Harvey

Harvey is a generative AI platform specifically engineered for the complex, high-stakes requirements of the legal sector. Built on a foundation of proprietary legal-tuned models and a strategic partnership with OpenAI, Harvey provides a secure, enterprise-grade environment for law firms and in-house legal departments. By 2026, the platform has matured from a simple assistant into a comprehensive 'Professional Operating System,' integrating deeply with Document Management Systems (DMS) like iManage and NetDocuments. Its technical architecture focuses on high-fidelity Retrieval-Augmented Generation (RAG), ensuring that outputs are grounded in both global case law and the firm's private, historical work product. Harvey differentiates itself through 'Vault' and 'Workstreams,' features that allow for persistent institutional memory and multi-step automated legal reasoning. The platform is designed to handle massive-scale due diligence, multi-jurisdictional regulatory analysis, and complex contract lifecycle management. Positioned as the top-tier solution for Big Law (Global 100), Harvey maintains a closed-ecosystem approach, prioritizing data sovereignty and zero-retention policies for model training, ensuring that client-privileged information remains isolated and secure.
