I let ChatGPT Atlas do my Walmart shopping for me - here's how the AI browser agent did (www.zdnet.com)

OpenAI has released Atlas, a Mac-only web browser that integrates ChatGPT with a full browser and — for Plus and Pro users — an “Agent” mode that can take control of tabs, move the cursor, click through pages, and complete real-world tasks. In a hands-on test, a ZDNet writer asked Agent to shop at Walmart for same‑day delivery. After granting permissions (importing Chrome data, using Apple Keychain, setting Atlas as default) and refining prompts, Agent navigated Walmart, pulled past purchases from order history to select preferred brands, populated the cart, and reached the checkout screen; the whole run took roughly 10 minutes. Initial obstacles included a language-selection pop-up, missing login/location data that prevented inventory checks, and the need for iterative prompts to get brand choices right. Technically this demonstrates how autonomous browser agents can interact with live sites, read account history, fill forms and handle multi‑step workflows — a big step toward automating errands like shopping or gift hunting. But it also exposes key limitations: fragility against unexpected UI elements (pop-ups), reliance on stored credentials and permissions, sensitivity to prompt phrasing, and site-specific behavior that may require manual sign-in or guidance. As a version 1.0 feature, Agent mode is promising for productivity gains but raises practical and privacy considerations; continued updates will determine how robust and widely useful these autonomous web agents become.
