TLDR: C3 Generative AI has dramatically accelerated legal review and contract analysis for a global law firm, reducing analysis time by over 80% and increasing economic margin by 3X. The AI-powered solution provides hallucination-free first drafts of contract analyses in under 30 minutes, enabling attorneys to focus on high-value tasks and benchmark contracts against market standards.
A leading global law firm has successfully implemented C3 Generative AI to transform its legal review and contract analysis workflows, achieving an 80% reduction in analysis time and a threefold increase in economic margin per contract. This advancement addresses long-standing challenges in the legal sector, where contract evaluation traditionally consumed over 15 hours of an attorney’s time and required extensive specialized knowledge.
Prior to adopting C3 Generative AI, the law firm had attempted to develop an in-house generative AI solution. However, this effort failed to meet the necessary accuracy standards and struggled with frequent ‘hallucinations’—a common pitfall in early AI implementations. Recognizing the need for a robust and reliable solution, the firm partnered with C3.ai for a 12-week production pilot.
The C3 Generative AI solution was designed to streamline legal due diligence by synthesizing information across contracts, answering analysis questions with full source traceability, and enabling collaborative review workflows. Key innovative generative AI techniques employed include section-based chunking for pinpointing relevant sections and a transient vector store for efficient retrieval of information. This ensures that AI-generated answers are accurate and verifiable.
According to a partner at the law firm, the initial legal reviews performed by C3 Generative AI are ‘equivalent to the work of a first-year attorney.’ This allows experienced attorneys to dedicate their expertise to the more complex and intricate aspects of contracts, significantly enhancing overall productivity and efficiency. The application delivers a first draft of contract analysis in less than 30 minutes, a stark contrast to the previous 15-hour manual process. This not only frees up attorney time for high-value tasks but also serves as a valuable educational tool during an attorney’s 18-month contract analysis training.
Beyond accelerating initial reviews, C3 Generative AI also provides advanced benchmarking capabilities. The system extracts key terms from historical contracts, structuring them into a comprehensive database. This enables attorneys to quantitatively identify market standards, compare new contracts against user-defined populations, and assess market conformity. This feature is crucial for surfacing gaps in contracts and informing counterparty negotiations, leading to more favorable outcomes for clients.
