01 / Project Overview

LexisSearch RAG is a semantic search platform indexing legal precedents and firm case archives, enabling lawyers to search archives and find answers linked to citations.

02 / Business Challenge

Attorneys spent hours hunting through nested network folders and archive drawers to locate relevant case citations and historical arguments.

03 / Objectives

Establish an air-gapped legal RAG system that searches internal firm case files and drafts verified citations, saving attorneys 45 hours of case preparation time monthly.

04 / Our AI Solution

We deployed a private retrieval-augmented generation assistant using secure document vector models with strict context controls and citation page extraction.

05 / Implementation Journey

Our engineers deployed a private legal retrieval pipeline inside the firm's private VPC. We utilized pgvector and LangChain to fetch and display citation-backed case segments with zero public model training exposure.

06 / Business Outcome

Reduced research and case analysis preparation times by 75% while keeping all sensitive legal files secured within a private VPC network.
