Harvey AI

Harvey AI is a generative AI platform built specifically for legal work. Founded in 2022, it has become one of the most widely adopted AI tools in the legal profession, used by major law firms including A&O Shearman, Paul Weiss, and several global consulting and professional services firms.

The platform is purpose-built for legal tasks that traditionally require significant billable hours: reviewing and summarizing contracts, conducting legal research across case law and statutes, running due diligence on transactions, checking regulatory compliance, and drafting legal documents. Harvey is trained on legal corpora rather than general internet text, which produces outputs that fit legal conventions more accurately than general-purpose AI.

**What it does well**

Harvey excels at high-volume legal document work — the kind of work junior associates have historically handled in bulk. Lawyers using Harvey report reviewing contract bundles in a fraction of the normal time, with the AI flagging unusual clauses, summarizing key terms, and highlighting risk areas before any human review.

For legal research, Harvey can synthesize case law across jurisdictions quickly. This is particularly valuable for matters spanning multiple legal systems, where assembling a comprehensive picture used to require days of manual research. Its regulatory compliance feature helps legal teams analyze how new regulations apply to specific business situations without starting from scratch each time.

Document drafting with Harvey is not simple autocomplete. The system understands legal document structure, clause relationships, and common practice across different deal types — making its first drafts more usable than what most general AI produces for legal work.

**Limitations**

Harvey is an enterprise product. It is built for law firms, in-house legal departments at large companies, and professional services firms. Pricing is custom and enterprise-only, making it inaccessible for solo practitioners, small firms, or individuals with occasional legal needs.

Like all AI legal tools, Harvey requires professional oversight. It is designed to accelerate attorney work, not replace attorney judgment. Outputs should always be reviewed by a qualified legal professional before use in any matter.

**Who it is for**

Large law firms and enterprise legal teams looking to improve efficiency on high-volume document review, legal research, and compliance work. Harvey is most effective as a productivity layer for teams with structured legal workflows, not a starting point for people without legal training.
