What NodajiFi is
NodajiFi is the core learning app of the NodajiFi ecosystem: an AI-tutored, AR-capable platform for quizzes, exams, courses, and hands-on practice (experiment · practicum · practice). It begins with Korean-Wave culture and expands into diverse educational fields. Learning is rewarded with GEM, and completed learning can be anchored to tamper-evident, soulbound completion certificates.
1. Learn
Explore quizzes, courses, and Korean-Wave content. Every genuine act of learning earns GEM and keeps your daily streak.
2. Practice with your camera
In hands-on labs, place your phone on a simple stand: on-device AI reads your form (angle, path, timing, stability) and coaches you in real time. Raw practice video is analyzed on your device.
3. Prove it
Finish a course or lab and receive a completion certificate — soulbound, tamper-evident, never for sale.
4. Spend GEM
Unlock deeper courses and features inside the ecosystem. GEM is never money.
What GEM is. GEM is a reward point earned only through learning and genuine participation. It cannot be purchased with cash, cannot be exchanged or withdrawn for cash or crypto, and cannot be transferred between users ("three gates closed"). GEM has no cash value and is not a cryptocurrency, security, or investment.
