Multi-agent document analysis and self-correcting improvement system built with LangGraph, Groq (LLaMA 3.3 70B), ChromaDB, FastAPI, and React. Upload any PDF (contract, CV, report, certificate) and the system runs a 6-agent async pipeline: text extraction, summarization, key info extraction, risk analysis, risk scoring, and report generation — with RAG-based Q&A over the document.
