Hello, I am trying to build an Q/A chatbot that can read pdfs along with the ability to read hand written comments. Has anyone tried to do this? Any tips to consider?

There are many great tutorials for this! The first question that you need to ask yourself is what programming language you want to work in. Here is an open source demo of a talk-with-your-pdf built with the framework I'm building (axflow): https://github.com/axflow/talktoyourpdf (it's in TypeScript)

Thanks, I am currently using python to do this. Do you know how to get the LLM to read handwritten notes?

You can OCR them w/tesseract (or a library that wraps around tesseract, such as OCRMyPDF)

Thanks!!
