Who is TrialSim for?
TrialSim puts you in a realistic courtroom simulation — scored on the PRESENCE framework, the professional standard judges and supervising attorneys use to 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.

"The reps that make great trial attorneys have always required a clinic seat, a mentor, or a courtroom. Most advocates never get enough of them. TrialSim exists to change that."
Kris Charity, Esq. — Founder & CEO, former Assistant District Attorney

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.
