Google makes current-tab sharing the default for Gemini in Chrome

Google says Gemini in Chrome uses the content of the user’s current browser tab by default after the feature is enabled, so the assistant can answer questions about the page already open in Chrome.

The help page also says users can share up to ten open tabs with Gemini, stop sharing a tab from the chat controls, or turn off default current-tab sharing in Chrome’s Gemini settings. For media sites, Google says a separate media-understanding setting is on by default and lets Gemini answer questions about audio or video the user has played.

The practical point is not that Chrome is secretly scraping every tab. Google frames Gemini in Chrome as an opt-in browser assistant, and the tab context is what makes summaries and page-specific answers work. But the default matters: once the feature is enabled, users who open Gemini should assume the current page may be part of the prompt context unless they change the setting.

For people using Chrome with work documents, dashboards or private accounts open, the safest habit is to check the Gemini in Chrome settings and disable automatic current-tab sharing if they want page access to be a deliberate per-chat action.
