The engine
Two research-backed systems working together: KST maps every skill dependency so the system always knows what's next, and FSRS schedules each review shortly before a student is likely to forget.

A directed graph of skill prerequisites. The system knows exactly which skills a student is ready to learn — and which ones they're not ready for yet.
Free Spaced Repetition Scheduler calibrates each review interval to the individual. Items come back shortly before a student is likely to forget them.
Placement uses edge-calibrated assessment to find the level where a student is ready to learn. Adaptive features for Primary Advantage are targeted for May 2027.
The suite
Primary Advantage, Reading Advantage, and CodeCamp Advantage are live. Mastery Advantage runs in CodeCamp Advantage and is entering Primary Advantage through tagged content. Science, Math, Zhongwen, Storytime, and STEM Advantage are on our roadmap, with no dates.

For Thai private schools
Not a Western curriculum bolted onto a Thai schedule. Designed with teacher shortages, large classes, and limited devices as first principles, not afterthoughts.
Blended Learning means printed workbooks plus the digital app, with teacher training. Schools use the same books as families.

Comprehensive lesson plans and teacher guides reduce preparation time significantly
Printed workbooks give every student the same structure, in classes of any size
Blended learning model works with any device-to-student ratio
