Best way to create chatbot with own knowledge base from word files

I am looking to make a non profit chatbot (hobby projtect) for the construction sub reddit. For the chat bot I want to host on a domain and teach/reference it with my own data of around 35,000 word files (some have image diagrams almost like book pages).

Anyone know what’s the best way to go about this and what tool would be most efficient. People have suggested that I store the information on vector database but I wasn’t sure if it’s suitable for something like this with so many files.
