A high school student studying calmly at a sunlit desk at home.

Every AP course.
One tutor that adapts.

Adaptive practice for 17 AP courses, with an explanation for every answer. Kalyta finds what you have not mastered yet and keeps working on it until you have.

$12.99/month after your free days. One subscription covers every course in the app, so you can study more than one at no extra cost.

It finds the gap, then closes it.

Adaptive practice

Every answer moves the estimate of what you know. The next question is chosen from what that estimate says you have not mastered.

An explanation for every answer

Not just which option was right. Why the one you picked was wrong, and what to do differently next time.

Full-length rehearsals

Sit the real thing under real timing, then review every question with the reasoning beside it.

A student smiling as a concept clicks while studying at a desk.

The best part is when it clicks.

Kalyta is built for that moment. You understand the idea, not just the answer, so it stays with you long after the session ends. That is the difference between learning something and cramming it.

A student learning at their own pace at a sunlit kitchen table.

Fits your life, not the other way around.

On the bus, at the kitchen table, the night before, or all year long. Kalyta works whether you have an exam date or you just want to get better at the subject. You set the pace, and it keeps up.

17 AP courses

Every AP course in the app is built the same way: lessons, an AI tutor you can ask anything, adaptive practice with a worked explanation behind every answer, point-by-point grading of your written free-response answers, and full-length exam rehearsals with a predicted 1 to 5 score.
