OpenAI just pushed a major update to ChatGPT Atlas that brings Arc browser-style vertical tabs to its AI-powered browsing experience. The update also lets users set Google as their default search engine, signaling a more traditional approach to web search alongside ChatGPT's AI-generated summaries. It's the kind of incremental improvement that shows how AI companies are learning from established browser design patterns while building their own search experiences.
OpenAI just shipped what might be the most user-friendly update to ChatGPT Atlas yet. The AI-powered browser now sports vertical tabs in a left sidebar that looks strikingly similar to the beloved Arc browser - and honestly, it's about time someone borrowed from Arc's playbook.
The implementation feels familiar to anyone who's used Arc. You can resize the sidebar, drag tabs around to reorder them, and access everything through a clean left-hand interface instead of the traditional top bar. To enable it, you simply right-click in the address bar, hover over "Tab Style," and select "Vertical Tabs." It's not quite as polished as Arc's version - the address bar still lives at the top - but it's a solid start.
What's more interesting is the philosophical shift happening here. OpenAI also added the ability to set Google as your default search engine, which feels like an admission that sometimes people just want to Google things the old-fashioned way. As The Verge previously noted, using Atlas can sometimes "feel like Googling with extra steps."
The broader update package shows OpenAI is serious about making Atlas a daily driver. New users can now import extensions from their existing browsers during setup, though existing users will have to wait for this feature. There's also support for iCloud keychain passkeys, which should make the Mac-first browser feel more native to Apple's ecosystem.
Power users get some nice touches too. You can now select multiple tabs at once using Shift+click, and there's a new Control+Tab setting to cycle through recently used tabs instead of just going left to right. The downloads interface got a refresh as well, though OpenAI hasn't detailed what specifically changed there.
Atlas launched on macOS just last month, but it's already feeling the competitive pressure. Perplexity's Comet browser is making waves, and Google keeps enhancing Chrome with Gemini AI features. The AI browsing space is heating up fast, with each company trying to nail the balance between AI assistance and traditional web browsing.
