Anthropic expands Claude with legal research tools and specialized practice plug-ins
Anthropic released an expanded suite of Claude AI features for lawyers on Tuesday, including direct connections to Thomson Reuters' legal databases, document management platforms, and 12 new practice-specific plug-ins designed for corporate counsel, litigation, and employment law.
The San Francisco company said existing Claude customers can now connect securely to Thomson Reuters' Westlaw Primary Law database and Practical Law guides, as well as platforms including Harvey, Box, Everlaw, and DocuSign. The new tools address intensifying competition among technology companies to build professional AI products as the legal sector accelerates adoption.
What lawyers get
The 12 new legal practice plug-ins include specialized roles: "commercial counsel," "employment counsel," "litigation associate," and "law student." Firms can deploy these directly in Anthropic's Cowork platform or embed them into their own systems.
Thomson Reuters also integrated its CoCounsel platform-an AI tool for legal research-with Claude. This connection lets CoCounsel users access the platform's research capabilities directly within Claude, though Thomson Reuters emphasized the integration doesn't replace CoCounsel's standalone features.
Mark Pike, associate general counsel at Anthropic, told Reuters the company is seeing strong demand. A recent webinar on how legal teams use Claude drew more than 20,000 registrations.
Market context
The announcement follows Anthropic's January release of Claude Cowork plug-ins, which triggered a major stock selloff among data analytics, professional services, and software companies. Technology firms are racing to develop AI tools for information-heavy industries where adoption is accelerating.
Thomson Reuters did not disclose financial terms for the integration.
