Brave Tests AI Tab Management in Nightly Build, Letting Users Reorganize Open Tabs by Chat
Brave has added AI-driven tab management to its Nightly testing channel, letting users ask the Leo assistant to sort, group, move, and close open browser tabs through a plain-text chat prompt.
The Brave Nightly team announced the feature June 17 via a post on X, outlining four core actions Leo can now execute: rearranging tabs within a window, sending tabs to different or new windows, creating and editing tab groups, and closing unwanted tabs.
How It Works
Before Leo acts on any tabs, it surfaces a permission prompt that tells the user it will send the URL and title of every open tab to Brave AI and that it will gain the ability to move tabs around for that session.
The permission applies only to that specific conversation — not future sessions — which limits the scope of data access.
Leo’s chat input also now displays an “Open tabs…” option inside the attachment menu, allowing users to feed their current tab context directly into the assistant without typing each tab title manually.
What Testing Shows
In practice, the feature performs as described. A prompt reading “group my Reddit tabs” caused Leo to identify four open Reddit tabs, consolidate them into a new tab group labeled “Reddit Tabs” and colored orange, and leave an unrelated YouTube tab outside the group untouched.
The interaction required no manual drag-and-drop and no browser extension.
Nightly Only for Now
The feature has not yet reached Brave’s stable or beta release channels. Nightly builds function as Brave’s earliest public testing environment, where experimental features land before broader rollout.
Still, the tab management tool arrives as Brave moves quickly across several fronts. The company pushed its Containers feature — which isolates browsing sessions by context, similar to Firefox Multi-Account Containers — to its desktop beta channel earlier this week, according to PiunikaWeb.
Before that, Brave shipped Brave Origin to the stable channel on desktop and Android. Origin strips Leo out of the browser entirely, offering a leaner build for users who want no AI integration.
The Leo tab management feature sits at the opposite end of that product range, leaning further into AI assistance rather than removing it.
Brave, founded in 2015 by Mozilla co-founder Brendan Eich, built its browser around privacy-by-default features including ad and tracker blocking. It introduced Leo, its built-in large language model assistant, as a differentiator from rivals that rely on third-party AI integrations.
The Nightly build is available for download from Brave’s official site for users who want to test the tab management feature before it reaches wider release.
