Everything stays on your iPhone. Built for attorneys, law students, paralegals and anyone who needs the actual text of the law, fast. ASK A QUESTION. GET THE STATUTE. Type a question in plain English: "What does 42 U.S.C. § 1983 say?" or "Which federal rules cover data privacy?" The AI assistant runs entirely on your device and answers with sources from the built-in library. Every answer shows you where it comes from, so you can read the primary law yourself. No queries leave your phone. 11 MILLION+ DOCUMENTS, ONE SEARCH • US Code: every title of federal statutory law • Code of Federal Regulations: all active titles, organized by agency • Supreme Court: 940,000+ opinions, from the founding to today • Federal courts: 10 million+ circuit and district court opinions • Congress: bills and resolutions from the 118th and 119th Congress • Federal Register: rules, proposed rules and agency notices • State statutes: growing coverage, state by state Search everything at once or filter by statutes, cases or Congress.
