Sound familiar?
Matching a word to a picture gets a learner to intermediate and then quietly stops paying off, because choosing the right tile is a different skill from building a sentence yourself.
A cross tells you the answer was wrong. Koydo explains what went wrong, and where it can, which habit carried over from your first language is causing it.
Koydo's supported speaking activities listen and give sound-level practice cues. The feedback is automated, may be imperfect, and is a practice aid rather than a fluency or accent certification.

Hold the /te/ stress longer so the rhythm lands in the right place.
Keep the middle /sin/ crisp instead of flattening it into one blur.
Repeat once slowly, then once at full speed to lock in the correction.
Why this converts
Learners do not just get a score. They see exactly which sound broke down, what to change, and how quickly the next attempt improves.
Why learners switch

Koydo uses proficiency labels to organize supported language activities. Coverage varies by language and activity.

Supported speaking activities can provide sound-level practice cues. Feedback is a practice aid, not a fluency or accent-outcome promise.

Koydo includes selected subject-based activities alongside language practice. Current availability varies by language and level.

Common questions
Three things: the next step is defined against a CEFR level rather than guessed, wrong answers come with an explanation of what went wrong, and supported speaking activities listen to you. Koydo does not guarantee fluency or a proficiency outcome.
Content and Language Integrated Learning combines subject-based activities with language practice. Koydo offers selected CLIL-style activities; availability varies by language and level.
Supported Koydo speaking activities can compare sounds with a reference and provide practice cues. The feedback is automated, may be imperfect, and does not certify pronunciation or fluency.
The placement activity shows its current access requirements before you begin. Results are Koydo practice estimates, not official CEFR certification.
Over fifty, including Spanish, French, German, Mandarin, Arabic, Japanese, Korean, Portuguese, Italian and Russian. The interface runs in 50+ languages too, so you can navigate in the language you speak at home while studying another.
