How to use ChatGPT Atlas, a new OpenAI browser with enhanced personalization features (www.businessinsider.com)

OpenAI this week launched Atlas, a ChatGPT-powered browser for macOS that blends a chat-based interface with “agent” automation and new personalization features. Users sign in with a ChatGPT account, can import data from other browsers, grant keychain access, enable a “browser memories” toggle that remembers visited sites for contextualized search and quick recall, and use an “Ask ChatGPT” sidebar. In agent mode (limited to Plus, Pro and Business tiers) the AI can perform web tasks — the demo showed it parsing a recipe, calculating ingredients for eight people and auto-filling an Instacart cart — plus edit email drafts and search past browsing history in plain English. Atlas greets users via setup prompts and can be set as the default browser. The release signals a push to rethink browsing as conversational and agent-driven, creating a new front in AI competition with startups (Comet, Dia) and incumbents (Google, Microsoft). That rivalry has market implications — Alphabet shares moved on the news — and could shift web economics if users migrate and OpenAI captures ad or transactional revenue. Atlas also raises fresh privacy and safety trade-offs: OpenAI says agents operate only on open tabs and can’t execute code or access other local files, but storing browsing “memories” and granting keychain access expands sensitive data flows. For now Atlas is Mac-only and the demo agent stopped short of completing purchases, highlighting both promise and early constraints.
