⚖️ LexRAG — The Legal Intelligence Terminal
Enterprise-Grade Hybrid RAG for UAE & Indian Law, Taxation & Compliance
---
## What is LexRAG?
**LexRAG** is a professional-grade, high-performance Retrieval-Augmented Generation (RAG) platform purpose-built for **UAE and Indian laws, taxation, accounting standards, and corporate compliance**. It combines hybrid dense-sparse retrieval, neural reranking, auto-jurisdiction detection, and multi-provider LLM streaming into a zero-latency terminal interface.
