The AI red pen
Graider is an AI test grader for teachers who photograph paper tests. Upload the test and your answer key, photograph the stack, and get marks against your rubric. Review every comment, toggle what students see, then hand work back as a PDF or an email.
Sunday evening, twenty-eight quizzes on the desk. You already know how you want them marked. This AI test grader is built for that pile, on the key you already trust.
Drop in the paper students sat and the answer key you already use. Graider pulls the questions and the answer bank, so you skip retyping the whole test.
Shoot each paper with your camera, or pull photos from your library. Confirm the roster match once. Then the lot can be marked together.
Scoring follows the key and rubric you uploaded. Partial credit, units, the way you always mark question 3: your standards stay the source of truth. You review and toggle feedback before anyone else sees it.
Share a marked PDF right away, or email results with each student's address already filled in. The stack leaves your desk the same night.

Graider is built for teachers who photograph a paper pile and mark against their own key. If you want that photo-and-own-key loop, this is the fit. Graider vs Gradescope walks through when a structured scan pipeline may suit a department better.
Chatbot paste means typing the work out first, then hoping the model follows your marking. Here you photograph the paper and grade it against the key you uploaded. The stack stays on your phone. The rubric stays yours.
