Interesting looking project, but I just looked at the repo. UIUC is such a great school. I managed an AI team in the UIUC Research Park for two years and interactions with professors and hiring a lot of student interns was a good experience.
Very true. The code is interesting and educational since the overall design is simple. Also true that the PDF to vector database code reminded me of something I would have done a couple of years ago. (I almost always now combine good old fashioned BM25 search with using chunk matching with embedding vectors.)
