Specific, urgent, and still unsolved — the kind of pain that converts

One-Liner

Language teachers photograph or upload student writing assignments; AI corrects each submission (grammar, vocabulary, spelling with CEFR-appropriate explanations in the student's native language) and generates a teacher-reviewable correction report per student — reducing grading time from 10 minutes to 2 minutes per student.

Kill Reason

Language teachers at private schools and tutoring centers can already achieve the same grammar corrections with standard LLM prompts at no cost — Duolingo, Google Translate, and general AI tools provide CEFR-aware corrections, and there is no proprietary dataset or network effect that prevents any competitor from building an identical workflow in a matter of days.
