ChatGPT Atlas introduces vertical tabs similar to the Arc browser
Just launched on macOS, ChatGPT Atlas is already evolving. OpenAI has unveiled a new vertical tab interface that closely aligns its intelligent browser with the experience offered by Arc — one of the most ambitious next-generation browsers.
This update aims to streamline navigation and reduce visual clutter.

ChatGPT Atlas: Vertical Tabs Inspired by Arc with a Flexible Sidebar
The most visible new feature is the introduction of vertical tabs, now accessible from a sidebar on the left. No more stacking tabs at the top: simply right-click in the address bar → Tab Style → Vertical Tabs.
Similar to Arc:
- The sidebar is resizable,
- Tabs can be reordered,
- The overall organization becomes more visual and controllable.
The address bar remains at the top, indicating that Atlas’s interface hasn’t yet achieved the full modularity of The Browser Company’s browser — but the direction is clearly set.
Google Can Now Be Your Default Search Engine
A recurring request: ChatGPT Atlas now allows you to set Google as the primary search engine. This decision makes sense, as using Atlas often resembled an enhanced Google search powered by ChatGPT, with a variety of sources and a link to Google Search displayed in the upper right corner.
With this update, ChatGPT Atlas embraces its role as a hybrid browser — both an AI engine and a gateway to the classic web.
Navigation Improvements: Multitabs, Extensions, and Downloads
OpenAI takes the opportunity to roll out several ergonomic tweaks:
- Selection and movement of multiple tabs by holding Cmd or Shift,
- Automatic import of extensions from your current browser upon Atlas installation (function forthcoming for existing users),
- A new, clearer download management interface,
- Support for iCloud Keychain passkeys, enhancing connection security.
These additions bring Atlas closer to a complete browser without compromising its AI-centric identity.
ChatGPT Atlas: An AI Browser Finding Its Place
Launched last month, ChatGPT Atlas is part of a wave of AI-augmented browsers along with Perplexity Comet and the Gemini extension for Chrome.
Its functionality is dual:
- Enter a URL to navigate “as usual,”
- Or ask a question to receive a contextualized answer from ChatGPT, accompanied by verified sources.
With the introduction of vertical tabs and enhanced settings, OpenAI refines its tool and strives to offer a credible alternative to traditional browsers — without abandoning its conversational aspect.
