Overview
- Atlas is available globally on macOS today, with Windows, iOS and Android versions promised soon.
- Agent mode is in paid preview for ChatGPT Plus, Pro and Business customers and can handle multi-step web tasks such as bookings, form-filling and document edits.
- The browser defaults to a companion view that pairs webpages with a ChatGPT transcript, offers inline "cursor chat" editing and includes optional, controllable browser memories.
- OpenAI says browsing content is not used to train models by default, though one reviewer reported a default "model improvement" setting toggled on at install.
- Multiple outlets report Atlas is built on Chromium and supports Chrome extensions, and Alphabet shares fell after the announcement as investors assessed the competitive threat.
