Generative AI built for elite law firms.
Harvey is the most-discussed legal AI platform of the post-ChatGPT era. Founded in 2022 by Winston Weinberg (a former O'Melveny associate) and Gabriel Pereyra (a former DeepMind research scientist), Harvey was the first generative-AI legal product to be deployed firm-wide at a top-tier firm — Allen & Overy in early 2023. It is now used at most of the AmLaw 100, including PwC Legal, A&O Shearman, Reed Smith, and CMS. Harvey is built on top of OpenAI's frontier models with significant fine-tuning on legal corpora, custom retrieval over firm and matter data, and agent workflows for drafting, due diligence, and research. Pricing is enterprise-only and is reported in trade press to range from $80–$120 per user per month at scale, with significant minimums.
