Sullivan & Cromwell builds Agreement Analyzer with OpenAI for contract review

Sullivan & Cromwell built Agreement Analyzer with OpenAI, a tool that helps its lawyers find issues in draft agreements. Partner John Savva started it as a single-user proof of concept built with Codex, then worked with OpenAI to improve output quality, speed it up with parallel processing and make it usable by many lawyers at once. A lawyer uploads a draft, adds chosen precedents and a playbook of firm and client positions, and the tool runs several review passes from different angles and returns a memo plus proposed tracked changes for the lawyer to accept or reject. It runs on the firm's precedents, its negotiating playbooks and ChatGPT Enterprise. OpenAI's post gives no figures on time saved or accuracy. Sorted take: the useful idea is the design, with firm precedents and playbooks as inputs and every suggestion left for a human to approve, not the brand names.
