Live witness examination, scored.

Build confidence examining realistic witnesses, before it counts.

SimDuo lets you examine a live AI witness out loud — cooperative, neutral, or hostile — then scores your performance against a rubric and shows you exactly what to fix.

Cost and Risk

Practice should happen before client outcomes are on the line.

In-person witness simulation runs about $3,500 for 20 sessions. That's before travel, scheduling, or attorney time. SimDuo gives you the same practice for about a tenth of the cost.

Set up the exam.

Pick a witness and temperament: cooperative, neutral, or hostile. Then review the case file.
