Definely has integrated its contract review technology into ChatGPT Enterprise through OpenAI for Law, providing lawyers with specialized verification tools within their AI workflow. This partnership addresses the growing need for independent review of AI-generated legal documents.
TL;DR
- Definely's integration with ChatGPT Enterprise allows lawyers to review and validate contracts without leaving their AI workflow.
- The partnership highlights the shift in legal AI from drafting to verification, with Definely positioning itself as an independent review layer.
- Definely's tools are already used by thousands of lawyers globally, including major law firms and in-house legal teams.
What happened
Definely, a London-based legal technology company, has partnered with OpenAI to integrate its contract review technology directly into ChatGPT Enterprise. This integration is part of OpenAI for Law, a service aimed at providing lawyers with advanced legal verification tools within their existing AI workflow.
The integration uses the Model Context Protocol (MCP) to make Definely's contract review capabilities available directly within ChatGPT Enterprise. Lawyers can use these tools to perform defined-term validation, search their firm's precedent bank, conduct structural proofreading, and automatically generate issues lists without leaving the ChatGPT environment.
Definely's tools were previously centered around its Microsoft Word add-in. This new integration expands the company's presence into enterprise AI workflows while maintaining its focus on contract analysis and review.
Why it matters
The partnership reflects a broader change in how legal professionals are beginning to use generative AI. As drafting becomes faster, legal teams may increasingly need technology that can inspect the structure and implications of documents created or modified by AI.
Definely positions itself as an independent review layer within the legal process. The company argues that the same system responsible for creating legal content should not necessarily be the only system responsible for validating it.
This integration could become increasingly important as law firms, corporate legal departments, insurers, and regulators scrutinize how AI-generated legal work is reviewed and approved. By putting specialist contract review capabilities directly inside ChatGPT Enterprise, Definely is attempting to address one of the next major workflow challenges created by generative AI.

Context
The legal industry is increasingly adopting generative AI to accelerate drafting processes. However, the verification and validation of AI-generated legal documents remain critical steps in the legal workflow.
Definely's integration with ChatGPT Enterprise reflects a broader trend in the legal technology sector, where companies are focusing on providing specialized tools for reviewing and validating AI-generated content.
As legal teams consolidate more research, drafting, and analysis inside AI-enabled work environments, the need for independent review layers becomes more pronounced.
