iOS 27 arrived on September 14, and its headline feature is not a redesign or a camera trick. It is Siri AI, a rebuilt Siri powered by Apple Intelligence that Apple describes as conversational, aware of what is on your screen, and able to work with your personal context across messages, email, and photos. It is still labeled a beta, and it does not run on every iPhone that can install iOS 27. Here is the practical guide: who gets it, how to switch it on, and what is actually worth trying.
Which iPhones get Siri AI
The short version: you need an Apple Intelligence-capable iPhone. That means the iPhone 15 Pro and 15 Pro Max, every iPhone 16 model (including the 16e), every iPhone 17 model (including the 17e), the iPhone Air, the iPhone 18 Pro and Pro Max, and the iPhone Duo when it goes on sale October 23. The standard iPhone 15 and 15 Plus are out, and so is everything older.
Note the split: iOS 27 itself installs on phones as old as the iPhone 11 and the second-generation iPhone SE, but those models get the new design and speed improvements without the new assistant. On iPad, Siri AI needs an iPad mini with the A17 Pro or any iPad with an M1 chip or later. On Mac, it needs an M1 or later chip (or a MacBook Neo with the A18 Pro) running macOS 27. Every Vision Pro is supported.
One more tier to know about: the new expressive voices, which let you adjust Siri’s pace and tone, need the AFM Core Advanced on-device model, found in the iPhone Air, the iPhone 17 Pro models, and the iPhone 18 Pro models. And Siri AI is English-only for now, though iOS 27.2 is already testing Siri in five more languages.
How to turn Siri AI on
Siri AI is opt-in. After updating, iOS 27 shows a Settings notification for “Optimize Search and Siri,” which enables on-device learning from your content. Head to Settings, then Siri, and make sure your device language and Siri language are set to the same supported language. Availability varies by region: because of EU digital-markets rules, Apple is not shipping Siri AI on iOS and iPadOS in the European Union for now, though it is available there on macOS 27 and visionOS 27. It is also not available to users under 13.
Still on iOS 26? Here is how to update safely first.
11 things to try first
1. Ask about a message you half-remember. This is the feature that sells the whole thing: “What did Ananya send me about Saturday?” Siri AI can search your messages and emails for content, not just contact names.
2. Find a photo by describing it. “Show me the receipt from last Tuesday” or “the photo of the whiteboard from the meeting.” Siri AI searches your photo library by content and context.
3. Use what is on your screen. Looking at a restaurant listing? Ask Siri to add it to your contacts, or to text the address to someone. On-screen awareness means you stop copy-pasting between apps.
4. Chain a multi-step request. Ask Siri to do something that crosses apps, like pulling a flight detail from an email and adding it to your calendar. Third-party apps are joining in through Apple’s App Intents framework; early examples include Flighty and Gentler Streak, which Siri can work with without opening the app.
5. Keep the conversation going. Siri AI handles natural back-and-forth now, so follow-up questions (“and what about the return leg?”) work without restating the whole request.
6. Revisit old conversations. Siri AI gets a dedicated app where you can look back through previous chats, which is genuinely useful for anything you asked it to research.
7. Let it draft in your voice. Siri AI can mimic how you write to individual contacts when drafting emails and messages, which beats the generic AI-polite tone.
8. Let it proofread everything. Apple Intelligence now proofreads as you type across the system, including in most third-party apps. It is subtle until you notice the typos that stopped happening.
9. Ask open-ended questions. With broader world knowledge built in, Siri AI handles the kind of general questions the old Siri would have punted to a web search.
10. Try Visual Intelligence. Point the camera at something and ask about it. The visual features are part of the same Siri AI package.
11. Tune the voice. If you have a supported model, try the expressive voice settings and adjust pace and tone. It is a small thing that makes the assistant feel less like a robot reading a script.
What it will not do yet
Set expectations honestly. Siri AI is an English-only beta, and results vary with your mailbox, your message history, your language settings, and whether the apps you use have added support. Features roll out gradually, and Apple is clear that this is a beta, not a finished product.
If you hate it, there is a way back: one user reports that turning Siri off in Settings, turning it back on, and choosing classic Siri restores the old assistant. It is one user’s account, not a guaranteed path on every iPhone, but the option appears to exist.
The privacy setup worth a minute
The personal-context features only work because Siri AI learns from your content, so check the “Optimize Search and Siri” toggle and know what it does: the learning happens on the device itself, and heavier requests go to Apple’s Private Cloud Compute servers, which Apple says it cannot access. If that trade still feels like too much, the toggle is yours to switch off.
Siri AI is also spreading beyond the phone: Apple’s Welcome Home event today introduced three Siri AI devices for the home. And if the new assistant is eating your storage, here are seven ways to free space without deleting a single photo.
