DoorZero simulates the high-stakes interactions professionals face — so you walk into the real thing already ready. Now live for board exams.
Counterpart
Responds and reacts in real time — in character, every time.
You
Practice by voice or text — as many times as it takes.
Session score
88/100
Scored on an objective standard
So we let you live it — with a counterpart that behaves like a person, and feedback that behaves like a judge.
Speak with realistic, AI-driven people who respond, react, and stay in character — practice, not a quiz.
Live timing, one attempt, no do-overs. We recreate the stakes, because composure under pressure is the skill.
Every session is scored against an objective rubric — specific, grounded, and clear about what to fix next.
Our first release puts DoorZero inside the redesigned NBCE Part IV boards — a full, timed clinical simulation. The whole experience, pricing, and sign-up live on the simulator itself.
Board exams are the first proving ground. The same engine can simulate any interaction people have to get right — across new fields, professions, and high-stakes moments.
