Harvey is an AI platform built specifically for legal work, used primarily by large law firms and in-house legal departments. It combines document analysis, legal research, drafting assistance, and workflow automation in a single product, and is typically deployed as a firm-wide or department-wide tool rather than a per-lawyer self-serve subscription.
The platform is positioned around "domain-specific" AI for law: rather than a general-purpose chat assistant, Harvey builds workflows for tasks like contract analysis, due diligence review, and litigation research, with citations back to source documents. Harvey has disclosed partnerships with multiple AI model providers rather than relying on a single foundation model, and integrates with firms' existing document management systems.
Harvey markets itself heavily on data security: its published security page states it does not use client inputs, outputs, or uploaded documents to train underlying models, and it contractually requires model providers to maintain zero data retention.
Harvey sells primarily to large law firms (including several Am Law 100 firms) and large in-house legal departments; pricing is enterprise/quote-based and not publicly listed.
