ChatGPT Atlas reimagines the browser as an AI-powered super-assistant, merging ChatGPT’s conversational intelligence with seamless, context-aware web navigation. Instead of toggling between pages and chats, Atlas allows ChatGPT to understand the site you’re viewing and help directly within it—summarizing content, completing forms, or finding related information in real time. Built-in browser memory means your assistant can recall previous pages, projects, and goals, offering continuity across sessions. The optional agent mode lets ChatGPT autonomously perform tasks—like researching, scheduling, or analyzing—while visibly showing its actions to maintain transparency and user oversight. Privacy remains central: you can turn off visibility, clear browsing memories, or go incognito at any time. Designed with enterprise-grade safety, Atlas prevents access to local files or unapproved apps, minimizing risks from hidden or malicious web instructions. It also supports parental controls and customizable data-sharing options, giving users full command of how their information is used. Available today for Free, Plus, Pro, and Business users, ChatGPT Atlas marks the next evolution of intelligent, secure browsing.
