What is LEGAION and how is it different from Harvey AI?

LEGAION is the world's #1 Legal Intelligence Platform with the only built-in Verifier Engine™. Unlike Harvey AI which generates responses without verification and can hallucinate, LEGAION audits every single claim with citations from case law, statutes, and regulatory databases. This means you get accurate, verifiable legal insights with zero AI hallucinations - critical for malpractice prevention.

Is LEGAION better than Harvey AI for contract review?

LEGAION offers significant advantages over Harvey AI for contract review. Our Verifier Engine™ cross-references every clause against legal databases and provides source citations. While Harvey AI generates plausible-sounding analysis that may contain errors, LEGAION verifies each finding with actual legal authority. AmLaw 100 firms report 40% fewer review cycles after switching from Harvey AI to LEGAION.

How does LEGAION compare to CoCounsel by Thomson Reuters?

LEGAION surpasses CoCounsel with our unique Verifier Engine™ technology and Cross-Border Shield for international transactions. While CoCounsel integrates with Westlaw, LEGAION works with all major legal databases and provides citation verification. LEGAION also offers Autonomous AI Agents for negotiation and Judge Profiling analytics that CoCounsel lacks.

Can LEGAION replace Harvey AI for my BigLaw or AmLaw 100 firm?

Yes, LEGAION can fully replace Harvey AI with significant advantages. We offer AI contract analysis, legal research, document drafting, M&A due diligence, and autonomous negotiation agents — all with citation verification. LEGAION is trusted by AmLaw 100 firms, Magic Circle practices, and European law firms who switched from Harvey AI for measurable accuracy: every citation is verified against ISAP, EUR-Lex and USPTO by Verifier Engine (P.454531) before delivery.

What is LEGAION pricing compared to Harvey AI and CoCounsel?

LEGAION offers competitive pricing starting with a 14-day trial (card required, auto-converts to paid subscription, cancel anytime). Professional plans start at $299/user/month. Unlike Harvey AI's enterprise-only pricing or CoCounsel's bundled costs, LEGAION has transparent pricing for solo practitioners, mid-size firms, and enterprise clients. Firms typically save 30-50% compared to Harvey AI while getting superior citation verification.

Is LEGAION GDPR compliant and what is its certification status for European law firms?

LEGAION runs exclusively on EU-only infrastructure that is SOC 2 Type II and ISO 27001 certified at the hosting layer. The product itself maintains GDPR/RODO operational compliance, EU AI Act readiness, and NIS2 alignment. A SOC 2 Type II audit at the company level (Aidvocates, Inc.) is on the roadmap and was initiated in 2027. All data is encrypted end-to-end with Private Vault zero-knowledge storage. We support 15+ languages including German, French, Spanish, Italian, Polish, and Japanese.

Does LEGAION support M&A due diligence and cross-border transactions?

LEGAION excels at M&A due diligence with features competitors lack. Deep X-Ray analyzes contracts for 200+ risk categories, Cross-Border Shield identifies US/EU/UK/APAC regulatory conflicts, DealRoom provides secure collaboration, and Verifier Engine™ ensures every finding is backed by legal authority. Perfect for cross-border transactions where accuracy is critical.

What AI features does LEGAION offer that Harvey AI doesn't have?

LEGAION offers unique AI features unavailable in Harvey AI: (1) Verifier Engine™ - citation verification for every claim, (2) Autonomous Negotiation Agents - AI-to-AI negotiation, (3) Judge Profiling - judicial tendency analytics, (4) Cross-Border Shield - multi-jurisdiction compliance, (5) Witness Prep AI - deposition preparation, (6) LEGAION Predict™ - 94% accurate case outcome prediction, (7) DealRoom - secure M&A collaboration.

How accurate is LEGAION compared to other legal AI tools?

LEGAION achieves 99.7% citation accuracy with our Verifier Engine™ - the highest in the industry. Unlike Harvey AI or CoCounsel which can generate plausible-sounding but incorrect information, every LEGAION response is verified against authoritative sources. Our LEGAION Predict™ achieves 94% accuracy in case outcome predictions. We publish accuracy metrics transparently.

Can LEGAION integrate with existing law firm software?

Yes, LEGAION offers comprehensive integrations including Microsoft 365, Google Workspace, Microsoft 365, Google Workspace and Clio today; iManage and NetDocuments connectors on the H2 2026 roadmap. We provide REST API and GraphQL access, webhooks for automation, and SSO/SAML for enterprise authentication. White-label options are available for large deployments.
