I‘m using it in for an internal application and the results so far are amazing. Considering it was hacked together in a few hours.

It helps a lot with discovery. We have some large PDFs and also a large amount of smaller PDFs. Simply asking a question, getting an answer with the exact location in the pdf is really helpful.

From our experience simple RAG is often not that helpful as the questions itself are not represented in the vector space (except you use an FAQ dataset as input). Either a preprocessing by an LLM or specific context handling needs to be done.
