CoCounsel Legal review

CoCounsel Legal is the Thomson Reuters answer to firm-wide legal AI, and its main advantage is the content behind it. The complete plan bundles Westlaw Advantage for research, the Practical Law Dynamic Tool Set for transactional guidance and CoCounsel Essentials for document work. Essentials alone covers the daily drafting and review tasks: Tabular analysis across many documents, Draft and Modify Clauses, Contract Playbooks, Knowledge Search and a Prepare for a Deposition workflow, available on the web and inside Microsoft Word. Thomson Reuters sells plans online to firms under 10 attorneys, with CoCounsel Essentials listed at $292.50 per attorney per month on a 3-year term against a $360.00 list price, with separate plan pages for law firms, corporations and government, and asks larger firms to contact a sales rep. The trade-off is cost and lock-in: the strongest version assumes a Westlaw subscription, and prices change with seat count and term length. For firms already on Westlaw, it is the most complete research and drafting package on this list.
