GC AI’s In-House Legal AI for Companies, versus Harvey AI
Updated 1/15/25
Legal AI platforms differ a lot. You may have heard of Harvey. This page gives you everything you need to compare GC AI, the legal AI platform for in-house teams, with Harvey, an AI platform that initially launched with law firms and continues to serve them as its primary customer base.
You already know you need legal-specific AI. Legal AI is more precise with fewer hallucinations than general-purpose AI tools like ChatGPT. Legal AI also helps you meet your ethical responsibilities by keeping your queries secure, private, and privileged. And legal-specific AI can give you legal workflows, like helping review contracts or conduct legal research. Both GC AI and Harvey offer these advantages, but their similarities end there. Let's dive in.
GC AI is built for in-house and serves legal teams at 1,200+ companies. Legal teams and their needs are new for Harvey, and it shows.
GC AI is an enterprise-grade AI assistant trained specifically for in-house legal work. It connects your company’s contracts, policies, and data sources with the intelligence of modern LLMs, delivering precise, contextual answers that help legal teams accelerate business decisions. Unlike generic AI tools, GC AI understands contracts, compliance, and company context, so every answer aligns with how your business and legal team actually operate.
GC AI’s CEO and co-founder, Cecilia Ziniti, was a general counsel three times (Anki, Lambda School, and Replit), in-house counsel at Amazon and Cruise, and started her career in-house as a paralegal at Yahoo. Cecilia built the tool she wished she had, incorporating her taste about how to work with cross-functional teams, built right into GC AI’s system prompt, tone, and official prompts and workflows. GC AI provides business-focused answers, works intuitively from day one, and helps land your message with stakeholders. GC AI doesn’t produce lengthy memos, briefs with numbered paragraphs, or other law firm tasks as Harvey does.
In contrast, Harvey calls itself "Professional Class AI" for law firms and professional service providers (who bill by the hour) and, more recently, the Fortune 500. Harvey’s co-founder spent 10 months in Big Law, and the Harvey product reflects that heritage. Harvey spent a few years exclusively selling to law firms, then adapted for in-house teams. Today, Harvey reports 700+ law firms and enterprises as customers, compared with GC AI’s 1,200+ in-house legal teams.
At GC AI, we’re obsessed with in-house teams. That difference matters. As in-house counsel, you want AI that helps you move fast, communicates clearly with business teams, and helps drive your company’s growth while you protect for risk and get answers for the teams you support on legal issues and regulations. Your workflows aren't the same as BigLaw's, why should your AI be?
GC AI serves 1,200+ legal teams across companies of every size - from solo GCs to teams with hundreds of lawyers, from Bass Pro Shops to Liquid Death to Vercel. The majority of Harvey’s customers (and Harvey’s revenue) are very large law firms.
