Harvey is a powerful legal AI platform
Harvey has evolved from a chat tool into a comprehensive platform. With Assistant, Vault, Knowledge, Workflow Agents, and a mobile app, Harvey offers a broad range of tools for legal research, contract analysis, and drafting. Over 100,000 lawyers across 1,300 organizations use Harvey worldwide, including the majority of the AmLaw 100, 500+ in-house teams, and an increasing number of European firms such as Gleiss Lutz, Hengeler Mueller, and Schoenherr. Following the $200 million round in March 2026, Harvey is valued at $11 billion.
Harvey's strength lies in its breadth: Workflow Agents structure recurring tasks, Vault enables bulk document analysis, Knowledge searches over 200+ legal sources. The MS365 integration brings Harvey directly into Outlook and Word. For firms looking to accelerate research and drafting, Harvey is a serious tool.
The decisive difference lies not in the technology but in the outcome. Harvey delivers drafts and research results that an attorney must still review, approve, and take responsibility for. UNOY delivers finished work products according to playbook, with approval workflow, audit trail, and optionally with outcome accountability through certified delivery partners. That is a fundamentally different approach.
Differentiation
Where UNOY goes further than Harvey.
Harvey is a strong tool. Six dimensions show where UNOY takes a fundamentally different approach.
Kategorie 01
Draft vs. finished work product
Draft vs. finished work product.
Harvey delivers research results and drafts, including with Workflow Agents. UNOY delivers finished, approved work products: redline, brief, claim submission. With playbook documentation and audit trail for every clause.
Kategorie 02
Rule-based, not just AI
Rule-based, not just AI.
Harvey relies on AI chat and LLM-generated responses. UNOY combines rule-based processing with AI: rules determine what happens, AI assists where needed. Only this approach produces precise results where it matters: deadlines, clauses, calculations.
Kategorie 03
No outcome accountability
No outcome accountability.
Harvey accepts no accountability for its outputs. UNOY offers outcome accountability in the Supervised model through certified delivery partners: law firms, tax advisors, or compliance specialists who review and take responsibility for the finished result.
Kategorie 04
No-code workflow designer for experts
No-code workflow designer for experts.
Harvey is built for attorneys as users, not as designers. UNOY's no-code workflow designer is specifically conceived so that domain experts can encode their knowledge directly into a rule system: validation logic, decision trees, clause catalogs. No programming required. The integrated Know-Why section documents every rule: why it exists, on what legal basis, who last modified it. Only UNOY provides this depth of governance.
Kategorie 05
Pricing: accessible for smaller organizations
Pricing: accessible for smaller organizations.
Harvey targets large law firms and enterprise clients, with pricing to match. UNOY is designed so that smaller firms, legal departments, and sole practitioners can start profitably. From 50 matters per month, UNOY becomes economically viable, without an enterprise contract.
Kategorie 06
Three delivery models
Three delivery models.
Harvey offers a platform. UNOY offers three paths: Self (you build), Partner (we build together), and Supervised (we deliver the finished result). No other provider accepts end-to-end accountability for the outcome.
The honest comparison in detail.
| Dimension | Harvey | UNOY |
|---|---|---|
| Outcome Accountability | No, accountability lies with the attorney | Yes, via certified delivery partners (Supervised) |
| Output Form | Drafts, research results, analyses | Finished, approved work products |
| Work Level | Research, drafting, Workflow Agents | Matter processing end-to-end with playbook and approval |
| Delivery Models | One model: platform usage | Three models: Self, Partner, Supervised |
| Playbook Structure | Workflow Agents (preconfigured or custom) | Versioned playbooks with clause ID and audit trail |
| Word Documents | AI-generated drafts in Word | Word XML level: CI-compliant, redlining per playbook, hallucination risk reduced through schema, sources, and validation |
| DACH Jurisdiction | Growing (Gleiss Lutz, Hengeler Mueller as clients) | Native, DACH jurisdiction, EU data residency |
| Data Residency | US primary, EU instance available | EU native, GDPR, ISO 27001, SOC 2 Type II, ISO/IEC 42001 |
| Workflow Design | Developers configure agents | No-code designer, domain experts encode their knowledge directly into rules |
| Rule Governance (Know Why) | None; LLM outputs without rule documentation | Every rule documented: legal basis, change history, rationale |
| Processing Logic | AI chat, LLM-generated responses | Rule-based plus AI, precise results for deadlines, clauses, calculations |
| Entry & Pricing | Enterprise pricing, large-firm focus | Economically viable from 50 matters/month, including smaller organizations |
