Wilson Sonsini’s Neuron AI agent hits 92% accuracy on commercial contract review

Cloud services companies depend heavily on commercial agreements to do business, and contract work is a major bottleneck for in-house counsel. Wilson Sonsini wanted to bring its technology-transactions expertise to clients earlier in their lifecycles—helping them get to revenue faster—while keeping cost predictable.

The firm added an attorney-supervised, AI-enabled fixed-fee commercial contracting offering to Neuron, its proprietary platform. A proprietary-playbook AI agent proposes highly accurate, explainable revisions to cloud services agreements, then Wilson Sonsini attorneys review each contract under a lawyer-in-the-loop model.

In extensive internal testing, the AI agent on its own identified issues and applied playbook positions with 92% accuracy, with the firm noting that figure can still improve. The offering is live for cloud services agreements, with expansion planned to terms of service, NDAs, and other revenue-related commercial contracts.

• • Pairing a proprietary playbook with lawyer-in-the-loop review can deliver explainable AI contract revisions while preserving attorney accountability.
• • Fixed-fee packaging of AI-assisted commercial contracting can address client demand for speed, accuracy, and cost predictability.
• • Starting with a focused agreement type (cloud services) and expanding outward is a practical path for firm-built legal AI platforms.
