About Harvey
Harvey is a specialized AI platform for the professional services sector, primarily legal and tax. It was incubated by the OpenAI Startup Fund to apply large language models to complex legal workflows, helping elite firms process vast amounts of data with higher efficiency.
Official profiles
What it actually does
The platform analyzes legal documents to identify risks, summarizes case law, and drafts initial versions of legal memos or contracts. It allows users to query their own firm's data alongside public legal databases to find precedents and regulatory answers.
What makes it different
Harvey benefits from a deep partnership with OpenAI, giving it early access to model updates and the ability to fine-tune systems on proprietary legal datasets. Unlike generic chatbots, it is architected to sit within a firm's secure environment, ensuring client data is never used to train public models.

Pros & Cons
Strengths
-
Significant time savings on 'first-pass' review
Associates can skip the manual slog of initial document sorting and risk identification, focusing instead on high-level strategy.
-
Deep OpenAI partnership
Access to state-of-the-art LLM capabilities often before they are integrated into broader market tools.
-
High-fidelity source linking
Reduces the 'black box' problem by forcing the AI to show exactly where in the contract it found a specific clause.
Weaknesses
-
Opaque pricing and high entry barrier
The lack of public pricing and focus on enterprise contracts makes it impossible for smaller players to even test the tool.
Affects: Small to mid-sized law firms
-
Hallucination risk requires expert oversight
While fine-tuned, the tool can still generate incorrect legal citations or logic, necessitating a 'human-in-the-loop' for every output.
Affects: Junior associates who might over-rely on the tool
-
Implementation complexity
Integrating the tool with legacy document management systems can require significant IT resources and time.
Affects: IT and Operations departments

Frequently Asked Questions
How much does Harvey AI cost?
Harvey does not publish its pricing. It is sold as an enterprise solution, typically involving annual contracts that can reach six or seven figures depending on the size of the firm and the volume of data processed. There is no 'pro' or 'individual' plan.
How does Harvey compare to CoCounsel (Casetext)?
CoCounsel is generally more accessible to small and mid-sized firms with more transparent pricing. Harvey is positioned as a more bespoke, enterprise-integrated solution for Big Law and global professional services firms like PwC.
Is there a free trial for Harvey?
No, Harvey does not offer a public free trial. Access is usually granted only after a sales demo and a formal pilot agreement, which is typically reserved for large organizations.
Does Harvey use my data to train its models?
No. Harvey's enterprise agreements specify that firm and client data are siloed. Your data is used to provide answers to your firm only and is not fed back into the general OpenAI models or shared with other Harvey customers.
What integrations does Harvey support?
Harvey integrates with major legal Document Management Systems (DMS) like iManage and NetDocuments, as well as common enterprise tools like Microsoft 365 and Slack for workflow management.
Can Harvey replace a lawyer?
No. Harvey is a 'co-pilot' or assistant. It is designed to handle the mechanical aspects of research and drafting, but all outputs require review by a qualified legal professional to ensure accuracy and ethical compliance.
