## What is KAI Tutor?

KAI Tutor is an AI tutor that builds a personal study path for language exams such as TOEIC.

■ Diagnose first, then plan
A placement test measures listening, reading, grammar, vocabulary, writing and speaking on the CEFR scale. Tell it your target score and the time you have, and it writes a phased, week-by-week plan. You can keep adjusting the plan in chat after approving it.

■ 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?" Keep asking until it clicks. The mistake notebook keeps the question, the answer, the why and the whole conversation, with one more practice question on tap.

■ 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 ¥19,200 per year; local prices as shown in the App Store).
