You're teaching, marking, and buying ink.
Worksheets are cheap and endlessly available, and every one of them still needs an adult to explain it, mark it, and remember what it showed. Koydo does those three jobs: it teaches the lesson, marks the practice as it happens, and keeps the record of what your child understood — which is the part that no printable can carry.
The three jobs a worksheet leaves you holding
🧑🏫It teaches, not just tests
Each topic is taught first — narrated, illustrated, with something to try — so the practice lands on an idea your child has actually met.
✅Marking happens instantly
Answers are checked as they are given, with a warm nudge and a second explanation for the wrong ones. Nobody spends Sunday evening with a red pen.
🗂️The record keeps itself
What was covered, what stuck, what needs another pass — captured per child as it happens, instead of living in a pile on the kitchen table.
🤖Someone to ask mid-question
Koydo's tutor is there at the moment your child is stuck, not at the moment you next sit down with them. Included on every paid plan.

Frequently Asked Questions
- Sometimes a pencil is the right tool, and worksheets are easy to come by. What Koydo replaces is the part after printing — the teaching, the marking and the memory of what it showed.
- No. You can go straight to a subject and topic yourself. The recommendation engine is there for the weeks when you would rather not decide.
- It helps that sessions are short and end at a natural stopping point, with no streak or quota pushing for more. Audio lessons and songs also work away from a screen entirely.
- One subscription covers every core subject for up to 6 profiles, with the teaching and marking included — compare it against the pricing page rather than against a per-sheet cost.
