Harvey
AI legal assistant for research, contract analysis, due diligence, and drafting across practice areas.
What it does
Harvey is an AI legal platform built specifically for law firms and legal departments, providing AI-powered research, document drafting, contract analysis, and due diligence capabilities trained on legal data and fine-tuned for legal reasoning. Harvey integrates with major law firm document management systems and delivers outputs in the precise formats and styles that legal professionals expect. Its AI can draft and review contracts, analyze case law and regulatory filings, produce due diligence summaries, and assist with discovery document review - going beyond generic AI tools to deliver work product that meets the quality standards of top-tier legal practice. Harvey is backed by OpenAI and used by several of the world's largest law firms.
Why AI-NATIVE
Harvey is AI-native - it is built from the ground up as an AI platform for legal work product. There is no non-AI Harvey product; the entire value proposition is applying legal-domain AI to accelerate and improve legal work.
Best for
Mid-size law firms and corporate legal departments use Harvey to accelerate research, first-draft document preparation, and contract review - reducing the associate time required for routine legal tasks.
Large law firms and Fortune 500 legal departments use Harvey for high-volume document review, due diligence, and regulatory analysis - with AI handling the bulk of document processing while senior attorneys focus on judgment and strategy.
Limitations
Harvey produces work product that requires attorney review before use — it accelerates legal work but does not replace the professional judgment, ethics obligations, and liability that attorneys must maintain.
Harvey's AI is more deeply trained on certain practice areas and common law jurisdictions — coverage for civil law jurisdictions, highly specialized practice areas, or non-English legal systems may be less reliable.
Law firms handle privileged client information — verifying Harvey's data handling, confidentiality protections, and model training practices is essential and must meet bar rules on client data protection before deployment.
