One sentence a day, typed from what you hear — in 11 languages
A new everyday sentence, read by a natural voice, is delivered each day in the language you are studying. Replay it as often as you like before typing.
Write the sentence you heard. The checker is tolerant of accents, kana and spacing where the ear genuinely cannot tell the difference.
After each attempt you see exactly which words you caught and which you missed, plus the correct sentence and a translation into your own language.
English, Spanish, French, Japanese, German, Korean, Chinese, Italian, Portuguese, Russian and Dutch, each with its own daily challenges and streak you can switch between freely.
