In a significant development for legal professionals, LexisNexis and Thomson Reuters have unveiled their latest generative AI legal assistant offerings: Protégé and CoCounsel 2.0, respectively.
Thomson Reuters, capitalizing on its acquisition of the CoCounsel legal assistant initially developed by Casetext and its subsequent plans to deploy it across all its product lines, has introduced a “supercharged” version called CoCounsel 2.0. According to Thomson Reuters, CoCounsel 2.0 is designed to work three times faster than its predecessor, offering swift answers in seconds rather than minutes. It promises improved intuitive operation, better understanding of customer communication styles, and thorough, nuanced results by considering the full context of sophisticated requests. Moreover, CoCounsel 2.0 will be integrated with Thomson Reuters products like Westlaw Precision and Practical Law and Microsoft 365 applications such as Word, Teams, and Outlook. The assistant will also be accessible from document management systems like iManage, NetDocuments, and SharePoint, and will offer advanced capabilities like CoCounsel High Throughput Beta for automating large-scale document reviews with human-level accuracy.

LexisNexis, on the other hand, announced the commercial preview of its Protégé Legal AI Assistant, part of the third generation of its Lexis+ AI platform. Emphasizing personalization, Protégé is described as a private, trusted assistant unique to each legal professional. LexisNexis highlights its acquisition of Henchman, a Belgium-based contract drafting technology company, as key to enhancing Protégé’s ability to provide deep insights by mining a law firm’s internal work product. Protégé is expected to support a range of AI-enabled tasks, from leveraging internal firm data for deep insights to comprehensive task management, including building timelines, conducting statutory horizon scanning, drafting documents, and conducting legal research. Its integration extends to Microsoft 365 products, aiming to reduce application switching time and increase efficiency. The assistant’s deployment across various LexisNexis products and its upcoming features for 2025 are detailed here.
These advancements mark a crucial step forward in the legal profession’s integration of AI to enhance productivity and accuracy. Both Protégé and CoCounsel 2.0 illustrate their developers’ commitment to addressing the evolving needs of legal professionals through cutting-edge AI technology.
