GoGreen DOC-AI
Legal Document Intelligence with 3-Tier RAG
Upload legal documents and get AI-powered summaries, Q&A with citations, and contract risk scoring. Built on a 3-tier RAG architecture — Basic RAG, LangChain RAG (ChatAnthropic + QdrantVectorStore + 5-turn memory), and Graph RAG (entity extraction + BM25 + RRF) — for unmatched accuracy and context.
