About Protu

Protu is a free AI-powered IELTS Writing correction service. Paste your Academic or General Training Task 1 or Task 2 essay, and in under thirty seconds you get an estimated band score plus sentence-level corrections aligned to the four official IELTS criteria: Task Achievement (Task 1) or Task Response (Task 2), Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy.

Who builds Protu

Protu is built and maintained by Peter Cha (peters.place), a solo founder from Seoul.

Why Protu exists

Traditional IELTS Writing tutoring costs $30 to $80 per essay. For learners preparing for immigration or study abroad — who need to submit dozens of practice essays to move from Band 6 to Band 7 — that cost is prohibitive. Protu delivers teacher-quality feedback at near-zero marginal cost so more people can reach the band score they need.
