##I still have the following things to do
- [x] Recognize state diagram on p73 at least.
- [x] can we implement a better way of reading text from the pdf (which is fully working using langchain py pdfdirectoryloader) that can make better assumptions on the diagram text
- [x] is there a better way of splitting text?
- [ ] may want to deploy on streamlit for the sake of time.
- [ ] **Chat history. Remember previous queries**
- [ ] Work on slide deck
