Our Hands-On Experience with Harvey
Harvey represents the frontier of AI applied to legal practice. Built on a custom model trained on vast legal datasets — including case law, statutes, regulations, and legal scholarship — Harvey understands legal concepts, reasoning patterns, and citation formats at a level that general-purpose AI tools can't match. The platform assists with legal research by finding relevant cases and statutes, drafting legal arguments, analyzing contracts for risks, and even suggesting litigation strategy. Allen & Overy's firm-wide deployment of Harvey validated the tool for BigLaw, and other major firms have followed. The multi-jurisdictional capability handles research across different legal systems, valuable for international law firms. Harvey's most compelling advantage is that it generates legal analysis with proper citations and reasoning structure, rather than the generic summaries that ChatGPT or Claude produce when asked legal questions. However, like all AI legal tools, its output requires careful human review — hallucinated citations remain a risk.
Most plans include a free trial — no commitment to get started.
