Kung Fu Quiz is an enterprise-scale EdTech gamification engine designed to solve the passive video learning crisis in modern classrooms. Built on Next.js, Jotai, and GSAP with YouTube IFrame API synchronization, the platform allows teachers (Sifus) to embed timestamped assessments into educational videos without streaming latency. Students join live interactive sessions instantly via 6-character Dojo codes at kungfuquiz.net without mandatory account registration, eliminating classroom onboarding friction. Powered by the proprietary sensAI natural language processing engine, educators can generate complete curriculum-aligned quizzes from video transcripts in under 30 seconds across six cognitive formats: Single Choice, Multi-Choice, Open Text (with fuzzy typo tolerance), Chronological Ordering, Pair Matching, and Word Guessing. The platform includes live classroom telemetry, individual student diagnostic breakdowns, and customizable game, assessment, and homework modes.
Modern educators struggle with passive video consumption where student attention wanes after 3–5 minutes. Legacy quiz tools like Kahoot enforce strict 10–20 participant paywalls on free tiers, focus on speed rather than retention, and cannot pause or synchronize natively with YouTube video streams.
Engineered a real-time video quiz synchronization layer that intercepts YouTube playback timestamps, overlays 6 distinct cognitive quiz mechanics without video buffer delays, allows instant zero-account student participation via 6-character Dojo codes, and automates quiz creation via the sensAI transcript-analysis NLP engine.
Scaled to tens of thousands of active classroom sessions across Asia and international schools with 94%+ completion rates. Reduced teacher quiz creation time from 45 minutes to under 30 seconds with zero participant capacity caps.
