Built on the same adaptive engine that powers our certification platform — not a worksheet generator, not a video library, not another LMS.
Skip what you already know
Traditional study can burn a lot of time on material a student has already mastered. The engine maps proficiency at the concept level and only surfaces what actually moves the needle — see our methodology for how we measure that.
Diagnose why, not just what
A wrong answer on a quadratic word problem traces back to fraction operations, or rate-of-change, or variable substitution — whichever prerequisite actually broke. Then it prescribes that, not more quadratics.
Standards-aligned out of the box
Common Core, NGSS, TEKS, plus state-specific frameworks. Teachers see standards coverage per assignment. Parents see standards coverage per student.
No data-mining, no ads
Zero tracking cookies. Zero third-party analytics. We don't sell student data and there's nothing to sell anyway.
Free through 8th grade
Kindergarten through 8th is free — the whole engine, not a stripped demo. High school (9–12) is a paid subscription, because that is where the workload, the stakes and the cost of getting it wrong all jump. Schools that want SSO + roster-sync + LMS integration can buy a Schools plan at any grade band.
Works on whatever device the kid has
Web-first, mobile-friendly, accessible. Chromebooks, iPads, Android tablets, family laptops, phones in study hall — all the same experience.
