Practice openings, witness examinations, objections, closings, and appellate arguments with AI simulations and structured feedback. Build oral advocacy skills between classes, coaching sessions, and live practice.

Who is TrialSim for?
TrialSim puts you in a realistic courtroom simulation — scored on PRESENCE, our proprietary framework inspired by how judges and supervising attorneys evaluate real advocacy. Log the reps before the pressure hits.

Step into realistic courtroom simulations across all six phases. From opening statements to appellate advocacy — each one designed to expose exactly where your advocacy breaks down.
Every simulation scores you across eight professional dimensions. Not vague feedback — a structured breakdown of exactly where you performed and where you didn't.
Practice on your own schedule, then bring what you learn to your next class, coaching session, or moot court rehearsal.
Openings, closings, direct, cross, objections, appellate advocacy. Drill the skill that's weakest or run a full simulation start to finish.
