Let agents use the Browser

The AI Browser preview lets your sessions open and read web pages in their own tabs, and adds bookmarks, history and a side chat for you.

The AI Browser lets your sessions use the Browser: open a page, read it, click, type and take a screenshot. The agent works in its own tabs, apart from yours, and it never sees your sign-ins.

This feature is a Preview: it is still in development, so it stays off until you turn it on.

What turns on#

With the switch on, the Browser gains:

  • Bookmarks. A star in the address bar bookmarks the page, and your bookmarks show in a bar under the toolbar.

  • History. The History button opens a window with History, Memories (pages you visited, searchable by your sessions), Passwords (logins you saved for your own tabs), Journeys (your browsing grouped by topic), Permissions and Skills (recorded workflows).

  • A side chat. Toggle side chat parks a session's chat next to the page.

  • AI tools. Visual edit and Design mode let you point at part of your own app's page and have your session change the code. Write in field has your session write into a text box on the page. Record workflow saves the steps you take as a skill.

  • More tab tools. Command palette (Command plus KCtrl plus K in the Browser) searches your tabs, bookmarks and history.

How the agent uses it#

When a session uses the Browser, it opens its own tabs, marked as the agent's, on a separate profile. It cannot use the sites you are signed in to, and it can never read the logins you saved under Passwords.

Pause agent in the toolbar stops every agent action at once, so you can take over. Resume agent hands control back.

Choose what the agent may do on a site#

Open History > Permissions to set a rule for a site: let the agent act, only read, not read at all, or block the site entirely.
