To stop Gemini in Chrome from sharing your current tab by default, open Chrome Settings → AI innovations → Gemini in Chrome → Permissions and turn off Share current tab by default. The control stops default sharing of the current tab; it does not disable Gemini in Chrome.
What the current-tab setting controls
Google’s Chrome Help says the current tab is shared by default when Gemini in Chrome is opened. The setting controls that default. Google also says people can share other open tabs with Gemini.
How to turn off default tab sharing
- Open Settings in Chrome.
- Select AI innovations.
- Open Gemini in Chrome.
- Select Permissions.
- Turn off Share current tab by default.
The switch is specifically for sharing the current tab by default. Check that it is off in Permissions to confirm the setting is disabled.
What changes—and what does not
Turning off the switch stops the current tab from being shared by default when Gemini in Chrome opens. Gemini in Chrome itself remains available; this setting is not an on/off control for the assistant.
What Google says happens when tabs are shared
Google’s Gemini Help says that when tabs are shared, their URLs, page content, and media are sent to Google and may be reviewed for security. Google also says human reviewers may see conversations about shared tabs to improve Gemini.
If you use Gemini in Chrome to find pages you visited, Google says it collects relevant URLs from Chrome history as well. These statements concern interactions involving tabs shared with Gemini.
If the setting is not there
Google says Gemini in Chrome is rolling out gradually and may not yet be available in every country or territory.
