OpenAI Launches ChatGPT Atlas, an AI-Centric Browser Aiming to Challenge Chrome

A macOS-first release embeds a page-aware assistant with an optional task‑running agent directly in the browser.

Overview

  • Atlas is available now on macOS for Free, Plus, Pro and Go users, with Windows, iOS and Android versions promised but not dated.
  • A built-in ChatGPT sidebar scans the current page to provide contextual help, while paying subscribers can enable an agent that controls the cursor to book travel, fill forms or edit documents.
  • OpenAI is positioning Atlas on the strength of ChatGPT’s reported 800 million weekly users to accelerate adoption.
  • A pre-announcement video showing browser tabs briefly pushed Alphabet shares down nearly 5% before the stock recovered after the demo.
  • The launch intensifies competition with Microsoft’s Edge/Copilot and Perplexity’s Comet against a regulatory backdrop that recently allowed Google to retain Chrome in a U.S. antitrust case.
