Open Settings on your iPhone and tap Siri.

Turn Siri Off
Scroll to the bottom. Tap Turn Off Siri, then tap Turn Off Siri again to confirm.
THREE
Choose Siri Classic
Tap Turn On Siri, then choose Use Siri Classic. Some Apple pages shorten that button label to Siri Classic; choose the Classic option shown on your screen.

Changing Siri Settings? Make Sure Your Important Data Is Backed Up Too.
Siri and Apple Intelligence settings can be changed again later. Your photos, videos and important files are much harder to replace. If you are already reviewing your iPhone settings, this is a good time to review your backup plan too.

Big iOS 27 Change
Apple Intelligence Off Switch Missing? Here Is What Changed
If you are searching for a single master Apple Intelligence switch and cannot find it, you are not looking in the wrong place. Apple's current iOS 27 guide documents individual controls for specific Apple Intelligence features instead.
Do not follow outdated iOS 26 instructions blindly
Older guides may tell you to use one Apple Intelligence master toggle. For iOS 27, Apple's current support documentation instead tells you how to turn off Siri AI, summaries, priority notifications, smart replies, voicemail suggestions, Call Context, and other features separately.
| What you want off | iOS 27 path | What it changes |
|---|---|---|
| Siri AI | Settings → Siri → Turn Off Siri | Turns Siri off; turn it back on and choose Siri Classic if you still want Siri. |
| Messages summaries | Settings → Apps → Messages → Summarize Messages | Stops AI summaries from replacing conversation previews. |
| Mail summary previews | Settings → Apps → Mail → Summarize Message Previews | Turns off AI-generated Mail preview summaries. |
| Notification summaries | Settings → Notifications → Summarize Notifications | Stops stacked/long notifications from being summarized. |
| Priority notifications | Settings → Notifications → Prioritize Notifications | Stops Apple Intelligence from prioritizing selected notifications. |
| ChatGPT extension | Settings → Siri → Extensions → ChatGPT | Turns off ChatGPT access while keeping Siri AI available. |
| Siri AI capabilities via Screen Time | Settings → Screen Time → Content & Privacy Restrictions → Siri | Lets you allow Siri Classic, block Siri, or restrict specific Siri AI capabilities. |
Apple's available controls can vary by device, Siri version, language, and region.
Keep Siri, Remove ChatGPT
How to Turn Off ChatGPT in Siri on iOS 27
AI
If You Use Siri AI
Go to Settings → Siri → Extensions → ChatGPT, then turn off Use Extension.
S
If You Use Siri Classic
Go to Settings → Siri → ChatGPT, then turn off Use ChatGPT. Apple also provides a Setup Prompts control outside Siri AI.
This is different from turning Siri off. You can keep Siri and remove only its ChatGPT connection.
Troubleshooting
Siri AI Not Showing After Updating to iOS 27?
Check these before assuming the update failed.
1. Check Your iPhone Model
Siri AI requires an Apple Intelligence-capable iPhone. Apple currently lists iPhone 15 Pro and iPhone 15 Pro Max, iPhone 16 models or later, and supported newer models.
2. Match Device & Siri Language
As of September 26, 2026, Apple says Siri AI is currently available in English, and your device language and Siri language need to match a supported language. A mismatch can prevent the option from appearing.
3. Check Region Availability
Siri AI availability varies by region. Apple says it is not initially available on iOS in the European Union, and other regional restrictions can apply.
4. Look for “Try Siri AI (Beta)”
On a supported device, open Settings → Siri. Apple says the Siri AI setup option appears there when your device and account meet the requirements.
Quick compatibility answer
iPhone 15 vs. iPhone 15 Pro matters. Apple specifically lists the iPhone 15 Pro and iPhone 15 Pro Max as supported. A standard iPhone 15 does not become Siri AI-capable simply because it can run iOS 27.

If You Want Siri Completely Gone
How to Turn Off Siri Completely in iOS 27

Stop side-button activationIn Siri settings, turn off Press Side Button for Siri when available for your setup.
Reduce accidental wake-upsApple notes that placing iPhone face down prevents it from responding to “Siri” or “Hey Siri” in supported configurations.
Privacy & Conversation History
How to Delete or Auto-Delete Siri AI Conversations

30
Automatically Delete Old Conversations
Go to Settings → Siri → Keep Conversations, then choose an available retention period such as 30 Days or 1 Year. Apple warns older conversations are permanently deleted when the retention setting applies.
