  GPT4 & LangChain Chatbot for large PDF docs

It seems to be a paid version of https://github.com/mayooear/gpt4-pdf-chatbot-langchain

It uses langchain and pinecone to create a semantic index over the PDF content and search it based on question asked to sends the relevant information to openAI GPT api using embeddings.

  OP Vault ChatGPT: Give ChatGPT long-term memory using the OP Stack (OpenAI + Pinecone Vector Database). Upload your own custom knowledge base files (PDF, txt, epub, etc) using a simple React frontend.

Is this based on https://github.com/pashpashpash/vault-ai ? The UI looks remarkably similar.

IMO folks are better off deploying their own version where they can adjust a few knobs (e.g. split chunk size) to get better results, given that PDF Q&A is such a commodity application.

Wrote a <50 lines version with LangChain to run on your terminal with any folder full of PDF documents - https://github.com/angad/dharamshala/blob/main/docs.py

return_source_documents is particularly helpful to get a sense of what is being sent in the prompt.

  LLM Chain for answering questions from documents with citations

I tried it [1] a lot, but I must say it confuses me most of the time and I need to read the original text to check if it makes sense. Lots of times it doesn't.
