abstract = {This paper presents a conversational AI system capable of retrieving and synthesizing information from PDFs and web URLs using a hybrid retrieval-augmented generation (RAG) framework. The system integrates FastAPI for backend processing and Streamlit for a lightweight, user-friendly interface. By combining BM25 for keyword search with FAISS-based semantic analysis, the platform offers high retrieval accuracy and contextual relevance. Features such as document summarization, persistent conversation history (via SQLite), and modular architecture make the system well-suited for academic, research, and professional use.},
