How to Turn Off Google AI on iPhone: Safari, Chrome, and Gmail (2026 Guide)

If you searched on your iPhone today, you have probably seen a Google AI Overview appear above the actual results. Maybe a Gemini suggestion in your Gmail. Maybe an AI Mode toggle in Chrome. None of these can be turned off with a single switch on iOS, but you can disable each one with the right combination of settings.

This guide covers every Google AI surface on iPhone and the exact path to turn it off, organized by app.

The Short Answer

There is no single iOS setting that turns off Google AI everywhere. AI features live inside each Google app or in your account settings on google.com. The fastest results come from doing three things: turn off Smart features in Gmail (see our complete Gmail AI guide), sign out of AI-related Search Labs experiments, and use a Safari content blocker that hides AI Overviews on the search results page.

Turn Off Google AI Overviews on iPhone Safari

Safari does not let extensions modify Google search the way desktop browsers do, but content blockers work. The cleanest path on iPhone is a content blocker that hides the AI Overview block on Google.

1. Open the App Store on your iPhone.
2. Search for a Safari content blocker that supports custom rules or has a built-in Google AI Overview filter.
3. Install and enable it under Settings, Safari, Extensions.
4. Open Safari, search Google for any term, and confirm the AI Overview is gone.

If you do not want a third-party app, the fallback is to switch your default search engine. Open Settings, then Safari, then Search Engine, and choose DuckDuckGo, Ecosia, or another non-Google option. The AI Overview only appears on Google.

Turn Off Google AI Mode on iPhone Chrome

Google has been rolling out an AI Mode tab in Chrome on iPhone, often appearing as a Gemini icon next to the address bar. To remove it:

1. Open Chrome on iPhone.
2. Tap the three-dot menu in the bottom right.
3. Tap Settings.
4. Tap Google services or Sync and Google services.
5. Find Search assistance or Gemini and turn it off.
6. Restart Chrome.

If the AI Mode entry point appears in the omnibox itself, the control is in Chrome flags, but iOS Chrome does not expose chrome:flags the same way desktop does. The above settings are the only user-facing toggle. If the icon persists, check that you are signed out of any Google account that has AI Mode opted in at the account level. Go to myactivity.google.com and review Search Labs settings.

Turn Off AI in the Gmail App on iPhone

The Gmail iOS app inherits AI features from your Google account. Smart features and personalization is the master toggle.

1. Open the Gmail app.
2. Tap the menu icon in the top left.
3. Scroll down and tap Settings.
4. Tap your account email.
5. Find Smart features and personalization in this account and uncheck it.
6. Find Smart features and personalization in other Google products and uncheck it.
7. Tap Done.

This turns off AI summaries, Smart Reply, Smart Compose, and most Gemini suggestions in the iPhone Gmail app.

For Help Me Write specifically, there is no per-device toggle. It is tied to your Google One AI Premium subscription or Workspace admin policy. If you do not subscribe and it still appears, sign out and back in with only the account you want.

Turn Off AI Summary in iPhone Mail

Apple Intelligence on iOS 18 also generates summaries above emails in the Mail app. This is separate from Gmail Gemini. To turn off Apple's email summaries:

1. Open Settings.
2. Tap Apple Intelligence and Siri.
3. Toggle off Apple Intelligence, or scroll to Mail and turn off Mail summaries specifically if you want to keep other Apple Intelligence features.

If you read Gmail through the iOS Mail app rather than the Gmail app, the summaries you see come from Apple Intelligence, not Google. Disable them in Apple's settings (see our full Apple Intelligence summary guide).

Turn Off Google AI on iPhone 13 and Older

iPhone 13, 12, and earlier do not support Apple Intelligence at all, so AI summaries in Mail are not a concern. Google AI features in Safari, Chrome, and Gmail still apply, and the steps above work the same way regardless of iPhone model. iPhone 14 and earlier follow the same path. Only iPhone 15 Pro and iPhone 16 line support Apple Intelligence.

Turn Off Gemini Across All Google Apps on iPhone

If you want to disable Gemini across every Google app at once, the control is in your Google account, not on the device.

1. On iPhone Safari or Chrome, go to myaccount.google.com.
2. Tap Data and privacy.
3. Scroll to History settings.
4. Tap Web and App Activity.
5. Turn off Include Chrome history and audio activity.
6. Tap My Activity.
7. Search for Gemini and delete past activity.
8. Go to Search Labs at labs.google.com and opt out of any AI features you previously enabled.

This stops Gemini from learning new context and from feeding past activity into AI suggestions.

Use a Different Browser on iPhone

If the AI features in Safari and Chrome are too persistent, switching browsers is a one-step solution. Brave, Firefox Focus, and DuckDuckGo Browser do not show Google AI Overviews because they default to a different search engine and apply tracking protection that incidentally hides many AI elements.

Key Takeaways

There is no master switch for Google AI on iPhone. The right approach is to turn off Smart features in Gmail, install a content blocker for Safari to hide AI Overviews, and disable AI Mode in Chrome settings. For deeper control, manage your Google account at myaccount.google.com and opt out of Search Labs experiments.

If the cleanup goes well on iPhone and you also want to clean up Google search on your laptop, our Search Cleaner extension does for Chrome, Edge, and Brave on desktop what content blockers do on Safari iOS, with finer control over individual page elements.
