Success Criteria

• Users can upload the following files from their fs
  • PDF, doc/x, md, epub, txt
  • Not a priority: image/ocr stuff
• Users can chat with the document (through a chat UI)

Later (Not in scope now but to keep in mind)

• Users can “create their own bot” by uploading a dataset, configuring system prompts and langchain map reduce stuff.
• Support other datatypes like sql, db, csv, json
• Use Llama-index or some other sort of framework to standardize working with this data
• VectorDB
• RAG integration
