AI Terms Of Service

Anthropic has appointed Robert Mahari as its first Head of Claude for Legal, a newly created role tasked with overseeing product development and commercial strategy for the company's legal AI offering. Mahari, a legal AI researcher and founder of Akiva, joins Mark Pike, Anthropic's associate general counsel who has been leading Claude's legal vertical since the product's formal launch in May 2026. The appointment follows Anthropic's expansion of Claude for Legal through practice-area plugins and integrations with legal tech platforms, including a partnership with Thomson Reuters to connect Claude with CoCounsel Legal.

Vendor contracts are being urgently reclassified as AI risk vectors. In 2026, corporate counsel are discovering that SaaS and AI vendors have embedded contractual language permitting them to train, fine-tune, and evaluate proprietary models on customer data without explicit consent. What vendors historically labeled "service improvement" provisions are now recognized as mechanisms for secondary data exploitation. Law firms including Kilpatrick Townsend, Consilium Law, and SiLaw have published redlining guides instructing clients to demand explicit "no training," "no commingling," and "no retention" clauses in master service agreements.
