DeepJudge launches ChatGPT Enterprise plugin for legal teams

DeepJudge on September 17, 2026 introduced a ChatGPT Enterprise plugin that lets law firms and in-house legal teams tap internal precedent, work product and judgment inside AI workflows. The move aims to bring governed institutional knowledge into legal research, drafting and deal work without migrating data.

Why it matters: - Legal teams often struggle to use internal knowledge at the moment they need it. - DeepJudge’s plugin is meant to surface governed institutional context inside ChatGPT Enterprise, so lawyers can work with precedent, prior decisions and firm judgment already stored across internal systems. - The product could make AI output more relevant for legal research, drafting and complex deal work by tying answers to a firm’s own materials.

What happened: - DeepJudge announced a plugin for ChatGPT Enterprise on September 17, 2026. - The plugin is available starting today in ChatGPT Enterprise. - DeepJudge said the companies will work on deeper workflow integrations over the coming months with leading law firms. - The plugin is designed to bring the knowledge, experience and judgment of law firms and in-house legal teams into AI-powered legal work.

The details: - DeepJudge is an institutional intelligence platform built for legal AI. - The platform finds, analyzes and synthesizes knowledge across an organization’s existing systems. - DeepJudge respects permissions, ethical walls and governance. - The system does not require data upload, migration or restructuring. - ChatGPT users can use the plugin to draw on precedent, work product, prior decisions and collective expertise across their organization’s systems. - The plugin includes links back to underlying materials. - A lawyer negotiating an acquisition could ask ChatGPT how the firm handled a similar issue in prior deals, and ChatGPT can use DeepJudge to locate and analyze relevant institutional knowledge. - OpenAI GM for Legal Industry Jason Boehmig said the partnership is aimed at turning each firm’s expertise into AI lawyers can use every day. - DeepJudge CEO and co-founder Paulina Grnarova said context is becoming the defining advantage in enterprise AI. - Grnarova said the plugin lets legal teams put institutional intelligence to work with OpenAI’s most capable models. - DeepJudge says its platform helps legal teams find and analyze information, uncover insights across matters and apply what the organization already knows to new work. - The company says it is trusted by Holland & Knight, Greenberg Traurig, ArentFox Schiff, Cozen O’Connor, CMS and Homburger, among others. - DeepJudge also provided its website as More information. - DeepJudge listed media relations contact information and a LinkedIn page at DeepJudge on LinkedIn.

Between the lines: - The launch points to a legal AI market moving beyond generic answers and toward firm-specific context. - DeepJudge is positioning governed internal knowledge as the differentiator, not just model quality. - The OpenAI collaboration gives DeepJudge distribution inside an enterprise AI product already used by legal teams.

What's next: - DeepJudge and OpenAI plan to build deeper workflow integrations over the coming months. - The companies will do that work in collaboration with leading law firms. - The near-term test is whether the plugin can fit into day-to-day legal research, negotiation and drafting without adding friction for users.
