The Problem

Associates were spending 4-6 hours per matter researching relevant case law, precedents, and contract clauses across a large internal archive.

The Solution

A RAG system with hybrid search (vector + BM25), cross-encoder re-ranking, and source attribution, returning top precedents with citations in minutes, not hours.

Business Impact

Associates reclaim research hours for strategy and drafting. Payback is usually measured in months once matter volume is stable.
