Clippy by FireCube is a Windows 10/11 application that brings back the nostalgic Clippit assistant from Microsoft Office. It uses OpenAI’s GPT-3.5 model to provide conversational AI assistance, which users can pin to their desktop for quick chat access. The application features a Fluent Design/WinUI 3 interface, providing an alternative way to interact with GPT-3.5 through the iconic Clippy character.
