About kotaemon
kotaemon is an open source, Apache 2.0 licensed Python project that provides a clean and customizable retrieval augmented generation (RAG) UI for chatting with documents. It sits in the AI and machine learning ecosystem, specifically under AI interaction and interfaces, and is built on Gradio so that the interface itself can be extended or modified. The README frames the project as serving two distinct audiences at once: end users who want to do question answering over their own files, and developers who want to build their own RAG pipeline on top of the framework.
