What it is and who it's for
Harvey is a professional AI platform for lawyers: legal research, due diligence, drafting and document review with agentic workflows under enterprise security controls. Built for law firms and in-house teams (mostly large ones) that need AI tailored to legal work and compliance rather than a general-purpose chatbot. It stands out for enterprise maturity, legal-specific agents and wide adoption across the AmLaw 100.
Key features
- Legal research and analysis grounded in sources.
- Document drafting and review, due diligence across large document sets.
- Agentic workflows for specific legal processes.
- Works against the firm's own knowledge base and documents (Vault).
- Enterprise security and data controls.
- Integrations into a law firm's existing workflows.
Get started in 5 minutes
- It's an enterprise product — access goes through a demo or a chat with the team at harvey.ai.
- After onboarding, load your documents and reference material into the workspace (Vault).
- Assign research, drafting or review tasks and check the output against the citations.
When to pick it, when not to
- ✅ Pick it if you're a large firm or in-house team that needs comprehensive legal AI with security and agents.
- ✅ Pick it if high volumes of due diligence and drafting need to scale.
- ❌ Skip it → go with "Spellbook" if you want something more affordable that lives right inside Word for contract review and drafting.
- ❌ Skip it → go with "CoCounsel" if access to Thomson Reuters' Westlaw and Practical Law matters.
The honest price
Enterprise subscription on request (custom pricing, aimed at firms); there's no public self-serve tier. Exact numbers are on the vendor's site and do change.
Gotchas
- High barrier to entry and high cost — overkill for a small practice.
- AI doesn't replace a lawyer: every answer and draft still needs a professional's review.
- Rollout and integration take time and team training.
- Jurisdictional coverage depends on the underlying data — verify it for Russian law.
