Launch your own branded math app — in days, not months.
Kimsa is a calculator-free math-practice & assessment engine you put your brand on. Seven math tracks, audited-correct, runs offline. You ship; we power the math.
A proven engine, wearing your brand
Everything a math-practice product needs — the hard, verified part — ready to skin as your own.
Ship in days, not quarters
No dev project: send a brand kit — name, logo, colors, subjects — and the finished engine reskins at runtime, ready to launch.
Seven math tracks
Algebra I & II, Geometry, and SAT / SSAT / ISEE / HSPT math — calculator-free, exact-answer — plus verbal & reading for the entrance exams.
Provably correct
Every generator is machine-audited. Each wrong option is a named, diagnosed error.
Unlimited fresh sets
Every practice set is generated new — nothing to exhaust, nothing to memorize. Students always get problems they haven't seen, even offline.
Safe for students
No personal data collected. Progress never lost. Privacy-first by design.
Teachers see everything
A read-only dashboard of each student's readiness and recurring mistakes — plus a diagnostic that builds every student a personalized study plan.
Seven math tracks, calculator-free
Exact answers — clean integers, fractions, and radicals — with distractors that pinpoint the mistake.
Algebra I
Linear & quadratic equations, factoring, functions, systems, word problems.
Algebra II / Precalculus
Complex numbers, polynomials, rationals, logs, sequences, conics, trig.
Geometry
Angles, triangles, circles, coordinate geometry, area & volume, transformations.

HSPT*
The real two-section math structure (Quantitative Skills + Mathematics) — plus Verbal Skills and Reading.
Entrance-exam verbal & reading run on frozen, hand-verified corpora — a 1,209-word vocabulary bank with roots, analogies, sentence completions, and 120 original reading passages.

Kimsa began as one parent's build for one student — a daughter facing a high-stakes math placement retake, with no tool that would tell her why an answer was wrong. So we built it: unlimited calculator-free problems, exact grading, and a researched catalog of named mistakes. Practice test by practice test her score climbed, and she walked out of the retake with her best score yet. The engine kept growing — seven tracks, entrance exams, verbal & reading — and now powers the Kimsa app and the white-label programs on this page.
