What is a ai for law firms?

As of October 2026, AI for law firms is software that reads, drafts, answers or files legal work on a firm's behalf: assistants built into practice management systems such as Clio, MyCase and Smokeball, research and drafting platforms built on a legal content library such as CoCounsel Legal and Lexis+ with Protégé, enterprise platforms such as Harvey, and single purpose tools for intake calls, time capture, discovery responses and medical records. It is sold per user, per attorney, per call or by quote on multi year terms. The category divides on a line vendors rarely advertise: whether the output is saved back into the matter record and the document management system, or stays in the vendor's own window for a person to carry across.
