A Web browser from OpenAI that integrates the ChatGPT chatbot. Built on the Chromium platform, the macOS version debuted in October 2025 for free and paid ChatGPT users with Windows and mobile versions forthcoming. Atlas enables users to browse the Web and ask ChatGPT in the same application. It can summarize the content on Web pages, and paid subscribers can shop for merchandise, book appointments, do research and fill in forms.
Browser design is somewhat mainstream and does not offer extensive customizing that some browsers such as Vivaldi offer. However, when many tabs are open, Atlas offers a scrolling feature that shows the full descriptions, but tabs remain horizontal instead of the more readable vertical format. See
