Overview The goal of this capstone project is to develop a Generative AI–powered application that enables users to query enterprise documents using autonomous AI agents. The system uses Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), and Agentic AI frameworks to retrieve relevant information, reason over it, and generate accurate, context-aware responses. Project Description This project aims to build an AI agent–based knowledge and decision support system. The application allows users to upload documents in multiple formats (PDF, TXT, CSV, Excel) and ask natural language questions. The system retrieves relevant content using a vector database and generates grounded responses using an LLM. AI agents are used to plan the task, retrieve information,...
