About This Tool

Harvey is an exclusive AI platform specifically fine-tuned for legal work. Backed by the OpenAI Startup Fund, it is not a general-purpose chatbot but a specialized legal assistant. It helps attorneys synthesize thousands of pages of case law, draft complex contract clauses, and research regulatory changes in seconds.

How to Use

  1. 1. Access is currently by invitation/waitlist for major firms (e.g., Allen & Overy).
  2. 2. Upload case files, contracts, or discovery documents securely.
  3. 3. Ask Harvey to “Summarize the liability clauses in these 50 leases.”
  4. 4. Request a first draft of a legal memo based on specific facts.
  5. 5. Review and verify citations (Harvey provides references).

Use Cases

Harvey is deployed in “Magic Circle” and “Big Law” firms to handle high-volume, low-complexity tasks. It allows associates to conduct due diligence on mergers 10x faster, analyze regulatory compliance across different jurisdictions, and draft initial client communications.

Partnerships

Harvey made headlines through a strategic alliance with Allen & Overy (now A&O Shearman) and PwC. These partnerships provided Harvey with access to massive proprietary legal datasets, allowing it to fine-tune its models far beyond what standard ChatGPT can achieve.

Security & Privacy

In the legal world, confidentiality is paramount. Harvey is built with enterprise-grade security, ensuring that client data is encrypted and isolated. Unlike public models, data processed within Harvey for one firm is not used to train the model for another firm.

Limitations

Currently, Harvey is highly exclusive. It is not a tool you can simply sign up for with a credit card; it requires an enterprise contract. It is designed to *assist* lawyers, not replace them—human review is strictly required for all outputs to avoid “hallucinations” in legal citations.

Generative Reasoning

Harvey excels at multi-step reasoning. You can ask it, “If we change clause X in this contract, how does it affect our liability under Regulation Y?” and it will provide a reasoned analysis connecting the contract language to external laws.
