Overview
- Atlas is available now on macOS, with Windows, iOS and Android versions planned; its Agent Mode is a paid preview for Plus, Pro and Business users and operates only inside tabs without local file access.
- Core features include a persistent ChatGPT sidebar, “cursor chat” for inline edits, and optional browser memories that users can view, manage or delete.
- In live demos, the agent parsed a recipe and prefilled an Instacart cart, with safeguards such as asking before key actions and restrictions on code execution and unsupervised financial interactions.
- OpenAI says browsing content is not used to train models by default and memory is user‑controlled, though reporters have noted defaults that appeared to allow data sharing for model improvement.
- Analysts say Atlas intensifies the browser-search contest as reports noted an Alphabet share decline after the launch, and technical reviews point to Chromium underpinnings with Chrome extension support.
