How to DISABLE Chrome AI Features & Gemini (2026)

Key takeaways

• Chrome 146 enables 5+ AI features by default. Gemini sidebar, page content sharing, and AI Mode flags are all on unless you turn them off.
• Page content sharing is a separate toggle from the Gemini sidebar. Disabling Gemini alone does not stop tab text from being sent to Google.
• AI Overview has no Chrome setting. Change it in Google Search preferences or use a CWS extension like “Bye Bye Google AI.”

Chrome opened a browser window one day and the Gemini icon was just there. No permission prompt. No announcement in the UI. Just an AI assistant sitting in the toolbar with access to every page you load. If you didn’t ask for it, or if you care what gets sent to Google’s servers, these are the exact steps to remove it.

What Chrome’s AI Features Actually Do

Before touching settings, it helps to know what each feature sends where. Chrome 146 (March 2026) ships five AI-driven features, most enabled by default for qualifying accounts:

Auto Browse is the most invasive: it feeds a live session context to Gemini across your entire browsing window. As of March 2026 it requires a paid Google AI Pro or Ultra subscription and is only available in the US. If you are outside the US, it won’t appear. The other four features may still be active.

The CVE-2026-0628 vulnerability (disclosed and patched in early 2026) demonstrated that a malicious extension could hijack the Gemini panel’s elevated permissions to request camera, microphone, and file access on behalf of the AI session. The patch landed, but the architecture illustrates why giving a side panel AI access to your page content is a meaningful attack surface, not just a privacy preference.

Disable the Gemini Sidebar

The Gemini sidebar is the most visible AI addition to Chrome. It appears as a small icon in the toolbar (US, CA, IN, NZ only; English-US Chrome; 18+; gradual rollout). If you don’t see it, your account hasn’t been included yet.

1. Open chrome://settings in the address bar
2. Type Gemini in the search box, or navigate to You and Google → Gemini in Chrome
3. Toggle Gemini in Chrome to off
4. Confirm the dialog if prompted

The toolbar icon disappears immediately. Tab summarization, the “Help me write” inline prompt, and Auto Browse all stop working. They depend on the Gemini toggle.

If the Gemini toggle doesn’t appear in your settings, either your Chrome version is below 121, your account region doesn’t qualify, or the feature hasn’t rolled out to your profile yet. In that case there is nothing to disable. The feature isn’t active.

Disable Page Content Sharing

This step is separate and easy to miss. Turning off the Gemini sidebar doesn’t automatically revoke the page content sharing permission. Chrome stores these as independent settings.

1. Go to chrome://settings
2. Navigate to You and Google → AI features
3. Find Page content sharing (or Sharing content with AI features)
4. Toggle it off

With this off, no AI feature in Chrome, including any future ones Google adds, can read your active tab’s text. The toggle covers the entire AI features system, not just Gemini.

If you are signing into a shared or work machine, also check that the same toggle isn’t overridden by an enterprise policy. Go to chrome://policy and search for GenAI. Any entries there mean an administrator has set the value and your change will be overridden on restart.

Disable AI Overview in Google Search

AI Overview is where Chrome stops being able to help you. This is a Google Search product setting, not a Chrome setting. There is no chrome://settings entry that removes it.

Method 1: Google Search settings (most reliable)

1. Go to google.com and search for anything
2. Click Settings (bottom-right on desktop, or the gear icon)
3. Select Search settings
4. Find AI Overview and suggestions
5. Select Don’t show AI Overviews and suggestions
6. Scroll down and click Save

The setting persists across sessions when you’re signed into your Google account. On mobile, the path is Search → Settings → AI Overview.

Method 2: CWS extension

Two extensions specifically target AI Overview removal:

• Disable AI Mode & AI Overview — available on CWS, blocks the AI Overview element via CSS injection and URL parameter modification
• Bye Bye Google AI — similar approach, adds &udm=14 to search URLs which switches Google to the “Web” results view without AI Overviews

Both are lightweight content scripts with no server communication. The udm=14 parameter is the most reliable technical approach: it instructs Google to return traditional web results.

What you can’t remove: Even with the Search setting off, Google occasionally injects AI-generated content for certain query types in some regions. The extension approach is more consistent.

Disable AI Mode and Experimental AI Flags

Chrome’s AI Mode in Google Search (a more aggressive AI-first search layout currently in early rollout) can be targeted specifically through chrome://flags:

1. Open chrome://flags in the address bar
2. Search for AI. You’ll see a list of experimental features.
3. Key flags to disable:

4. Click Relaunch at the bottom of the page to apply changes

A note on #optimization-guide-on-device-model: when this is enabled, Chrome downloads a Gemini Nano model file (roughly 1.7GB) to your local storage in the background. If you’ve noticed unexplained disk writes or Chrome using unexpected storage, this flag is the likely cause. Disabling it and restarting Chrome stops the download and allows you to reclaim the space from chrome://settings/storage.

Not all flags appear in all Chrome versions or channels. Flags reset on some Chrome updates. Check after major version upgrades.

Disable Page Content Sharing for Specific AI Features

Beyond the main toggle, Chrome’s AI features settings page has granular sub-controls that are worth reviewing even if you keep some features on:

1. Go to chrome://settings/syncSetup → AI features (or directly at chrome://settings#privacy)
2. Review each item under the AI features section:

Disable any you don’t actively use. The cumulative data surface across all these features is larger than the Gemini sidebar alone.

Nuclear Option: Chrome Policies for Full AI Lockdown

For shared family machines, kiosk setups, or privacy-focused environments where the individual toggles might get re-enabled by other users or Chrome updates, policy-level controls are more durable.

Windows (Registry or GPO):

1. Download the Chrome ADMX templates from Google’s policy page
2. Add the templates to your Group Policy editor
3. Navigate to Computer Configuration → Administrative Templates → Google → Google Chrome → AI features
4. Set Generative AI settings to Disabled (2)

Or directly in the registry at HKLM\Software\Policies\Google\Chrome:

• GenAILocalFoundationalModelSettings = 1 (disable on-device model)
• CreateThemesSettings = 1 (disable AI theme creation)

macOS (plist):

Place a com.google.Chrome.plist file in /Library/Managed Preferences/ with:

<key>GenAILocalFoundationalModelSettings</key>
<integer>1</integer>

Chrome://policy verification:

After applying any policy, go to chrome://policy and confirm the values appear under “Machine Policies.” If they show as user-level only, the policy isn’t fully locked. Other user profiles on the machine can still override them.

Policy-level settings survive Chrome updates and profile resets, unlike flags.

What You Lose (and What You Don’t)

The one practical loss: Help me write in form fields is a feature some users rely on heavily. If you disable AI features globally but want that specific one, re-enable only the “Help me write” toggle in chrome://settings → AI features while keeping page content sharing and the Gemini sidebar off.

AI Overview in Search is the most disruptive to disable if you rely on Google for research. The results page layout changes noticeably. The traditional web results view (udm=14) shows cleaner organic results, which many users find more useful for navigating to sources directly.

A Different Approach to Focused Browsing

If the underlying frustration isn’t Gemini specifically but the general drift toward a browser that tries to do your thinking for you, with tabs cluttered with suggestions, side panels filling up, and constant ambient UI, that’s a different problem than a single AI toggle can fix.

SuperchargeNavigation takes the opposite approach to AI-driven browsing: named workspaces that separate your contexts (work, research, personal), an Alt+K command bar for navigating without touching the mouse, and Shift+Click to peek at a link without leaving your current tab. The side panel is used for workspace switching, not AI chat. Zero telemetry. 100% local. No account required.

If your goal is a browser that responds exactly to what you direct it to do, rather than one that anticipates and injects, workspace-based navigation is worth considering alongside the AI disabling steps above.

Most users only need to disable page content sharing (the biggest privacy gap) and leave the rest alone. For a full AI-free Chrome, work through sections 2–5 above. The whole process takes under 10 minutes.
