Prompt Refiner is a Windows desktop application designed to transform basic prompts into refined and comprehensive versions using the GitHub Copilot SDK. This tool is particularly useful for individuals involved in prompt engineering, as it effectively utilizes a large language model to enhance the clarity and precision of user input. The application is lightweight and offers both a graphical user interface (GUI) and a command-line interface (CLI), making it versatile for different user preferences and scenarios.

The application features real-time streaming capabilities, allowing users to see the refinement process in action. Additionally, it supports dynamic model selection, enabling users to choose the best model for their needs. The debug mode provides insights during the prompt refinement process, while copy-able error dialogs facilitate troubleshooting. Overall, Prompt Refiner serves as a powerful utility for anyone looking to improve their interaction with AI models.
