📜 PDFSense : PDF Question Answering Assistant with Chat History
PDFSense is an LLM-powered Streamlit application that enables users to upload PDFs and ask questions based on the document's content. It uses a Retrieval-Augmented Generation (RAG) approach to provide accurate, context-aware answers by incorporating previous chat history of the current session.

- Upload and analyze PDF documents.
- Ask questions about the uploaded PDF in natural language.
- Retrieve answers using LangChain, FAISS indexing, and Hugging Face embeddings.
- Maintain conversation context for coherent responses.
📚 How It Works
- Upload PDF: Drag and drop your PDF file into the uploader.
- Ask Questions: Type a question about the PDF's content.
- Contextual Answers: PDFSense retrieves answers using FAISS and LLMs while maintaining chat history for context.
