Harvey
Harvey won legal-AI distribution — 100,000+ lawyers, majority of the AmLaw 100 — but a rival's own published benchmark has it scoring below raw Claude on answer quality; you're paying ~€1,050+/seat/month for the workflow and security wrapper, not the smartest model in the room.

Strengths
Distribution is the moat: 100,000+ lawyers, majority of the AmLaw 100, 500+ in-house teams across 60 countries. Vault's bulk cross-document analysis (100,000 docs/project) is a genuinely differentiated M&A-diligence tool, security posture is enterprise-credible (SOC 2 Type II, ISO 27001, first AI/LLM startup certified under the EU-US Data Privacy Framework, EU/Switzerland/Australia data residency), and Agent Builder lets non-engineers ship custom workflows.
Honest dings
No independent, methodology-public accuracy benchmark from Harvey itself — a competitor's own published 19-model comparison scored it below raw Claude on every legal task category, and independent testers keep finding hallucinated citations on niche jurisdictions and recent case law. Pricing is fully opaque with a ~€250K+/year floor and steep add-ons (training, premium support, optional fine-tuning that contradicts the "we never fine-tune on your data" security claim).
