Clio is the world's leading legal practice management software — used by over 150,000 legal professionals across 100+ countries. It handles the full law firm workflow: client intake, matter management, time tracking, billing, document management, client portal and AI-powered drafting.
Clio Duo is the AI layer built into Clio — it drafts documents, summarises matters, answers questions about your cases and automates routine tasks using your firm's own data. Unlike standalone AI tools, Clio Duo has context about your actual clients and matters, making its outputs far more relevant.
For small and mid-size law firms looking for one platform that handles everything, Clio is the clearest choice in the market — it has the largest ecosystem of legal app integrations (250+) and the most mature feature set of any practice management tool.

Clio Duo is the AI assistant built into Clio — it can draft documents, summarise matters, generate billing narratives and answer questions about your cases using your firm's own data. Because it has context about your actual clients and matters, it produces more relevant outputs than a standalone AI tool like ChatGPT.
