Build the reps that used to require a clinic

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.

Every phase of trial, simulated

Step into realistic courtroom simulations across all six phases. From voir dire to closing arguments — each one designed to expose exactly where your advocacy breaks down.

Scored like a real advocate

Every simulation scores you across eight professional dimensions. Not vague feedback — a structured breakdown of exactly where you performed and where you didn't.

On your schedule, not theirs

No clinic seat. No moot court waitlist. No scheduling around anyone else. Train at midnight before trial if you need to.

Six modules, one complete skillset

Openings, closings, direct, cross, objections, voir dire. Drill the skill that's weakest or run a full simulation start to finish.

Built by a trial attorney. Trusted by advocates in 45+ countries.

More deliberate practice in one week than most advocates get in a year

Run realistic simulations across every phase of trial — openings, direct, cross, objections, closings, voir dire.

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.

Your Questions Answered

Real questions from real advocates using TrialSim.

1. How does TrialSim work?
2. Who is TrialSim built for?
3. What is PRESENCE and why does it matter?
4. Is there a free trial?
5. Does TrialSim work for legal systems outside the U.S.?

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.

6. How is this different from practicing with a colleague or in moot court?

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.
