Thomson Reuters Launches CoCounsel Knowledge Search Tool

Thomson Reuters launched CoCounsel Knowledge Search on July 9, 2025, enabling legal professionals to search across multiple document repositories simultaneously. The AI-powered tool accesses content from HighQ, iManage, NetDocuments, SharePoint, OneDrive, Westlaw, Practical Law, and third-party sources through a unified interface.

This development addresses a critical workflow problem where legal professionals waste time searching separate document management systems, downloading files, and transferring them between platforms. The fragmented nature of knowledge management systems creates inefficiencies that directly impact productivity and billable hours.

Unified Search Across Multiple Platforms

CoCounsel Knowledge Search integrates with major document management systems used by law firms and corporate legal departments. The tool leverages GPT-4.o technology to deliver search results without requiring users to leave their current CoCounsel workspace.

Legal professionals can now access Thomson Reuters content from Westlaw and Practical Law alongside their internal documents and third-party sources. This eliminates the need to switch between multiple applications during research and document preparation.

Enhanced Security and Partnership Strategy

The system maintains data security by keeping information within the customer's domain while providing AI-powered search capabilities. This approach ensures compliance with legal industry security requirements and confidentiality protocols.

Thomson Reuters expanded its strategic partnership with Syncly to support deeper collaborative product development. The partnership will include additional integrations with eDiscovery, practice management, and contract lifecycle management systems.

Workflow Integration and Future Enhancements

"Customer centricity is a value Thomson Reuters lives and breathes, and our integrated solution directly answers the evolving needs of legal professionals," said Rawia Ashraf, head of Product, CoCounsel Transactional and Corporates at Thomson Reuters.

The tool addresses the specific challenge of scattered documents across multiple systems by providing seamless access to organizational content repositories. Users can search, access, and manage content from various sources without switching between different platforms.

"With CoCounsel Knowledge Search, users can search where they are currently working in CoCounsel, alleviating the necessity to search their various document management systems, find and download documents, and then move them to the required portal," Ashraf explained.

Future enhancements will include agentic search capabilities that allow users to ask interpretive questions directly within the CoCounsel chat interface. The tool will also integrate with Microsoft's ecosystem and other Thomson Reuters productivity tools.

Market Impact and Accessibility

CoCounsel Knowledge Search requires existing access to Westlaw Edge UK for customers who want to display Westlaw content. The tool does not bypass existing licensing requirements but provides a more efficient way to access subscribed content.

The launch represents Thomson Reuters' continued investment in AI-powered solutions for legal professionals. The company aims to eliminate workflow duplication and unlock the full value of institutional knowledge through integrated technology platforms.

Knowledge management systems in the legal industry typically lack basic integration capabilities, forcing professionals to work across disconnected platforms. This fragmentation creates bottlenecks in research, document review, and client service delivery.
