AI Essay Grader

An AI essay grader reads your written answer and scores it against a marking rubric — like a teacher grading an exam. Mindko turns your own study material into open-ended questions, then grades the full answers you write, with a score and specific feedback on each one.

Mindko writes exam-style questions from your material, each with its own rubric and a model answer. You write a full response in your own words, and the AI examiner marks it against that rubric — awarding points for what you covered and flagging what you missed. Your final score is the marks awarded out of the total, and every question comes with written feedback.

Yes — create a free account and get your first writing graded without paying. A Mindko Pro subscription unlocks unlimited graded tests and the rest of the Study Set.

Anything you'd answer in an exam — short-answer responses, paragraph explanations and full essay-style answers. Add a PDF, lecture slides, a textbook chapter or your own notes, and Mindko builds the questions and rubric from that material, so the grading is grounded in what you're actually studying.

No — this is a grader, not a writer. Mindko's essay grader marks the answer you write and shows you exactly how to improve it. If you want help drafting instead, that's our separate free AI essay writer; the grader is for getting honest feedback on your own work.

Instead of a generic chat reply, Mindko grades your writing against a real rubric built from your own material — with a score, point-by-point feedback and a model answer for every question. And it's part of your Study Set: the same upload also makes your notes, flashcards, quizzes, mind map and study podcast.
