OpenAI has officially launched ChatGPT Atlas, a groundbreaking AI-powered web browser that integrates ChatGPT directly into the browsing experience, marking a significant challenge to Google Chrome’s market dominance. This innovative OpenAI browser was unveiled on October 21, 2025, representing what CEO Sam Altman calls “a rare, once-a-decade opportunity to rethink what a browser can be”.
What is OpenAI Atlas?
OpenAI Atlas is a next-generation web browser that seamlessly integrates artificial intelligence into every aspect of online navigation. Unlike traditional browsers that simply display web pages, the Atlas browser transforms how users interact with the internet by embedding ChatGPT’s powerful language model directly into the browsing interface.
The ChatGPT Atlas browser is built on the open-source Chromium engine, the same foundation that powers Google Chrome, but with revolutionary AI features that set it apart from conventional browsing experiences.
