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.

EDUCATION · VERIFIABLE AI · LAW FACULTIES

Legaion
Campus

Free access to Legaion tools and an education program on verifiable AI in law. For law students, trainees and faculty.

Launch: October 2026

01 / Genesis

Why Legaion Campus
exists.

The first wave of AI in law enters firms without an instruction manual. A trainee opens ChatGPT, generates an analysis, hands it to a partner. The partner cannot tell whether the cited rulings exist. The client pays for output that nobody verified against the source.

This is not a problem of the tool. It is a problem of a missing educational layer that should run in parallel with the technology.

Legaion Campus is our answer — a free program for law students, trainees and faculty that teaches working with generative AI in a jurisdiction where substantive precision is the only acceptable standard.

04 / Curriculum · 6 modules

What you will learn in the program.

AI fundamentals for lawyers

Distinguishing generative models, retrieval-augmented generation, embeddings. What an LLM truly can and cannot do, why it hallucinates.

Verification architecture

How the Verifier Engine works. Cross-referencing citations against ISAP, EUR-Lex, SAOS. Why generation without a verification layer is a malpractice risk.

Working with documents and contracts

Contract analysis with Sentinel, Deep X-Ray, Cognitive Brief. Detecting hidden clause changes, mapping risks, generating business summaries for the board.

AI in litigation

Counter, Witness Prep, Predict — opposing-brief analysis, examination simulation, behavioural prediction of judicial panels.

Compliance and jurisdictional frames

EU AI Act for lawyers, GDPR when working with AI, attorney-client privilege at API calls, EU data residency as a compliance requirement.

Ethics and professional responsibility

When using AI is malpractice. Case study Mata v. Avianca and follow-on cases 2024–2026. Bar ethics standards toward AI.

How we think about education
of AI in law.

Future lawyers learn AI on their own from YouTube and Reddit. They generate briefs in ChatGPT, compile due diligence in Claude, check citations in Perplexity. Most of them have never heard the term “cross-model error correlation”. Most believe two models that agree are proof of truth.

This is not a deficit of student intelligence. It is a deficit of institutions. Law faculties in the EU are only beginning to introduce AI into curricula. In most cases this means a one-off lecture by an external guest, once per semester, for volunteers. That is a reaction, not a program.

Legaion Campus is our hypothesis of what such a program should look like. Built on three premises.

First — verification is the foundation, not an add-on. The first module is not “how to use ChatGPT”, it is “how not to become the next lawyer in Mata v. Avianca”. A student leaves Campus with a reflex to demand a source for every citation, not a reflex to trust the output.

Second — jurisdiction matters. AI in Polish, German and US law are three different categories of problem. English-language AI courses for lawyers will not solve a Polish firm working with ISAP, SAOS and KRS. Campus is Polish-first with extension to remaining EU jurisdictions.

Third — education must be free at the point of entry. Every financial barrier for a law student is a barrier to the quality of the legal market ten years from now. Access to Campus tools and materials is free for every confirmed law student, regardless of university.

These are our stakes. If the program works, by 2031 we will have a generation of lawyers who do not ask “can AI be right”, but “show me the source”.
