OpenAI on Tuesday unveiled ChatGPT Atlas, a long-anticipated artificial intelligence-powered web browser built around its popular chatbot, in a direct challenge to Google Chrome¡¯s dominance.

The launch marks OpenAI¡¯s latest move to capitalize on 800 million weekly active ChatGPT users, as it expands into more aspects of users¡¯ online lives by collecting data about consumers¡¯ browser behavior. It could accelerate a broader shift toward AI-driven search, as users increasingly turn to conversational tools that synthesize information instead of relying on traditional keyword-based results from Google ¡ª intensifying competition between OpenAI and Google. Shares of Alphabet, which owns the Chrome browser, were down 1.8% in afternoon trading.

ChatGPT Atlas is the latest entrant in a crowded field of AI browsers, which includes Perplexity¡¯s Comet, Brave Browser and Opera¡¯s Neon, as companies race to weave in tools that can summarize pages, fill out forms and draft code to attract users.
