ChatGPT Atlas now makes browsing smoother with Arc-like vertical tabs. Users can switch from the traditional top tab layout to a left-hand sidebar, improving navigation and multitasking. This update is ideal for those who juggle multiple projects or research sessions, letting you see more tabs at once without cluttering your screen.
Activating the new vertical tabs is simple. Right-click inside the address bar, hover over “Tab Style,” and select “Vertical Tabs.” Once enabled, you can resize the sidebar, reorder tabs, and enjoy a cleaner browsing experience similar to Arc, while keeping the address bar at the top for quick searches.
While inspired by Arc, ChatGPT Atlas vertical tabs aren’t identical. They offer a lightweight sidebar for tab management but don’t yet include Arc’s advanced features. However, the update still boosts productivity by keeping tabs visible, easily accessible, and organized—perfect for researchers, students, or multitasking professionals.
Yes! Alongside vertical tabs, ChatGPT Atlas now lets you set Google as your default search engine. This combination makes the AI-powered browser even more versatile, letting you search efficiently while navigating multiple tabs seamlessly.
