ChatLaw

ChatLaw is a chat based legal assistant for federal and 13 state jurisdictions that answers research questions and drafts briefs, motions and appeals from typed prompts or attached files, with a Matter workspace for subscribers.

ChatLaw is a web based legal assistant that answers legal questions and drafts court documents in a chat interface. Users type or attach a question, optionally upload files such as an opposing brief or a court decision, and the system returns analysis or a written draft. The homepage lists federal jurisdiction alongside 13 state courts (New York, Texas, California, Florida, Pennsylvania, New Jersey, Illinois, Ohio, Connecticut, Washington, Georgia, Virginia and Michigan), so a question can be framed against the law of a specific forum rather than a generic national answer. The sample sessions show the scope: writing a brief in opposition to an amicus brief, appealing a decision with Texas Supreme Court cases, replying to a prosecution motion in limine, and arguing a bankruptcy question about preferential payments and secured status. The tool is built for practicing attorneys, paralegals and law students who want a first pass on research or a skeleton draft before doing their own cite checking. Subscribers get a Matter workspace where multiple files can be uploaded, a document summary can be generated from the Matter dropdown menu, and chat history is tied to the signed in account. Users without an account can still run a question in a trial session, but the history is not saved. The interface also links to Colit, a separate drafting service where a human team produces motions and briefs, and to a Substack newsletter covering AI and legal writing. In practice, ChatLaw sits between general purpose chatbots, which are weak on citation and jurisdiction, and legal research databases, which are strong on authority but light on drafting. It is not a substitute for a citator, and nothing on the homepage indicates that citations are verified or that the output is reviewed by a lawyer. Firmer ground comes from attaching the source documents and treating the response as a draft to be edited. There is no stated pricing, integration list or support page on the homepage, so those details need to be confirmed directly with the vendor.
