Harvey is an AI platform built specifically for legal work - contract drafting, legal research, due diligence, and litigation support. Built on top of Anthropic's Claude with legal-specific fine-tuning and retrieval, Harvey understands legal language, jurisdiction, and professional context in ways general AI assistants don't. Major law firms and legal departments use Harvey to accelerate high-volume tasks like contract review, document summarization during due diligence, and first-draft generation of standard legal documents. The system cites sources, flags uncertainty, and maintains the citation precision that legal work requires. At enterprise pricing targeting large firms, Harvey is positioned as infrastructure for law firms rather than a self-serve tool. The efficiency gains on partner-billed work represent significant economics for the firms that adopt it.
