■ AI ENGLISH TEACHER COACHING
- Grammar, spelling, tense, article and preposition fixes — each with a clear explanation in your own language
- Natural, native-like expression suggestions so you sound more fluent
- A writing score (0–100) and a warm, personal note of encouragement

■ "THIS IS WHAT I MEANT" — INTENT COACHING
Can't find the right English words? Jot down what you wanted to say in your own language.
