One submission. Every answer a teacher needs.
A student turns in an essay once — Checkmark checks it against the web, screens for AI, reconstructs how it was written, and drafts rubric-based grades. Here is everything that happens, and how each piece works.
A real Checkmark report — originality tiles, autograder scores, the highlighted essay, and evidence cards, all on one page. Explore the interactive example.
