Available in English, Japanese, Chinese, Korean, Spanish, French, German, Italian and Portuguese, with more languages on the way. ■ Diagnose first, then plan A placement test measures listening, reading, grammar, vocabulary, writing and speaking on the CEFR scale. Tell it your goal and it writes a phased, week-by-week plan. Details like how much time you have can be added in chat later, and the plan adjusts. ■ Every lesson sits just above your level Grammar, vocabulary, reading, listening and speaking, one block at a time. Accuracy and time spent shape the difficulty and length of the next lesson. Words and grammar points due for review are woven into lessons before you forget them. ■ Miss a question, get it explained in your language Explanations come in your language. Still unsure? Ask the tutor right there — "why an, not the?", "why would, if it's the future?" — and keep asking until it clicks. The mistake notebook keeps the question, the answer, the why and the whole conversation, with similar questions to practice as often as you like. ■ Listening and speaking Listening uses natural multi-speaker dialogues. Speaking records you reading aloud and scores pronunciation and intonation (recordings are scored, not stored). ■ Progress you can see A six-skill radar, phase completion, study days, streaks and badges. Parents get a weekly report and a PIN-protected guardian space. ■ Price Everything is free for the first 30 days.
