We are at the forefront of a groundbreaking transformation in how legal professionals engage with AI. This change is not just on the horizon; it’s happening now, and at breakneck speed.
For the past few years, legal AI has been all about prompting. Ask a question, get an answer; refine your prompt, get a better response. It’s been helpful, but it still required you to drive every interaction, manage every step, and verify every output. That’s changing in a big way.
CoCounsel Legal represents something entirely different: it unifies legal research, workflow automation, intelligent document management, and AI-powered legal assistance into one seamless solution. This is the most advanced AI offering to date from Thomson Reuters, and it is designed to help legal professionals move from merely prompting and into true AI transformation.
The Foundation for Professional-Grade Agentic AI
True agentic AI in legal practice requires three essential components: advanced reasoning models, comprehensive legal content and tools, and expertise from thousands of domain experts. Thomson Reuters has meticulously developed and enhanced these capabilities over decades, a key differentiator that other providers simply cannot imitate.
Part of CoCounsel Legal, Deep Research, grounded in Westlaw content, demonstrates what becomes possible when these elements come together. This isn’t AI that mimics legal thinking; it reasons through complex legal problems with the depth and rigor that legal professionals require.
Customer Value Through Reasoning and Transparency
Deep Research in CoCounsel Legal stands out by providing value through transparency. Legal professionals need more than just answers; they need to understand the reasoning behind those answers. This transparency is essential for professional accountability. By understanding how AI reaches its conclusions, you can trust its work and build upon it with confidence.
“Thomson Reuters latest integration of advanced AI models into its core platforms marks an encouraging step forward in legal technology,” said Colleen Nihill, Chief AI & KM Officer at Morgan Lewis. “Deep Research stands out for its ability to reason through legal questions rather than simply return search results. When faced with a complex issue, it can generate a research plan, explain its logic, and deliver a structured report. This level of transparency is essential to maintaining the oversight and trust lawyers need to confidently adopt AI in practice.”
From Task Completion to Strategic Delegation
The guided workflows in CoCounsel Legal take this concept even further. Rather than handling individual tasks, these multi-step agentic workflows tackle entire legal processes – from drafting complaints to reviewing deposition transcripts. Each workflow integrates legal content, applies structured reasoning, and ensures human oversight by design.
As our Chief Product Officer David Wong said:
“This is where AI starts to feel less like a tool and more like a teammate. Guided workflows are how professionals start delegating – not just prompting – and that’s a huge leap forward … “
This transformational shift from prompting to delegating isn’t just about efficiency, either; it’s about enabling legal professionals to focus on what they do best: strategic thinking, counseling, and complex problem-solving. With AI handling foundational research and routine workflows, lawyers can dedicate more time to high-value work.
The Future of Legal AI
Agentic AI is redefining the relationship between legal professionals and technology. We’re moving from AI as an adjunct to AI as an indispensable part of the legal process, driving real outcomes in litigation, transactional work, and regulatory analysis. CoCounsel Legal isn’t just an advancement; it’s a fundamental shift in how legal work gets done.
The future of legal practice isn’t about humans versus AI – it’s about humans empowered by AI they can delegate to and trust. With CoCounsel Legal, that future is here today.
