Our Verdict

Harvey AI is the leading enterprise legal AI platform, backed by Sequoia and OpenAI. It uses custom-trained GPT models to help law firms and corporate legal teams with legal research, contract drafting, document review, and due diligence. Harvey understands complex legal language and applies legal reasoning to surface subtle issues that keyword-based tools miss. The platform is used by AmLaw 100 firms and large corporate legal departments. Pricing is enterprise-only (not publicly disclosed) and requires a demo. While expensive, Harvey is the most capable legal AI tool for firms that handle complex, high-volume legal work.
