Harvey Legal AI

What is Harvey Legal AI?

Harvey (or Harvey AI) is a cutting-edge generative artificial intelligence platform built exclusively for the legal market. Founded in 2022 by Winston Weinberg (former litigation lawyer) and Gabe Pereyra (former AI researcher at DeepMind and Meta), the company received investment from the OpenAI Startup Fund. Harvey helps large law firms and global corporations conduct complex legal research, draft legal documents, and analyze large volumes of contracts with enterprise-grade precision and security.

How it works

Harvey uses OpenAI language models (such as GPT-4) customized and fine-tuned with enormous volumes of actual legal data, including case law, treatises, national and international legislation, and standard contract templates. The system operates privately and securely in the cloud. Lawyers can ask questions in natural language (e.g., "Identify abusive termination clauses in this 200-page merger and acquisition agreement") and the AI analyzes the text, drafts alternatives, and points to applicable legal sources.

Key features

• Intelligent Legal Research: Analysis of precedents and complex legal concepts crossing treatises and case law in minutes.
• Contract Analysis and Review: Deep scan of contracts to find regulatory gaps, tax risks, or inconsistent terms.
• Assisted Drafting of Pleadings and Opinions: Generation of custom initial legal drafts based on the premises provided by the lawyer.
• Automated Due Diligence: Rapid processing of thousands of corporate files during mergers, acquisitions, or internal audits.
• World-Class Data Security: Advanced end-to-end encryption and exclusion of data from public AI training pipelines to ensure attorney-client privilege.

Available integrations

Because it is a highly sensitive security and enterprise technology, Harvey is integrated with the document management systems (DMS) used by large law firms, in addition to connecting with private cloud repositories in isolated internal networks.

Who it is for

• Large international law firms managing complex cases and mergers and acquisitions (M&A) transactions.
• Legal departments of multinational corporations needing to audit internal contracts and ensure ongoing regulatory compliance.
• Consulting and auditing firms (such as PwC, which has an official strategic partnership with Harvey).

Real use cases

1. Accelerated Mergers and Acquisitions (M&A): A team of lawyers uses Harvey to analyze 5,000 vendor contracts of a company being purchased, mapping change of control terms in less than 24 hours.
2. Legal Opinion on Regulation: A tax lawyer interrogates the AI about recent high court decisions regarding taxes on digital services, obtaining a precise summary of applicable jurisprudence to support their final opinion.
