ChatGPT’s Chrome extension can now control your browser tabs — not just read them. As of today, the free extension lets ChatGPT fill forms, send messages, download files, and group open tabs by topic, all while in Work mode. It does not auto-submit anything: when handling a dentist registration, for example, it stops before hitting “submit” so you can review first. No paid plan required. Free users get full access. The feature works inside ChatGPT’s web app or desktop app. No side panel needed. Just type @Chrome in any prompt, or name a specific tab to pull its content as context. Chromium browsers beyond Chrome are supported: Edge, Brave, Opera, Vivaldi. Firefox and Safari remain excluded. The update rolled out globally on October 18, 2026, and is live in the Chrome Web Store now. OpenAI retired its standalone ChatGPT Atlas browser in August, but this isn’t a retreat, it’s a pivot deeper into the browser you already use. For anyone searching “ChatGPT app”, “ChatGPT download”, or “ChatGPT desktop”, the answer hasn’t changed: there’s still no official native desktop app for Windows or macOS. What’s new is that the web app. Plus the Chrome extension, now behaves more like one. Next up? OpenAI says broader cross-browser support is “in development”, but gives no timeline. No word yet on Linux desktop integration or Firefox compatibility.
