Upload the record you are preparing — the briefs, the decisions below, the passages you will be pressed on. Choose from more than 100 judges. Each AI jurist model is fine-tuned on that judge's public decisions, opinions, and speeches; each voice is recreated from public recordings. Hear that judge's question in their own voice, then answer aloud through every follow-up.
