Deep Research, a groundbreaking innovation by Thomson Reuters, is redefining the domain of legal research. Discover Deep Research.
Deep Research, a new AI-native legal research system, is set to revolutionize the way lawyers conduct research. Launched by an unnamed company, Deep Research employs Westlaw's exclusive research toolset and is designed for long-document comprehension, multi-step reasoning, and structured tool usage15.
What Makes Deep Research Unique?
Unlike other AI-assisted legal research systems, Deep Research is an AI-native, agentic system specifically trained and instructed by experienced attorneys to use Westlaw’s proprietary tools and curated legal content. It creates and executes multi-step research plans with transparent reasoning, delivering comprehensive, citation-backed reports1.
Deep Research offers unique features for Westlaw and CoCounsel users. These include AI agents trained to use Westlaw’s proprietary tools such as Key Numbers, KeyCite, Precision Research classifications, and statute annotations, enabling highly precise and domain-specific legal research1.
The system also boasts multi-step agentic workflows that plan, review, and strategize research like expert attorneys, supporting complex project completion rather than isolated tasks1. Detailed, structured reports that trace the AI’s reasoning and provide sources help users move from question to comprehensive research strategy faster with minimized hallucination risk3.
Seamless Integration and Continuous Improvement
Deep Research is seamlessly integrated with CoCounsel Legal, allowing users to move between research, case strategy, document drafting, and analysis within one continuous AI-enhanced workflow2. The system is designed to constantly update and gain new capabilities as AI breakthroughs become available, ensuring users have access to state-of-the-art legal AI tools2.
