file2prompt is a simple desktop application built with C#, .NET, and Avalonia UI. Its purpose is to simplify the mass processing of text files using LLMs via the OpenAI API.
The application allows users to process multiple text files from a specified directory by combining their content with a customizable prompt template. Each file's content is sent individually to an LLM (via OpenAI API) in separate dialogue, and the responses are saved in a structured output folder, mirroring the input folder structure.
