Speak Japanese. Keep what you learn.

Talk out loud with Yui, an AI voice tutor, for up to ten minutes, then get honest feedback, a level estimate, and the words you needed as spaced-repetition cards.

Uses your microphone. Speak at your own pace; English is allowed when you are stuck.

Your cards

Your first conversation fills this deck with the words you actually needed.

Yui is an AI tutor, with a voice by ElevenLabs. Conversations are transcribed to build your review and cards. CEFR levels shown are estimates for practice, not certificates. More languages are on the way.
