ChatGPT Atlas
ChatGPT Atlas, a macOS web browser with ChatGPT built in, adds page-aware chat, browser memories and an agent mode.
Chat sidebar sees the current page; optional browser memories remember details from visited sites; agent mode takes multi-step actions in the browser without access to local files, passwords or autofill. Windows, iOS and Android were announced as coming.
