s model through Siri, but that was the whole menu. One provider, take it or leave it.
iOS 27 tears that wall down with a new framework Apple calls Extensions. Instead of striking one exclusive deal, Apple is opening Siri — along with Writing Tools and Image Playground — to multiple third-party AI providers. Claude, ChatGPT, Google Gemini, and Grok can all plug in, and you get to decide which one answers when you ask for something heavier than “set a timer for 10 minutes.”
Think of it the way you already think about default browsers or default email apps on the iPhone. You install the AI you trust, flip a setting, and your phone starts leaning on that model across the system. For people who’ve come to prefer Claude’s writing and reasoning style, this is the first time that preference can live natively on an iPhone instead of trapped inside a separate app.
Where You’ll Actually Choose Claude
The control lives where you’d expect it: inside the Apple Intelligence & Siri section of the Settings app. Apple is adding a dedicated Extensions area, and the App Store will get its own section for these AI apps so you can find and download a provider in a couple of taps. Apple even surfaces download links right from Settings.
So the flow looks roughly like this. You grab the Claude app from the App Store, open Settings, point your Apple Intelligence features at Claude, and from then on the assistant you’ve chosen handles the requests you send its way. No jailbreak, no workaround, no copy-pasting between apps. It’s a first-class option built into the operating system.
That last point is the quiet revolution here. Plenty of people already use Claude on their iPhone — but as a destination, an app you deliberately open. Extensions makes it ambient. It becomes part of how the phone itself thinks.
Siri Itself Got a Serious Rebuild
Don’t mistake all this openness for Apple giving up on its own assistant. Far from it. The version of Siri unveiled at WWDC 2026 is the most aggressive overhaul since the assistant launched back in 2011.
The new Siri behaves much more like the chatbots you already know. Apple showed an assistant that can hold a genuine back-and-forth conversation, read what’s currently on your screen, and dig through your own messages, emails, and photos to actually answer a question rather than tossing you a list of web links. There’s a standalone Siri app with an iMessage-style interface — chat bubbles, a text field, a microphone toggle for voice, and a paperclip for attaching images and files. Conversations are saved as history and synced through iCloud.
Apple is also adding a system-wide “Search or Ask” gesture, letting you swipe down from the top to summon an AI search bar from anywhere. It’s a meaningful change to muscle memory after more than a decade of holding the side button.
Under the hood, the rebuilt Siri runs on what Apple calls its Foundation Models, which the company says were custom-built in collaboration with Google and its Gemini models. Bloomberg reported the arrangement could cost Apple around $1 billion a year, though Apple hasn’t confirmed a figure. For a company that has long sold on-device processing and in-house silicon as its edge, leaning on a rival’s models is a real philosophical shift.
So Why Would You Pick Claude Over the New Siri?
Here’s the honest answer: it depends on what you ask your phone to do.
The revamped Siri will be excellent at the things tied tightly to your device — pulling context from your calendar, your texts, your screen. That personal awareness is Apple’s home-field advantage, and no third-party model gets the same deep hooks into your data.
But for tasks where the quality of the thinking matters most — drafting a careful email, working through a thorny problem, summarizing a long document, writing code, reasoning step by step — many users have a clear favorite, and for a lot of them that’s Claude. Extensions means you no longer have to choose between Apple’s tight device integration and the model you actually trust for the hard stuff. You can lean on Siri for the local, personal things and route the heavy lifting to Claude.
It also ends the awkward situation where the iPhone effectively endorsed a single AI company. Competition tends to be good for the person holding the phone.
The Catch: Timing and Region
A few expectations worth setting before you get too excited.
First, most of the iOS 27 software lands this fall, but the fully rebuilt Siri AI is slipping to a beta later in the year rather than arriving on day one. Apple has a long, well-documented history of announcing AI features well before they’re ready for everyone, so it’s wise to treat the keynote as a preview rather than a shipping product.
Second, there’s a regional wrinkle. Some of these features may not arrive for European iPhone owners at launch, thanks to the regulatory landscape there. If you’re in the EU, check the fine print before assuming Claude-on-Siri will be waiting for you.
A developer beta is rolling out now, with a public beta expected in July and the wider release arriving alongside new iPhone hardware in the fall.
What This Means for You
If you’re an everyday Siri user, the takeaway is simple and genuinely good: you’re getting choice for the first time. You can stick with the new, far more capable Siri, or you can make Claude your default brain for the requests where reasoning and writing quality matter most — all without leaving the operating system.
The iPhone is quietly becoming a platform where you assemble your own AI experience rather than accepting a single one handed to you. Claude arriving as a built-in option is one of the clearest signs yet that the assistant on your phone is finally becoming your assistant.
When iOS 27 lands, it’s worth spending five minutes in Settings to decide who you actually want answering when you ask. For a lot of people, that conversation will end with Claude.
Frequently Asked Questions
Can I use Claude instead of Siri on my iPhone? Yes. With the Extensions system in iOS 27, you can set Claude as your preferred AI assistant across Apple Intelligence features through the Settings app. You’ll download the Claude app and select it as your provider.
When does iOS 27 with Claude support come out? Apple unveiled iOS 27 at WWDC on June 8, 2026. A public beta is expected in July, with the full release arriving in the fall alongside new iPhone hardware. The fully rebuilt Siri AI is expected in a beta later in the year.
Is the new Siri powered by Claude? No. Siri’s own engine is reportedly powered by Apple Foundation Models built in collaboration with Google’s Gemini. Claude is available as a separate, user-selectable option through Extensions, not as Siri’s underlying model.
Which AI assistants can I choose on iOS 27? Apple is opening the system to multiple providers, including Claude, ChatGPT, Google Gemini, and Grok, with more expected as the marketplace matures.
