Harvey AI

Harvey AI

AI for legal work, built specifically for law firms and legal departments.

Finance & Legal AI Active #Legal#AIforLaw#Enterprise#DocumentAnalysis

In short

Legal-domain AI built for law firms rather than adapted from a general assistant. Handles legal research, document drafting, contract review, and due diligence in the contexts a lawyer actually works in, not the contexts a general AI was trained on.

What it is best at

  1. Legal research and issue spotting across case law and statutes
  2. First-pass contract review and redlining
  3. Due diligence document review at scale

Built for: Compliance/Audit Professionals · Enterprise Operations

Technical foundation

Base model
Built on frontier models (primarily OpenAI and Anthropic) with legal-domain fine-tuning and retrieval.
Context and file handling
Legal documents: contracts, filings, case documents, and statutory text.
Latency
Fast enough for interactive research. Document review at scale is batch.
Output quality and limits
Strongest for legal English and legal reasoning. Outputs still require lawyer review before any client-facing use.

Pricing and access tiers

Pricing, version numbers, context-window sizes, and compliance certifications change frequently. Where stated they are accurate as of the as_of date and should be confirmed with the vendor before any procurement or compliance decision. Where they could not be stated confidently they are omitted rather than guessed.

Legal-grade data terms. Client matter data is not used to train models. Verify the DPA for your jurisdiction.

The governance question this raises

The legal professional responsibility question is the same regardless of tool: a lawyer cannot delegate judgment to an AI, and outputs must be reviewed before they touch client work. What changes is which tasks can be accelerated. The professional liability point is that if Harvey produces a flawed contract clause and a lawyer submits it without review, the lawyer's error, not the vendor's. On the data side, privilege must be maintained for client matter inputs, which requires a confirmed data path under the firm's privilege policy, not just the vendor's standard terms.

No compliance certifications are listed here. Certification status is vendor-specific and time-specific, so it is stated only where verified rather than assumed. Check the vendor’s trust centre and confirm it covers the specific tier you are buying.
