Chat2Data: An Interactive Data Analysis System with RAG, Vector Databases and LLMs

Summary: Chat2Data enables natural-language analysis of unstructured and structured data. Its three-layer design combines domain-aware RAG, vector databases to reduce LLM calls, and pipeline agents for decomposed multi-round reasoning—targeting hallucination, cost, and accuracy.
