Thomson Reuters adds new agentic AI capabilities in CoCounsel Legal

Thomson Reuters, a global content and technology company, is introducing three new capabilities now available in beta releases for CoCounsel Legal—including agentic workflows that independently execute complex legal tasks, customizable workflow plans enabling lawyers to create and share across practice groups, and bulk document review of up to 10,000 documents. 

According to the company, these announcements will expand the organization’s agentic capabilities and are being designed with a next-generation agentic framework marking a substantial progression in the application of AI for legal professionals.

“Legal technology is moving from narrow solutions to agentic systems on a fast path to generalized intelligence—and the pace is only going to accelerate,” said Raghu Ramanathan, president, Legal Professionals, Thomson Reuters. “With CoCounsel Legal, we're reimagining the core of legal work with market-leading technology grounded in trusted, authoritative content—all built to scale safely. Our commitment is simple: help our customers thrive in this era of AI transformation and be at the forefront of the industry as the future arrives—these capabilities are another step forward in making that vision real.”

The beta release of CoCounsel Legal's bulk document review introduces a powerful solution to address the review of large document sets—one of the most time-consuming tasks in legal practice. This capability enables users to upload extensive collections of documents and receive organized, sortable results in a user-friendly table format, the company said. 

Building toward increasingly advanced artificial intelligence with progressively capable agents, the new CoCounsel custom workflow betas will be available in two phases. 

In the first phase, CoCounsel Legal will independently plan and execute complex, multi-step legal workflows. Legal professionals will be able to initiate any workflow, from analysis to document creation, with a simple prompt. CoCounsel Legal will interpret the request, determine the optimal approach and execute the complete workflow using Thomson Reuters authoritative Westlaw and Practical Law content alongside the firm's institutional knowledge, the company explained.

With the second phase, legal professionals will have access to a customizable workflow builder that will allow them to create, save and share their own workflows within CoCounsel Legal capitalizing on the trusted content and solutions from Thomson Reuters as well as the firm’s knowledge. Additionally, this facilitates the development of repeatable, law firm-specific processes and supports reusability across teams—ensuring consistency while capturing institutional knowledge and best practices.

“What sets these features apart is not just what they do, but how they do it. They enable legal professionals to move beyond pre-built solutions to create personalized, repeatable workflows where CoCounsel autonomously plans and executes the requisite steps using our solutions and authoritative content,” said Ramanathan.

These new features expand CoCounsel Legal’s capability to handle the broadest range of legal work with precision. These enhancements are being introduced through early beta programs and will become available over the coming months. 

Additionally, multiple enhancements to Thomson Reuters legal solutions begin rolling out to customers in November 2025 across Deep Research, Litigation Document Analyzer and new guided workflows from Practical Law.
