iOS 27 is out, but plenty of people who just updated are opening Settings and finding no trace of the new Siri app or the smarter voice assistant Apple demoed on stage. That is because Siri AI does not turn on automatically. You have to join a waitlist first.
Siri AI Only Runs on iPhone 15 Pro and Newer
Apple Intelligence compatibility is the dividing line here. If your iPhone cannot run Apple Intelligence, it cannot run Siri AI, regardless of whether iOS 27 installed cleanly. Apple also requires your device language and Siri language to be set to the same supported language, which is currently English, and your Apple Account to be in an eligible region.
The full list of compatible iPhone models is below.
| Siri AI Compatible iPhones |
|---|
| iPhone 18 Pro |
| iPhone 18 Pro Max |
| iPhone Duo |
| iPhone 17e |
| iPhone 17 |
| iPhone 17 Pro |
| iPhone 17 Pro Max |
| iPhone Air |
| iPhone 16e |
| iPhone 16 |
| iPhone 16 Plus |
| iPhone 16 Pro |
| iPhone 16 Pro Max |
| iPhone 15 Pro |
| iPhone 15 Pro Max |
Signing Up Takes Four Taps in Settings
Getting on the waitlist does not require an Apple Account form or a separate app download. It happens straight from the Settings app.
- Open the Settings app on your iPhone
- Tap on the Siri menu
- Tap Try Siri AI (Beta)
- Follow the on-screen prompts
If the option never appears after you tap through, our guide to Siri AI not working in iOS 27 covers the usual causes.
Wait Times Range From Minutes to Several Days
Apple says wait times vary, and some users get access within a few minutes of signing up while others report waiting hours or even days before their iPhone unlocks the feature. Siri AI downloads automatically when your wait is over, and the Siri app appears on your device at that point.
Siri AI Adds Screen Awareness and ChatGPT Style Answers
Classic Siri has always handled basic requests like setting a timer or checking the weather, but it has struggled with anything more complex for years. Siri AI is built to fix that gap and behaves closer to a ChatGPT style assistant that can answer most questions directly, pull from your personal information stored on the iPhone, read what is currently on your screen, and take actions inside apps that support it.
Once it is active, there are three ways to bring it up:
- Swipe down on the iPhone’s Dynamic Island
- Press and hold the iPhone’s side button
- Open the dedicated Siri app directly
Voice Customization Is Limited to Newer iPhones
A handful of models also let you adjust Siri AI’s pace and expressivity, changing how fast and how animated the voice sounds when it responds.
| iPhones With Pace and Expressivity Controls |
|---|
| iPhone 18 Pro |
| iPhone 18 Pro Max |
| iPhone Duo |
| iPhone 17 Pro |
| iPhone 17 Pro Max |
| iPhone Air |
Siri AI Only Supports English for Now
Language support is narrow at launch because Siri AI works in English only, and Apple has said French, Japanese, Korean, Portuguese, and Spanish are coming, with those languages already showing up in the iOS 27.2 beta.
Apple has also confirmed Siri AI carries unspecified daily usage limits, with expanded access promised for select iCloud+ plans down the line. In the European Union, Siri AI is not available on iOS 27, iPadOS 27, or watchOS 27, as Apple remains in a regulatory dispute with the European Commission. Apple says it does work on macOS 27 Golden Gate and visionOS 27 in the EU when the device and Siri language are both English.
Apple still labels Siri AI as a beta feature, even though iOS 27 itself has already left beta behind.
