Overview
- Atlas is available worldwide on macOS now, with Windows, iOS and Android releases planned next.
- The browser adds an Ask-ChatGPT sidebar and browsing memory so the model can assist in context without switching tabs.
- A preview Agent mode can open sites, fill forms and complete tasks, initially limited to Plus, Pro and Business subscribers.
- OpenAI says users control permissions, can delete history or use incognito, and browsing content will not be used to train its models.
- Coverage noted a roughly 2.6% drop in Alphabet shares around the announcement as Atlas targets Chrome’s dominant market position.
