MATHEMATICAL FLUENCY PLATFORM
Practice math.
Get fluent. Get unstuck.
When you're stuck, Kinora doesn't show you the answer — it teaches you exactly what you're missing, then puts you right back into practice.

The loop that builds fluency.
PRACTICE
Jump into problems matched to your level. Every problem starts with comprehension.
GET HONEST FEEDBACK
AI grades your process step by step. Your Proof Score (0–200) reflects how you think, not what you guess.
GET UNSTUCK
Stuck on the same concept twice? A targeted Micro-Lesson® appears — built from your specific mistake. It teaches exactly what you’re missing in under 60 seconds, then sends you right back into practice.
GET FLUENT
Track real mastery across 136 skills on your Honest Map. Share verified progress cards your parents and teachers can trust.
Other apps show you the answer.
Kinora teaches you why.
No generic video. No answer reveal. A targeted Micro-Lesson® built from your exact mistake. Then you practice again, with understanding.
Micro-Lesson® is a Kinora technology
STEP 2 - POWER RULE
2log(x) = ?
Same mistake. Twice.
Let's slow down.
MICRO-LESSON®
What the Coefficient Actually Does
You're multiplying the base by the coefficient. It actually becomes the exponent.
2·log(x) = log(x²)
↑ coefficient ↑ became exponent
GOT IT? LET'S CHECK.
3log(x) = ?
↳ Back to practice.
Bring your own question.
We'll teach you how to solve it.
Type any math problem. Kinora builds a step-by-step practice session around it — same process grading, same Micro-Lesson® when you're stuck. Or send it to your Teacher Vault instructor.
Kinora generates a step-by-step practice session. Same process. Same Micro-Lesson® if stuck.
Send to your Teacher Vault instructor. They respond with a custom practice problem.
See everything. Hide nothing.
One map. Every skill. Every gap. Nothing hidden.
Toggle AP overlays to see exactly what the exam tests — down to each FRQ type.
Not a gamified skill tree. An honest prerequisite graph powered by the same curriculum structure used in AP exam design.
We grade how you think.
A 200-point fluency rating built from process quality, skill breadth, consistency, and depth. It cannot be gamed.
Developed by the teacher who
grades the AP exam.
Maitri is an AP Teacher and AP Reader — she scores the national AP Calculus exam for the College Board. She designed Kinora's curriculum, wrote the problem bank, and defined what “process” means at every difficulty level.
Designed for the student who's capable but not yet fluent.
Every AI-generated problem goes through teacher review. This is not ed-tech built by engineers guessing at pedagogy. This is a teacher's tool, engineered to scale.
