Sullivan & Cromwell has developed Agreement Analyzer, an AI-powered tool that integrates the firm’s legal expertise, precedents, and negotiating playbooks to enhance contract review. Built initially as a proof of concept with Codex and refined with OpenAI, the tool enables lawyers to input draft agreements, add selected precedents and playbooks, and receive multi-perspective analysis. It identifies potential issues, synthesizes outputs, and returns memoranda with tracked changes for lawyer review.
Partner John Savva emphasizes that the tool does not replace lawyers but allows them to focus on high-judgment tasks by providing deeper analysis and greater access to authority. The system ensures transparency by making sources and uncertainty visible, using adversarial AI agents to challenge conclusions and highlight verified, dismissed, or unverified findings. Sullivan & Cromwell continues to explore AI tools for specific legal tasks, with Savva citing advances in reasoning capabilities via GPT‑6 Astra as a key enabler for supporting more of the research and writing process.
