Sullivan & Cromwell brings legal expertise into agreement review
What happened
Sullivan & Cromwell teamed with OpenAI to create Agreement Analyzer, an AI tool that reviews draft agreements by comparing provisions to firm precedents, negotiating playbooks and market practice, then producing a memorandum and suggested tracked changes. The system was built as a single‑user proof of concept with Codex and later expanded for multiple lawyers, integrating ChatGPT Enterprise and parallel processing. Partner John Savva says the tool lets lawyers focus on judgment‑heavy areas while the AI handles deep analysis of complex clauses. It offers transparent sourcing for any claims it makes and can run adversarial agent reviews to flag risks and ambiguities. The firm plans to explore more task‑specific AI tools as reasoning models improve.
Why it matters
For ordinary readers, this means legal services could become faster and more thorough, potentially lowering costs and improving contract quality. It also shows AI moving from simple admin tasks to substantive legal analysis.
Reality check
An automated, sceptical read of the sourceIncremental. The tool builds on existing AI capabilities and adds workflow integration, but it is an evolution rather than a fundamentally new technology.
Is this a big deal?
