Atlas Is Dead, So ChatGPT Went Looking Through Your Open Chrome Tabs
Tag @Chrome and it reads whatever is open
OpenAI has upgraded its ChatGPT extension for Google Chrome so the assistant can reach into the tabs you already have open. In ChatGPT's web or desktop app, a user tags Chrome in the prompt, and the model can read the titles and contents of those tabs, pull information out of them, and act on it. The demo OpenAI posted shows someone asking ChatGPT to compare three tabs of sofas they are considering and then draft a comparison sheet. The sample prompts the company listed include filling a registration form from an event brief, adding an appointment to a work and personal calendar, and sorting vendors into a table with pricing, key features and source links. The capability is not always on: it fires only when Chrome is explicitly tagged, and that tag is the switch.
The sidebar moves in, and Work grows hands
The same update puts ChatGPT into a browser sidebar carrying, in OpenAI's phrasing, the full power of ChatGPT and your entire conversation history in Chat or Work, without leaving the page you are on. ChatGPT Work goes further and can control your Chrome tabs for sending messages, filling out forms and downloading files, as well as organising or grouping open tabs. OpenAI itself frames the feature as comparable to Google's Gemini-powered auto browse. Chrome is not the only target: the extension also covers Edge, Brave, Opera and Vivaldi. All five support tab mentions and browser control, while side chat reaches every one of them except Opera.
The context is that OpenAI's own browser is gone. ChatGPT Atlas launched on October 21, 2025, macOS only, was marked for deprecation on July 9, 2026, and stopped working on August 9, 2026 — 292 days from introduction to shutdown. The product lost on distribution, not on the idea. Rather than drop the browser agent, OpenAI relocated it into the browser people already run, which is why this upgrade reads as Atlas's replacement: the same agentic capability, now delivered through somebody else's permissions dialog.
One extension, your entire browsing session
The price is stated in the permissions. OpenAI's own documentation describes the extension as granting the ability to read and change all your data on all websites, read and change your browsing history on all your signed-in devices, and access the page debugger, plus bookmarks, downloads and tab groups. For ordinary users the payoff is skipping copy-paste: comparing prices, filling forms and sorting a trip without shuffling windows. But open tabs are exactly where personal and professional data concentrates — inboxes, dashboards, medical portals, contracts. One analysis argues the design shows some restraint, since nothing happens without the @Chrome tag and this is not passive surveillance; the flip side is that a single prompt is the only gate.
