Language learners, pronunciation practicers, and families building speaking confidence.

AI by design
AI is part of how Koydo teaches here, adapts to your child, and shows you their progress.
Koydo AI helps explain, rephrase, ask better follow-ups, and keep learners moving without replacing effort or teacher judgment.
Every bit of practice, every mistake, and every creative moment helps Koydo tune the next lesson to your child — and keeps your parent or teacher summary clear and honest.
Our promise stays simple: age-aware help, strong safety, progress you can see, and room for a real person to step in when it matters most.
Try it for real
What you can play and explore right now.
Uses the browser's on-device speech recognition where available; says so plainly where it is not.
Clarity, rhythm, and meaning are scored against the target phrase you see.
On Koydo's apps the same scoring runs on-device (Apple Speech / Android SpeechRecognizer).
