Realistic witness examination training, scored.
Sharpen your skills and build confidence, before it counts.
Examine a live AI witness out loud — cooperative, neutral, or uncooperative — then get your performance scored against a rubric, with exactly what to fix.

Why SimDuo?
Practice before client outcomes, and your reputation, are on the line.
All litigators know roleplay scenarios are an important part of development and preparation. Many skip them anyway.
Why? Traditional roleplay exercises require coordination with others and can be very expensive. Trial skills training workshops cost between $3,000-$5,000 before travel. They also operate around a fixed schedule and location, rather than your schedule.
Like many things, trial skills are perishable. Consistent practice over time is the key. Just like running 50 miles this week does not prepare you for a race in 9 months, cramming trial skills this week does not prepare you to perform months from now.
SimDuo provides realistic, simulated training 24/7 with no required coordination for a fraction of the cost of traditional training methods.
Clients don’t pay attorneys to practice on real matters. Clients expect attorneys to be training and prepared when it matters. What is the value of your reputation as an attorney or firm?
SimDuo’s training platform, rubrics, and scenarios were designed for attorneys by an attorney who has conducted hundreds of witness examinations.
