Harvey AI
Harvey is an AI platform for legal and professional services — agents, a Vault for documents, Knowledge, Spaces, and Contract Intelligence — used by firms including A&O Shearman, Latham & Watkins, and Norton Rose Fulbright.
- Compliance stack is genuinely exceptional, including ISO 42001 for AI governance
- Built for legal work specifically rather than adapted to it
- Reasons over firm precedent that no general assistant can access
- Adoption by major firms functions as evidence of passed security reviews
- Institutional purchase with no self-serve route for small practices
- Output still requires lawyer verification — the professional duty does not move
- Faster review conflicts directly with hourly billing economics

- A customer list including major enterprises and magic-circle law firms
- Coverage from drafting through post-signature investigation in one platform
- Multi-model architecture is a defensible answer to single-model brittleness
- Surfacing model disagreement aligns with the asymmetric cost of contract errors
- Performance percentages are unaudited and state no baseline
- The models behind the architecture are not disclosed
- A six-module platform is an implementation project, not a subscription
