Local llamaindex RAG to assist researchers quickly navigate research papers

RAG: Research-assistant

This project aims to help researchers find answers from a set of research papers with the help of a customized RAG pipeline and a powerfull LLM, all offline and free of cost.

For more details, please checkout the blog post about this project.

How it works

1. Download some research papers from Arxiv
2. Use Llamaindex to load, chunk, embed and store these documents to a Qdrant database
3. FastAPI endpoint that receives a query/question, searches through our documents and find the best matching chunks
4. Feed these relevant documents into an LLM as a context
5. Generate an easy to understand answer and return it as an API response alongside citing the sources
