Harvey in AI-Powered Research Tool

Answer in brief

AI software for law firms and in-house legal teams, covering research, document analysis and agents. Pricing and citation methods are not publicly documented.

Best for

Law firms and in-house legal teams doing high-stakes legal research and document work.

Pricing

Harvey does not publish prices, and its site offers only a demo request. A third-party aggregator reports a median annual contract of $175,000 based on four buyer reports; treat this as an estimate, not vendor pricing.

What it covers

Harvey's Knowledge product covers legal, regulatory and tax research. Vault stores and analyzes a firm's own legal documents, and its Connector Library links other tools to Harvey through MCP.

Citations and verification

Harvey's public product page does not describe citation or source-link features. Its October 2024 post reports a vendor-run hallucination rate for its assistant.

API

Harvey hosts developer docs at https://developers.harvey.ai for embedding its AI into internal systems. The intro page says access depends on the customer's contract and does not describe an authentication method.
