Harvey AI

Harvey AI is an enterprise AI platform built specifically for the legal industry. It assists lawyers with legal research, document drafting, contract review, due diligence, and litigation preparation using custom AI models trained on legal data. Harvey is used by some of the world's largest law firms (including Allen & Overy and other Am Law 100 firms) and legal departments.

The platform's legal-specific training means it understands legal concepts, terminology, and reasoning in ways that general-purpose AI tools cannot. Its LexisNexis partnership provides access to authoritative primary law content, and enterprise-grade security meets the strict compliance requirements of attorney-client privilege. The trade-off is that Harvey is exclusively enterprise — there's no self-serve option, free trial, or individual plan.
