Harvey Review: Features, Pricing & Alternatives

What is Harvey?

Harvey is a generative AI platform built for legal and professional services work. Lawyers use it to research legal, regulatory and tax questions, draft and review documents, analyse thousands of files in secure Vaults and hand multi-step tasks to agents. It is sold to law firms, corporate legal departments and professional services firms rather than to individuals, and it runs in the browser, inside Microsoft Word and Outlook, and on mobile.

Harvey was founded in 2022 by Winston Weinberg and Gabe Pereyra and has grown quickly. In September 2026 it announced a $550 million funding round at a $15.5 billion valuation, and its website says more than 3,000 law firms and in-house teams in over 70 countries use it. In August 2026 it launched Harvey II, and in 2026 it also made several acquisitions, including the AI security company Guardrails AI.

What sets Harvey apart is depth inside large organisations. Harvey II gives agents the context of a matter, its documents and permissions, plus a memory of each user’s formatting and citation preferences, and it introduced Tenet, a model post-trained for legal reasoning. Spaces add shared workspaces with ethical walls. Its site lists SOC 2 Type II, ISO 27001, ISO 27701 and ISO 42001. Outputs still need review by a qualified lawyer.

Harvey vs alternatives

Harvey competes most directly with CoCounsel from Thomson Reuters and Lexis+ with Protégé from LexisNexis. Those two have a natural advantage in legal research because they sit on Westlaw and Lexis content, while Harvey focuses on a broad agent platform, secure vaults and collaboration. Research-heavy firms weigh content access against Harvey’s workflow depth.

For contract-focused work, Spellbook offers a lighter Word add-in that smaller firms can trial, and Luminance targets in-house contract negotiation and portfolio analysis. General assistants like Claude or ChatGPT cost far less but lack legal-specific workflows and governance. See all best AI legal and finance tools.
