Built on Chromium, the app centers browsing on a persistent ChatGPT with memory features plus a preview agent.

Overview

  • Atlas is available globally on macOS today, with Windows, iOS and Android versions announced as coming soon.
  • The browser integrates ChatGPT through a persistent sidebar, cursor‑triggered help and on‑page summaries to assist across sites.
  • Agent Mode is in preview for Plus, Pro and Business users and can perform multi‑step tasks such as booking travel or editing documents under user control.
  • Privacy and safety controls include optional browser memories, clearing that removes related memories, site‑level permissions, a sandbox that blocks code execution and file access, and confirmation on sensitive sites.
  • Built on the Chromium engine, Atlas supports one‑click import of Chrome bookmarks, passwords and history, and Alphabet shares fell after the launch with reports of intraday losses approaching 5%.
