Are there any RAG-based bots or systems for the humanities available to try online?

I’m currently exploring how Retrieval-Augmented Generation (RAG) systems could be applied in the humanities, especially in fields like philosophy, history, or literary studies. I was wondering if there are any publicly available RAG-based bots, tools, or prototypes online that are tailored (even loosely) to the humanities. I know that there are some „history AI Chatbots“ but are there web applications with which you maybe go through historical newspaper articles or the speeches of historical figures?
