Clio Duo is an AI-powered legal assistant built into Clio's practice management platform that helps lawyers work more efficiently by drafting legal documents, summarizing case information, identifying next steps, and answering questions about client matters — all with full context from the firm's own Clio data. Unlike generic AI assistants, Clio Duo understands legal workflows and integrates directly with case files, contacts, and documents already in the system. Law firms using Clio experience dramatically faster document preparation and matter management when Duo's AI operates with real case context rather than hypothetical scenarios.
