#1The AI teaches; deterministic code decides
Verified against the codebase
Sathi never decides whether a student advances. Mastery requires covering each concept’s named requirements, then passing a check built from fresh, objectively graded questions the student has not seen during teaching. Wrong answers are traced to specific mapped misconceptions and re-taught from prerequisites; unresolved gaps are parked and revisited, never silently skipped.
#2Human-authored curriculum spine
Reproducible from the content library
Every course is a prerequisite-aware concept map authored by humans before any AI touches it: 1,000+ concepts, 4,600+ named coverage requirements, over 1,900 distinct student misconceptions tagged 2,600+ times (floors as of 2026-08-11; the library grows as courses are authored). AI delivers the teaching; it does not invent the map.
#3One arc, personalized road, fixed bar
Verified against the codebase
Every session: recap → engagement → teaching → a deeper challenge → the student produces something → clean close, no infinite feed. Personalization changes the road — opening, pacing, what depth looks like, how stuck-ness is handled, tone, content voice. The mastery standard never varies by student: expectations can rise for students seeking more depth, never fall.
#4Built to climb Bloom’s taxonomy
Verified against the codebase
Sessions ascend from understanding through analysis to creation; mastery checks close concepts at the upper tiers; the token economy prices the climb — a basic correct answer earns 5 tokens, explained reasoning 15, defended reasoning 30, cross-subject connection 50. Creation earns; consumption costs.
#5Archetypes personalize voice, never gate progression
Verified against the codebase
Eight archetypes (Builder, Questioner, Storyteller, Pattern Seeker, Explorer, Systematizer, Perfectionist, Intuitive) shape how Sathi speaks and frames challenges. No matched-instruction outcome claim is made. Progression is gated for every student on the same objectively graded mastery checks.
#6Birth details, disclosed
Verified against the codebase
Date of birth is collected for age verification and parental consent. Birth time and place, together with the student’s own preferences and a short warmup, seed an initial teaching-style estimate inspired by Jyotish, the traditional Indian framework in JyoLing’s name. Profile guidance is offered as a starting point to try — never a limit or an outcome prediction. No forecasts or fortune-telling; birth details are never shared or sold.
#7Privacy by architecture
Verified against the codebase
The AI layer receives the course, the concept, and the question — no name, email, age, location, or birth data. COPPA and FERPA aligned; no data selling, no advertising.
#8The consumer-to-creator thesis
Design commitment · evidence-hedged
JyoLing’s deepest design commitment links how a student engages to who they become. The evidence for creation is strong: learning by teaching — explaining, defending reasoning, producing original work — is among the best-supported effects in learning science, and building demonstrated competence is a well-established foundation of agency and motivation.
The evidence on passive consumption is directional but contested: many studies associate passive scrolling with poorer adolescent wellbeing, though large reviews find the effects inconsistent and person-specific — so JyoLing does not claim consumption causes harm or that creation treats anything.
What JyoLing claims is architectural: every mechanic prices consumption and rewards creation — sessions end in production, explanations earn more than answers, and there is no infinite feed — because a student who practices creating builds capability that passive consumption never exercises. The claim is educational, not medical.
