Harvey is built on fine-tuned large language models specifically adapted for legal, regulatory, and tax domains, layered with retrieval-augmented generation (RAG) to ground answers in authoritative sources. The platform exposes multiple products — Assistant, Vault, Knowledge, Agents, Contract Intelligence, and Command Center — each targeting a specific part of the legal workflow. Harvey Agents execute multi-step legal workflows autonomously end-to-end, while the Command Center provides analytics and benchmarking for organizational AI governance. The platform is SOC 2-compliant and supports secure Shared Spaces for cross-organizational collaboration between law firms and clients.
