ChatGPT Chrome extension reads and controls your open tabs

The upgrade turns the Chrome extension from a side panel into something that can act on what a user already has open. Two distinct modes are described: Chat mode pulls data from several tabs at once, while Work mode goes further and controls tabs through Computer Use. That split matters because it separates reading across a user's pages from taking actions inside them. The body gives concrete examples of the reading side — comparing products across tabs by size, material, shipping time, and return rules, summarizing articles in plain language, and matching price pages from different sellers. On the action side, Computer Use can send messages, fill out forms, download files, or group tabs. The body also places the full chat history in the upgraded sidebar next to the page being viewed, so the conversation and the browsing context sit together. OpenAI's own framing of GPT-6 Astra as the best Computer Use model on the market right now suggests the company sees multi-step browser control as a strength it wants to highlight. Availability is broad: the updated extension works with all ChatGPT plans.
