For families who already have the videos
The lessons are there. Your child just isn't watching them.
A good video library is a wonderful thing to own and a hard thing to make a child use. Watching is passive, and a nine-year-old who is stuck has nobody to ask. Koydo is built the other way round: your child does something on every screen, and when they get stuck they can ask, in plain words, and get an answer pitched at their level.
The Koydo Advantage
What changes when learning is active
Somebody to ask, at 7am or 10pm
Every paid plan includes Koydo's tutor. It explains a concept a second and a third way, takes follow-up questions, and never sighs. That is the thing a recorded lesson structurally cannot do.
Learning your child chooses to open
Educational games, interactive simulations and hands-on science labs sit inside the curriculum, not beside it. Play is the delivery mechanism, not the reward for finishing the real work.
Practice that moves with them
Koydo watches what a learner actually gets right and re-pitches the next question accordingly. Nobody grinds through material they have already mastered, and nobody is quietly left behind.
One family account, up to six learners
Siblings at wildly different stages share one subscription and one Family Home, and each one gets their own progress, their own reading level, and their own pace.

Common Questions
Frequently Asked Questions
We already use free video lessons. Why add Koydo?
- Because they solve different halves of the problem. A video library answers 'where is the explanation'. Koydo answers 'my child watched it and still can't do it' — with a tutor to ask, practice that adapts to the answers, and a record of what actually stuck. Plenty of families keep both.
Is Koydo suitable for a self-directed teenager?
- Yes, and it stops nagging them. There is no streak to protect and no completion counter shaming them into logging in. A motivated teenager can go straight to college-level material; the tutor is there when a proof or a passage refuses to make sense.
What does my child actually do in a session?
- A short taught segment, then something to do with it — a game, a lab, a set of adaptive questions, a piece of writing. Sessions are built to end at a natural stopping point rather than to run as long as possible.
Does Koydo work in our home language?
- The platform runs in 50+ languages. Language study is included too, so a bilingual household can learn a subject in one language and check their understanding in the other.
