Protu

Protu is an AI IELTS Writing checker for Academic and General Training, Task 1 and Task 2. Paste or write your essay and get an estimated band score with criterion-by-criterion feedback (Task Response, Coherence & Cohesion, Lexical Resource, Grammatical Range & Accuracy). Every mistake is marked in place, and clicking it explains why it's wrong — in English, Korean, Chinese, Arabic, Spanish, Japanese or Nepali. The core loop is rewriting: Protu keeps your previous attempt beside you so you can rewrite the same essay with the feedback and see whether your band moves. One essay check per day is free with no card, and essays stay private even on the free plan. Pro ($4.99/mo) and Max ($9.99/mo) add more checks.
