Building a chatbot using Llamaindex, Langchain, and OpenAI API for document-based answers

Hello everyone,

I’m interested in building a chatbot that can answer questions based on a corpus of documents. I’ve heard that Llamaindex and Langchain are powerful tools for indexing and preprocessing text data. I’m wondering how it’s possible to integrate these tools together to create a chatbot that can retrieve relevant answers based on user questions.

I’m not sure about the specifics of how to do this, so I would appreciate any advice or resources that you might have. Are there any tutorials or guides that I can follow? I’m looking forward to your input.

note: part of the document is regarding how to code, and the user might ask what is the python code to do something.

Thanks for your help in advance.
