Overview
- Atlas is available now for macOS with Windows, iOS and Android versions promised, and its Agent mode is limited to Plus, Pro and Business subscribers during the preview.
- ChatGPT is embedded in a sidebar that can read the current page, summarize content, recall prior activity and accept natural‑language commands such as reopening items or tidying tabs.
- The Agent can carry out web tasks like opening sites, filling forms and assembling shopping carts, with user controls to pause or stop actions and optional access to logged‑in accounts.
- OpenAI says visited content is not used to train models by default and offers controls including a memory toggle, incognito mode and the ability to delete browsing history.
- Built on Chromium, Atlas supports Chrome extensions and imports from Chrome, and its launch was framed as a direct challenge to Google’s market‑leading Chrome as Alphabet shares fell about 2–3% after the announcement.
