Heat Map Visualization: Clusters documents for prioritized review, enabling legal teams to focus on high-risk areas. Dentons reduced a 180,000-document review from two months to two weeks using this functionality[132].

Salesforce Integration: Enables contract generation directly from CRM opportunities, addressing corporate legal workflow requirements[129].

Performance Validation Through Customer Outcomes

Customer evidence consistently demonstrates substantial time savings, though organizations should verify performance expectations for their specific use cases:

• Avianca completed a 1,000-document compliance review in three hours, representing significant improvement versus manual methods[122]
• Bird & Bird reviewed 200,000 employee contracts with two lawyers in three weeks, compared to eight lawyers required for manual processing[131]
• Deloitte achieved 50% time savings on BT's 4,500-document EU compliance project[64]

Language Processing Capabilities: The platform processes English, Spanish, and Portuguese documents, addressing multinational legal operations[122][123].

Documented Limitations

Customer feedback and implementation evidence reveal specific constraints legal professionals should consider:

Microsoft Word Integration: Limited compatibility with Word-based workflows creates friction for teams heavily dependent on document markup processes[126].

Context Interpretation: The system faces challenges with ambiguous phrasing and implied obligations, requiring human oversight for strategic contract amendments[123][127].

AI Reliability Considerations: Industry-wide challenges with AI accuracy necessitate human validation processes, particularly for complex negotiation contexts[120].

Customer Evidence & Implementation Reality

Documented Success Patterns
