TrialSim gives law schools, legal teams, and individual advocates realistic trial and appellate simulations with structured PRESENCE feedback—on demand.
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.
No clinic seat. No moot court waitlist. No scheduling around anyone else. Train at midnight before trial if you need to.
Openings, closings, direct, cross, objections, appellate advocacy. Drill the skill that's weakest or run a full simulation start to finish.

Get scored on PRESENCE: the 8-component framework that measures what actual advocates are evaluated on.
The reps used to require a clinic, a coach, or a courtroom. Now you can log them on your own schedule.
Courtroom excellence has always depended on access—to clinics, mentors, and opportunities. TrialSim gives every advocate a place to practice repeatedly, receive structured feedback, and improve before the stakes are real.

The Art of Trying to Be Great (And How TrialSim Fits In)Real questions from real advocates using TrialSim.
Yes. The core advocacy skills TrialSim trains — structuring arguments, examining witnesses, handling objections, reading a room — transfer across legal systems. Users from India, Brazil, the UK, Colombia, and elsewhere train regularly on the platform. Scenario sets specific to non-U.S. legal frameworks, including civil law systems, are in active development.
Moot court and colleague feedback are valuable — but they're scarce, hard to schedule, and inconsistent. TrialSim gives you unlimited reps on demand, scored the same way every time. You can run the same cross-examination ten times in a row until it's sharp. You can practice at midnight before a trial. And you get structured PRESENCE scoring instead of subjective impressions. It doesn't replace live practice. It makes live practice count more.
