Where answers come from
Six kinds of source
Statutes and regulations
Federal law, all 50 states, DC and Puerto Rico, from CaseRead’s public law database. Looked up when you ask, so you read the current text, not a stored copy.
Case law
Opinions from the Free Law Project, read in full before they’re cited. A question about a state searches that state’s appellate courts; a federal question searches the Supreme Court and the courts of appeals.
Court rules and constitutions
The Federal Rules of Civil Procedure and of Evidence are kept on hand. When the Hallucination Shield checks a rule or constitution citation, it reads the text in CaseRead’s public law database, or a state court’s official rules website in ten states.
Federal publications
Current federal regulations from eCFR, new and proposed rules from the Federal Register, and recent public laws from GovInfo.
Web search
Any answer can search the web when the question calls for it. Deep research runs a web search pass every time before it answers.
Your firm’s files
The documents in your vault, searched beside the law, so one answer can cite your file and the statute together.
