ChatPPT is a powerful application built on the Model Context Protocol (MCP) designed to transform how users interact with their document collections, especially presentation files. It functions as a multi-document Retrieval-Augmented Generation (RAG) engine, allowing users to index and intelligently query multiple PPT documents based on visual models. By integrating with MCP, it enables sophisticated tool calls for deep analysis and smart Q&A, making it an invaluable tool for extracting insights from large volumes of unstructured data.
