ChatGPT Atlas is a browser with an integrated sidebar that lets you summarize, compare, and analyze pages, and act on selected text for quick rewrites. Memory is optional and configurable. An agent mode (preview for Plus/Pro/Business users) can interact with websites to perform tasks under your control, with privacy settings such as per-site permissions, history clearing, incognito mode, and memory management.
