You updated to iOS 27, opened Siri and nothing changed. That is not a bug. Apple’s rebuilt Siri AI does not switch on automatically after the update. You have to ask for access, and Apple lets people in gradually. This guide explains how to get Siri AI, which devices are supported, what the waitlist looks like in practice and what to try if the new Siri still does not show up.
What Is Siri AI in iOS 27?
Siri AI is Apple’s rebuilt conversational assistant. Instead of matching your words to a fixed list of commands, it can hold a multi-turn conversation, keep context during a session, search across your Mail, Messages and Photos, take actions inside apps and answer general questions using live web data. It also comes with a dedicated Siri app.
Reports around the launch say the underlying models were built with Google’s Gemini models, with processing split between your device and Apple’s Private Cloud Compute. In simple terms, most of the thinking happens on Apple’s own infrastructure, not as a live hand-off to Google for every request.
It is worth setting expectations early. Siri AI is designed around your personal data and your Apple devices. It is not meant to replace a general chatbot. If you want a broader comparison of the big assistants, read our ChatGPT vs Claude vs Gemini comparison.
Which Devices Support Siri AI?
iOS 27 installs on iPhone 11 and newer, but that does not mean every one of those phones gets Siri AI. Siri AI needs hardware that supports Apple Intelligence.
- iPhone: iPhone 15 Pro and newer.
- iPad: a model with an M-series chip or an A17 Pro chip or better.
- Mac: any Apple Silicon Mac with 12GB of RAM or more, running macOS 27 Golden Gate.
Some extras are limited to the newest phones. For example, the Siri custom voice option is reported to need an iPhone 17 Air or better. If you own an older iPhone, you can still update to iOS 27, but the new Siri will not be available on it.
Where Is Siri AI Available?
At launch, Siri AI is available in English only. It is not available to users in the EU, and it remains on hold in China. If your device region or language is set outside these conditions, the option to join will not appear or will not work.
More languages are expected in the coming weeks, according to launch coverage, but Apple has not promised a date for every market. Check your Apple Intelligence and Siri settings after each update.
How to Get Siri AI: Step by Step
Follow these steps on your iPhone. The wording in Settings can differ slightly between builds, so look for the Siri or Apple Intelligence and Siri menu.
- Update your device to iOS 27 (or iPadOS 27 or macOS 27 on iPad and Mac). Go to Settings, then General, then Software Update.
- Make sure your device language and Siri language are set to English.
- Open Settings and tap Siri (on some builds this appears as Apple Intelligence and Siri).
- Turn on Apple Intelligence if it is off. The required AI models download in the background, which can take a while and needs free storage space.
- Tap Try Siri AI (Beta) and follow the prompts to join the waitlist.
- Wait for the notification. When access is granted, your device tells you and the Siri app appears automatically.
If you already joined the waitlist on one Apple device, you do not need to repeat the process on your other compatible devices. Once you are approved on one, Siri AI is available across your compatible devices.
How Long Is the Siri AI Waitlist?
There is no fixed answer. Reports since launch describe some people getting access within minutes, while others waited hours or even days. During the beta period, waits ran up to a week for some users. Apple has not confirmed whether the timeline will shrink now that iOS 27 is public.
Joining the waitlist also does not guarantee instant access. People who used Siri AI during the beta were told they may need to rejoin the waitlist on the public release.
How to Use Siri AI Once You Have Access
You can talk or type to Siri AI in three ways: swipe down on the Dynamic Island, press and hold the side button, or open the new Siri app. A few practical ideas to test first:
- Ask it to find something across your Mail, Messages and Photos, such as a flight confirmation or a photo from a specific trip.
- Give it a follow-up instead of starting over, since it keeps context within a session.
- Ask it to take an action inside a supported app instead of only answering a question.
- Ask a general question that needs current information from the web.
Apple has also said some server-backed features will have daily limits, so heavy use may hit a cap at times.
Siri AI Not Showing Up? Fixes to Try
If you meet the requirements and still cannot see the option, work through this checklist.
- Check the device: confirm you have an iPhone 15 Pro or newer, or a supported iPad or Mac.
- Check the language and region: switch your device and Siri language to English and confirm you are not in the EU or China.
- Turn on Apple Intelligence: the feature will not appear until it is enabled and its models have finished downloading.
- Free up storage: the model download can be large, so a nearly full phone can stall the process.
- Restart and recheck: restart the device, reopen Settings and look again for the Try Siri AI (Beta) option.
- Rejoin the waitlist: if you were in the beta, sign up again on the public release.
- Be patient: if everything is set up correctly, the most likely reason is simply that your turn has not come yet.
Is Siri AI Worth Waiting For?
If you already rely on your iPhone for email, messages, photos and reminders, Siri AI is the first version of Siri that can work across that personal data in a conversational way. That is its real strength. If your main need is general research, writing or coding help, a dedicated chatbot is still the better tool, and it is reasonable to use both. To understand how autonomous assistants differ from chat-style tools, see our beginner’s guide to AI agents.
