Generate Exam-Quality Questions at Scale

Define your taxonomy (knowledge areas, subtopics, question counts) and let a multi-model AI pipeline generate, validate, and deliver exam-ready content.
Every question is stress-tested before delivery. Competing AI systems generate, challenge, and judge each item. Only validated questions survive.

Generated by one model, challenged by another, judged by a third. Only validated items survive.
Domain Calibration
Engineering, medical, CS, sciences, with style presets and difficulty calibration per domain.
Variant Generation
Surviving questions spawn variants with the same concept in a different context, so your bank grows.
Credit-Based Pricing
Pay for what you generate. No subscription. Credits work across all PassExams services.
