Teachers struggle to detect AI-generated or plagiarized student essays because unfamiliar writing styles can be mistaken for cheating, and prewriting doesn't always match final submissions.

Existing plagiarism checkers cannot reliably distinguish between AI-generated content and authentic student writing when the student's usual writing style is unknown or inconsistent.
