Upload PDF and get specific response on PDF with RAG app using Langchain, Gemini api, sentence-transformer, streamlit

ChatPDF is a Retrieval-Augmented Generation (RAG) app built with Streamlit that enables users to upload multiple PDFs and ask questions in natural language. The system extracts text, splits it into chunks, creates embeddings, stores them in FAISS, and retrieves relevant context to generate accurate, document-grounded responses using a local LLM.
