Backed by over $1 billion in funding from investors like OpenAI and Sequoia, Harvey acts as a virtual senior associate that never sleeps. It bridges the gap between raw data and actionable legal counsel, allowing firms to process thousands of pages of discovery or complex M&A documents in minutes.

Review
Harvey AI is an elite generative AI platform purpose-built for the legal and professional services sectors. Named after the iconic protagonist of Suits, Harvey was founded in 2022 by a former O’Melveny litigator and a Google DeepMind researcher to solve the “hallucination problem” in legal tech. By 2026, it has become the standard-bearer for domain-specific AI, utilized by over 1,000 customers in 60 countries, including “Big Law” giants like PwC, Allen & Overy, and Shardul Amarchand Mangaldas.
The platform is powered by proprietary large language models (LLMs) derived from GPT-4 but fine-tuned specifically on massive legal datasets, SEC filings, and global case law spanning 60 countries. Its core innovation is the Harvey Vault, a secure workspace where firms can upload up to 100,000 documents to be analyzed with 97% field extraction accuracy. While its high cost (up to $1,200/user/month) makes it an enterprise-only luxury, its ability to automate due diligence and draft complex litigation motions while providing citation-backed evidence makes it an indispensable asset for high-stakes legal strategy.

Professional Learning Curve
Getting Started with Harvey AI: Step-by-Step Guide
Step 1: Consultation and Security Audit
As an enterprise-only tool, you must contact Harvey’s sales team. They will perform a technical audit of your firm’s data infrastructure and security needs.
Step 2: Custom Model Training
Harvey is trained on your firm’s proprietary library, learning your specific “house style” and historical precedents to ensure tailored outputs.
Step 3: Setup Your "Vault"
Upload your project files (PDFs, Word docs, emails) into a Secure Vault. The AI will index and organize these into a searchable, analytical knowledge base.
Step 4: Deploy Agentic Workflows
Create “agentic bots” for common tasks, like a bot specifically for reviewing NDAs or another for drafting closing checklists.
Step 5: Verify and Refine
Use the side-by-side citation viewer to check every AI claim. Refine the output using natural language commands like “Make this more aggressive” or “Cite more recent precedents”.
