AI-powered document ingestion, clause extraction, risk scoring, and lawyer sign-off for legal teams.
LexReview is an end-to-end AI-driven contract review platform built to streamline legal teams' contract review workflows and eliminate the manual bottlenecks in NDA and routine contract processing. The system automates PDF/DOCX upload and text extraction, intelligent clause splitting, AI risk analysis against firm playbooks, and client-ready report exportcovering the full path from document ingestion to lawyer sign-off.
Built on a NestJS and Next.js stack with TypeORM and Supabase (PostgreSQL, Storage, and Auth) for data and document handling, and Claude for clause-level risk analysis, LexReview lets legal professionals concentrate on critical judgment decisions rather than preliminary document screeningwithout removing them from the sign-off loop.
