Overview
- Atlas is available globally on macOS for Free, Plus, Pro and Go accounts, with Agent Mode in preview for Plus, Pro and Business and beta access for Enterprise and Edu if enabled by admins, and Windows, iOS and Android versions planned.
- A sidebar Ask ChatGPT offers page-aware help such as summaries, comparisons, data analysis and form completion without switching tabs.
- Browser memories are optional and user-controlled, allowing users to view, delete or block site-specific memories to manage privacy.
- Agent Mode can handle multi-step tasks like shopping or travel booking but cannot run code, download files, install extensions or access other apps or the file system, and it pauses before actions on sensitive sites.
- Built on Chromium, Atlas supports importing bookmarks, passwords and history from other browsers, and its launch intensified competitive pressure on Google as Alphabet shares fell roughly 2–3% after the reveal.
