OpenAI has unveiled its new AI-powered browser named ChatGPT Atlas, now available for macOS users globally with Windows, iOS and Android versions planned. The browser features an integrated ChatGPT sidebar that remains active as users browse, a “cursor chat” functionality that allows users to highlight text and ask ChatGPT to edit or analyse content in-line, and a memory function to retain context across sessions. This marks a direct challenge to Google’s Chrome dominance and signals a push for AI-first internet navigation. “A rare once-a-decade opportunity to rethink what a browser can be about,” said OpenAI CEO Sam Altman.
