Tool Information
Harvey platform architecture and enterprise legal AI engine
Harvey (accessible at harvey.ai, founded by Winston Weinberg and Gabriel Pereyra) is the leading artificial intelligence platform engineered specifically for legal professionals, Am Law 100 law firms, and enterprise corporate counsel. Backed by OpenAI’s Startup Fund and major venture firms, Harvey integrates specialized legal foundation models with firm-specific knowledge repositories.
Built with enterprise-grade data security and strict confidentiality protocols, Harvey combines proprietary fine-tuned domain models with primary legal authorities (including comprehensive integrations with LexisNexis). The platform assists attorneys with contract analysis, due diligence, regulatory compliance, litigation preparation, and document drafting while guaranteeing zero data retention for model training.
Core capabilities and legal practice tools
Harvey delivers capabilities tailored to complex corporate legal workflows:
- Contract analysis & redlining: Reviews multi-hundred-page commercial agreements, flags non-standard clauses, and suggests redlines.
- Primary source legal research: Synthesizes case law, statutory codes, and regulatory guidance with citations to verified legal authorities.
- M&A due diligence automation: Analyzes virtual data rooms (VDRs) containing thousands of corporate records to identify risk factors.
- Regulatory compliance diligence: Tracks evolving international regulatory frameworks and assesses organizational exposure.
- Firm Knowledge Vault: Integrates securely with internal document management systems (iManage, NetDocuments) to leverage firm work product.
- Enterprise security & compliance: SOC 2 Type II certified, encrypted in transit and at rest, with isolated single-tenant deployment options.
