What is Harvey AI?
Harvey AI is one of the most well-funded AI legal startups, having raised over $300 million from investors including OpenAI Fund and Google Ventures. It is built specifically for large law firms and professional services firms rather than for individual lawyers or small firms, and has signed enterprise agreements with major firms including PwC, A&O Shearman, and Linklaters.
Harvey's core legal capabilities include contract analysis and drafting, legal research with case law synthesis, litigation document drafting, M&A due diligence document review, and regulatory analysis. These are grounded in legal domain expertise rather than general AI capability — Harvey understands legal concepts, jurisdiction-specific requirements, and the conventions of legal document drafting in a way that general-purpose AI tools do not replicate without careful prompting.
The firm-specific memory capability allows Harvey to learn a firm's specific work product, templates, and approach over time, making suggestions more aligned with the firm's style than general AI tools. This institutional knowledge accumulation is a key long-term differentiator.
Harvey is positioned as an attorney productivity tool rather than a replacement for attorney judgment. All AI outputs require attorney review before use in professional work, and Harvey includes citations to source materials.
How Harvey AI works
Harvey AI runs as document analysis llm software built around text and document workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web.
