Lexis+ with Protégé vs CoCounsel (2026)

Lexis+ with Protégé

by LexisNexis

CoCounsel

by Thomson Reuters

Pros

• ✓Outputs grounded in LexisNexis content + Shepard's Citations means verifiable legal citations rather than potential AI hallucinations
• ✓300+ pre-built workflows + Custom Workflow Builder reduces setup time vs starting from scratch
• ✓Microsoft 365 + DMS integrations (iManage, SharePoint, OpenText, Google Drive) means AI works inside existing legal workflows

Limitations

• ⚠Custom pricing without published reference rates makes budgeting harder than tools with public pricing
• ⚠Most useful when bundled with existing LexisNexis subscriptions -- standalone value depends on content licenses
• ⚠Newer Custom Workflow Builder is still maturing -- out-of-the-box workflows are stronger than custom-built ones today

Pros

• ✓Grounded in Westlaw -- research outputs cite authoritative primary sources rather than open-web content
• ✓Deep Research agentic capability handles multi-step research workflows that previously required hours of attorney time
• ✓20,000+ active customers and Am Law 100 majority adoption signals enterprise-grade reliability

Limitations

• ⚠Pricing visibility limited unless you're already a Westlaw customer or willing to engage sales
• ⚠Bundling with Westlaw means some buyers pay for legal research infrastructure they may not need
• ⚠Workflow library is pre-built; custom workflows are still rolling out incrementally
