For families doing daily practice
Practice is easy to find. Teaching is the scarce part.
A question your child gets wrong is only useful if something then teaches them the thing they got wrong. Koydo puts the explaining first — a tutor that talks the concept through in their words — and lets the practice follow, adapting to what they now understand.

A tutor, not just an answer key
Koydo's tutor explains a concept a second and a third way, takes follow-up questions and works an example alongside your child. It is included on every paid plan.
Adaptive, without the quota
Difficulty follows the learner rather than a target count. There is no daily number to hit and no score that punishes the wrong answers, which are the most useful thing a learner produces.
Every core subject, one price
Maths and language arts sit next to science, history, coding, art and music — so a strong week in one subject has somewhere to go next.
Games and labs carry the practice
Educational games across every subject and hands-on science and engineering labs, so repetition arrives as play rather than as a worksheet on a screen.
One family account, up to 6 learner profiles
Siblings at different stages share a single subscription and a single parent view, each with their own level and their own progress.
Languages and test prep included
50+ study languages with speaking practice, plus SAT, PSAT and AP preparation, without a second subscription.

Frequently asked questions
How much practice material is there?
Over a million practice questions across the curriculum, selected adaptively rather than served in a fixed order — enough that a child working a weak area does not start recognising items by sight.
My child freezes when they get things wrong. Is Koydo harsh?
No. A wrong answer produces a warm nudge and another explanation, never a red wall, and there is no streak or score to lose. Children who are afraid of being wrong stop guessing, and a child who stops guessing stops learning.
Can I see which topics are weak?
Yes — the parent view shows each child's subjects, recent sessions and where the ground is soft, without turning it into a leaderboard the child feels judged by.
Is this useful for a child who is ahead rather than behind?
Very. The sequence runs through to college-level material, so a learner who has mastered their year's work simply keeps going instead of repeating it in a different colour.
