KAI Tutor is an AI foreign-language tutor that builds a personal study path for language exams such as TOEIC, TOEFL, IELTS and EIKEN. ■ Exams covered Lessons are pitched at the level each exam actually tests. • English: TOEIC, TOEFL, IELTS, EIKEN, PTE, Duolingo English Test, CELPIP, OPIc, CET-4/6, Cambridge English (KET / PET / FCE / CAE / CPE) • Japanese: JLPT • Chinese: HSK, TOCFL • Korean: TOPIK • Spanish: DELE, SIELE • French: DELF / DALF, TCF, TEF • German: Goethe-Zertifikat, TestDaF, telc • Italian: CILS, CELI, PLIDA • Portuguese: CELPE-Bras, CAPLE ■ Test Drive, no sign-up Tap Test Drive on the sign-in screen to try a lesson without an account. 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. After that, KAI Tutor Plus continues your learning (¥1,800 per month or ¥20,000 per year; local prices as shown in the App Store).
