The practice round most hearings never get.

Alone, nobody challenges you. A colleague hasn't read the brief. A firm moot takes three lawyers and a week.

Frequently asked questions

What is Casey?

Casey is an AI practice tool for oral argument. Upload your brief or pick a prepared matter, then argue out loud in your browser while an AI judge questions you by voice. Afterward you get a debrief scored out of 10. Casey is for rehearsal and does not give legal advice.

Who is it for?

Litigators with a hearing coming up: trial and motions counsel, associates building courtroom reflexes, and government lawyers such as prosecutors, AG offices and public defenders. It also suits moot court programs and law students.

Trial or appellate?

Both. There are practice rooms for trial court, family court, the court of appeals and the Supreme Court, and you can practice with benches modeled on real judges. Don't see yours? Request it in the app.

How is it different from ChatGPT?

ChatGPT is a general-purpose assistant. It isn't built to press follow-ups the way a bench does or grade your argument afterward against a rubric. Casey is: the judge reads your brief, questions you out loud, and stays on the question you dodged, and the debrief scores you against a rubric so you know what to fix.
