Rehearse your US visa interview with an AI consular officer
Speak naturally to an AI officer that asks follow-ups, challenges weak answers and throws in trick questions, mirroring a real consulate exchange without any typing.
Select your visa type — F-1, B1/B2, H1B, K-1, J-1 and more, eight categories in total — and the session draws on real consulate question patterns for that route.
Each session ends with an Approved or Denied verdict, a confidence score and three specific corrections, so you know exactly what to rehearse next.
A free readiness score tool, a DS-160 consistency checker, a documents checklist, a bank-balance calculator and a 100+ question bank are available alongside the interview simulator.

Voice-driven AI role-play that builds, measures and proves officer readiness
Upload general orders, SOPs and lesson plans once, and every scenario draws its content from your own policy language.
Describe the call officers should practice and Kaiden drafts the scenario, the AI role-player and the objectives from your policy.
An AI role-player plays the caller, witness or suspect, with named voices labelled by gender, accent and age, and reacts live to what the officer says.
Every attempt returns met/unmet objective results with the quoted line, a four-part written review, and coaching on empathy, tone, pacing and composure.
