CoCounsel pros and cons
Integrates directly with Thomson Reuters' proprietary legal content, so research and drafting draw on authoritative case law rather than open-web sources
Deep Research workflows use agentic AI to break complex questions into research plans and return source-linked answers, reducing the risk of unverifiable output
Covers a genuinely broad range of legal tasks in one assistant — research, discovery-scale document review, contract analysis, and brief proofreading
Fits naturally into existing Westlaw and Practical Law workflows, letting firms already on those platforms add AI without switching systems
Premium pricing that is typically bundled with Westlaw makes the total cost high, and standalone value is weak for firms not already in the Thomson Reuters ecosystem
Case law access is not always included in lower tiers, so the effective price to get full functionality can climb well above the headline figure
Deep reliance on the Thomson Reuters stack creates meaningful vendor lock-in
Definely pros and cons
Works natively inside Microsoft Word
Reduces manual defined-term checking
Multiple tools across drafting and review
Low workflow disruption and learning curve
Pricing is not public
No standalone mobile app
Not a full contract lifecycle management system
