On June 2, 2025, Thomson Reuters unveiled its next-generation Agentic AI systems, beginning with the launch of CoCounsel for tax, audit, and accounting professionals. Unlike traditional AI that only responds to direct prompts, Agentic AI is designed to autonomously plan, reason, take action, and adjust its course of action as needed - all within the workflows professionals already rely on. These systems are built to meet the high standards of accuracy, transparency, and accountability required in legal, tax, and compliance work.
The Thomson Reuters Agentic AI Platform stands out due to its deep integration into flagship products such as Westlaw, Checkpoint, and Practical Law, as well as the incorporation of capabilities from its recent acquisition, Materia, a startup specializing in AI copilot systems. Rather than introducing standalone tools, Thomson Reuters is re-architecting its platforms, allowing these agentic systems to perform complex, multi-step tasks from reviewing documents to generating filings using trusted content, purpose-built tools, and domain-trained models.
The first live implementation, CoCounsel for tax and accounting, enables professionals to automate time-intensive processes such as client file review, state-by-state compliance checks, and memo drafting. Early adopters have reported significant efficiency gains, what once took days now takes hours. This AI agent unifies internal firm knowledge, IRS codes, and authoritative databases into a single intelligent workspace, operating with contextual understanding and human oversight.
Looking ahead, Thomson Reuters plans to extend agentic capabilities into legal, risk, and compliance domains, with tools to support intelligent drafting, deposition analysis, employment policy generation, and more. These new systems are governed by human-in-the-loop oversight, powered by transparent reasoning, and built on a foundation of 20B+ documents, 4,500+ subject matter experts, and deep partnerships with providers like OpenAI, Anthropic, AWS, and Google.
This launch marks a strategic inflection point in Thomson Reuters’ broader transformation into a global legal tech powerhouse, reinforcing its leadership in AI innovation tailored for high-stakes professional environments. As Chief Product Officer David Wong stated, “Agentic AI isn’t a buzzword, it’s a new blueprint for how complex work gets done.” With this platform, the company sets a new benchmark for what AI can achieve when developed with expert insight, enterprise-grade security, and real-world application in mind.
