Gemini Nano is a built-in AI system in Google Chrome that runs writing help and page summaries locally on your Windows 11 PC, taking up about 4GB of storage space on your hard drive without sending your data to the cloud.
Turning off this feature deletes the AI files from your profile to free up disk space, though it stops smart browser tools from working until you download the files again.
Go to Chrome Settings, then System. Toggle the “On-device AI” option to On or Off. This setting controls whether AI models download to your computer, impacting storage and features.
How to Turn On-Device AI On or Off
- Open Google Chrome.
- Click the three dots button (
...) in the top-right corner. This is the “Settings and more” menu. Then, click on Settings. - In the left-hand menu, click on System. If you don’t see a left menu, you might need to click the three lines button (
☰) in the top-left corner or make your Chrome window wider. - You will see an option for On-device AI. You can choose to turn it On (which is the default) or Off.
- You can now close the Settings tab if you wish.



Turning on-device AI in Google Chrome on or off takes just a few clicks through the browser settings menu. You can manage this feature to control how your computer handles built-in artificial intelligence tools. Open Chrome settings, go to the system section, and use the toggle switch next to the on-device AI option to enable or disable it whenever you want.
Summary
Google Chrome controls whether AI models download to your Windows computer, directly impacting storage space and browser features.
