Anthropic expands Claude's AI tools for law firms, lawyers

Anthropic launched expanded legal-focused features for its Claude AI assistant, integrating Thomson Reuters' Westlaw and CoCounsel platforms, as well as tools from Harvey, Box, Everlaw, and DocuSign to enhance legal research and document management. The update includes 12 new legal practice plug-ins and aims to strengthen AI adoption in the legal industry amid growing competition among tech firms targeting professional services.
Anthropic, a San Francisco-based AI company, announced on May 12 an expanded suite of legal-focused tools for its Claude AI assistant. The update enables law firms and customers to securely connect Claude with third-party platforms like Thomson Reuters for legal research, document management, and practice guides. New integrations include access to Thomson Reuters' Westlaw Primary Law database and its CoCounsel AI platform, which provides 'fiduciary grade' legal research tools. Thomson Reuters also confirmed the integration of its Westlaw-enabled CoCounsel platform with Claude, allowing users direct access to advanced legal research capabilities. The partnership aims to embed CoCounsel’s tools into professional environments, ensuring lawyers can leverage AI-powered assistance regardless of their workflow. Financial terms of the collaboration were not disclosed. Additional integrations include Harvey’s legal assistant for general inquiries, Box for content management, Everlaw for electronic discovery, and DocuSign for document processing. Anthropic highlighted these connections as part of a broader effort to accelerate AI adoption in the legal sector, citing a recent webinar on Claude’s legal applications that drew over 20,000 registrations. The new release also introduces 12 specialized legal practice plug-ins, such as 'commercial counsel,' 'employment counsel,' and 'litigation associate.' These tools can be deployed within Anthropic’s Cowork platform or embedded into law firms’ internal systems. The update follows Anthropic’s January announcement of plug-ins for Claude Cowork, which sparked investor reactions in data analytics, software, and professional services sectors. Anthropic’s associate general counsel, Mark Pike, emphasized the growing demand for AI in legal work, positioning the company as a leader in professional AI solutions. The expansion reflects broader industry trends as tech firms compete to develop AI tools tailored to information-heavy sectors like law.
