OpenAI Launches ChatGPT Atlas, an AI‑First Browser With Built‑In Agent Mode

The macOS release opens a new front against Chrome with a paid preview of agentic browsing.

Overview

  • Atlas is available now on macOS, with Windows, iOS and Android versions planned, and Agent Mode is in preview for Plus, Pro and Business subscribers.
  • Key features include a ChatGPT sidebar on any page, “cursor chat” for inline edits, and optional browser memories that users can view, delete or disable.
  • OpenAI says the agent operates only within browser tabs and cannot access local files, and a live demo showed it parsing a recipe and filling an Instacart cart.
  • Reporters flagged discrepancies in default data‑sharing settings and noted limited privacy controls at launch, despite OpenAI’s claim that browsing content is not used for model training by default.
  • Reverse engineering points to Chromium underpinnings and extension support, and coverage noted competitive pressure on Google with reports of an Alphabet share dip after the announcement.
