OpenAI has released a Windows app for ChatGPT, initially available only to paid subscribers. However, users can access ChatGPT for free on Windows by using the nightly version of Windows Terminal, a free Microsoft application. To download it, users must visit the GitHub page and select the appropriate version: the App Installer version for Windows 11 or the Portable ZIP version for Windows 10 and later. After installation, users need to enable the “Terminal Chat” feature and add an API key from OpenAI, GitHub, or Azure to interact with ChatGPT through Windows Terminal Canary.
