Your Questions Answered

Everything you need to know about 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.
