About Pencraft English: Writing AI
AI-powered English essay learning, all in one app. The ultimate study tool for university entrance exams, Eiken, TOEFL, and IELTS writing sections.
■ Three Learning Modes
【Composition】Japanese → English Translation
Just enter Japanese text, and the AI first paraphrases it into "translation-friendly Japanese," then translates it into English with detailed vocabulary, grammar, and expression explanations for each sentence. Understanding "why it's translated this way" helps you write on your own next time.
【Correction】Instant Feedback on Your Writing
The AI corrects your English writing sentence by sentence — not just pointing out errors, but explaining the correct expressions and reasoning. Build vocabulary and grammar knowledge simultaneously.
【Scoring】Real Exam-Format Scoring
