OpenAI is testing a ChatGPT app for Windows — but it’s only available to paid users for now. You can download an early version of the app from the Microsoft Store.

Just like the Mac version of the app, ChatGPT on Windows lets you ask the AI-powered chatbot questions in a dedicated window that you can keep open alongside your apps. You can quickly access the app by using the Alt + Space shortcut.

It also lets you upload files and photos to ChatGPT and comes with access to a preview of OpenAI’s o1 model capable of “reasoning.” The app is still missing some capabilities, however, such as advanced voice mode.

Shortly after OpenAI launched its ChatGPT app on Mac in June, a developer spotted a security vulnerability that stored conversations in plain text. OpenAI has since fixed this issue and now encrypts locally stored data.

Even though only ChatGPT Plus, Enterprise, Team, and Edu subscribers can use the app on Windows, OpenAI says it plans on bringing it to everyone later this year.
