Cross-examination
Short leading questions, one compound question, a sustained objection.
For law schools, mock trial and advocacy programs
Every student gets a witness, a judge and a jury, on their own time.
Between class sessions, students run a direct, a cross, a voir dire or a deposition against an AI that answers like a real witness and rules like a real judge, from the case file you choose. A jury decides. A coach quotes the question that cost them. You assign the exercise and see the scores.

How a pilot works
Live in an afternoon
- Create your program in two minutes. You start on the Law package with 25 seats and 1,000 rounds (exchanges with the AI) shared by the group, free for 30 days, no card.
- Share one link with the class. Students tap it and are in. Works on phones; no install.
- Assign the exercise. "Cross-examine Officer Corbett in State v. Linden, strict judge, by Thursday." See who ran it and how they scored, then teach to the weakest dimension.

Data and security
What happens to your students' sessions
- Audio is never stored. Speech is turned into text by the browser (Chrome, Edge or Safari, under that company's terms). We receive only the text and never record or store audio.
- Supervisors see scores, not transcripts. Trainers see scores, session counts and weakest skills. Sessions are private to the person who ran them unless they choose to publish one.
- Not used for training AI. We do not use sessions to train AI models, and we do not sell personal data.
- Who processes data. Microsoft Azure (AI responses and text-to-speech, United States), Cloudflare (hosting, database, security), Stripe (payments; we never see card numbers), Resend (email), and HeyGen LiveAvatar for photoreal video opponents on the Champion and Elite plans.
- Deletion. Anyone can delete a single session, or their whole account and every session in it, from the app. Deletion is permanent.

FAQ
Questions, answered
Which cases are included?
Real criminal, civil and appellate cases with full fact patterns, original practice cases, and your own: describe the case in about a page (the key facts, the witness, the charge or claim) and the judge, witnesses and jury work from it. For clinic matters, leave out real client names and case numbers.
What do instructors see?
Scores on four dimensions per exercise, session counts, best scores and where the class is weakest. Never transcripts; students own those.
How accurate are the rulings?
The judge applies the standard rules of evidence and names the ground. It does not know your league's special rules, and the scorecards say it is practice, not legal advice.
What does it cost?
$6 per student per month with 150 rounds each. Departments and clinics can be billed centrally. Pilot first, free.
How can we pay?
Card, or invoice/PO (net 30), monthly or annual. 30 students for a year: $2,160. Email support@getadversaryai.com for an invoice.
Can students use it for OCI and clerkship interviews?
Yes. The interview mode takes the firm, the role and the level, and the career-fair mode rehearses the thirty-second pitch.
