Atlas is designed to make everyday web tasks easier with AI support, and it's now available worldwide for macOS. Versions for Windows, iOS, and Android are in the works, but OpenAI hasn't announced release dates yet.

Atlas runs on Chromium, the open-source foundation behind Chrome and Edge. It brings standard features like tabs, bookmarks, extensions, and incognito mode, and layers OpenAI's language models support onto every website you visit.

ChatGPT can be launched from a new tab or a sidebar and automatically recognizes the context of the page you're viewing to deliver tailored responses. In text fields—such as forms or emails—ChatGPT offers inline editing and writing suggestions.

You can control Atlas using natural language commands like "Clear my tabs" or "Show me yesterday's shoes." These commands run right in the browser, with ChatGPT responding in context to the page you're on.

Atlas can optionally save your browsing history to help automate tasks or retrieve previous content. This memory feature ties in with ChatGPT's reminders and can be viewed, edited, or deleted at any time. It's turned off by default in incognito mode. OpenAI says your data won't be used to train AI models unless you actively opt in.
