Ropes & Gray develops AI for transactional diligence with OpenAI

Ropes & Gray is developing artificial intelligence tools for transactional diligence with OpenAI, according to the firm’s published materials. The effort is aimed at helping lawyers review grouped documents, summaries and reports before advising clients, underscoring how legal teams are using AI to organize large deal data sets without replacing attorney judgment.

Evidence and context

The source material says the work is focused on transactional diligence, a process that can span finance, tax, intellectual property, data privacy, regulatory, employment, antitrust, anti-corruption, international risk and litigation issues. Ropes & Gray’s M&A practice describes that broader diligence approach as an integrated review across those disciplines, while its life-sciences diligence offering says it provides regulatory diligence, issue assessment, remediation advice and help negotiating transaction terms that reflect diligence findings.

Related firm announcements show the AI effort is part of a broader transaction-focused platform. On 16 September 2026, Ropes & Gray said it was developing an AI-powered diligence tool with OpenAI to deliver what it called comprehensive deal intelligence for clients. The firm also reported high rankings in Mergermarket’s global M&A and private equity league tables on 9 July 2026, and said on 3 February 2026 that it advised Ares’ private equity group and DaVita in a strategic investment in Elara Caring.

The available material does not disclose product pricing, deployment timing, performance metrics or client adoption figures. It also does not provide an independent assessment of the tool’s effectiveness. The evidence available here supports only that Ropes & Gray is building the system with OpenAI and positioning it for use in diligence workflows before lawyers advise clients.
