The hard part of a Sunday stack is rarely deciding what a right answer looks like. You already have a key. You already know how you give partial credit. You already know which units matter on question 3.
What eats the evening is applying that judgment thirty times by hand.
Graider is AI grading against your own rubric. Upload your test and answer key, photograph the papers, get marks against that key, then hand work back as a PDF or email with feedback you still control. Rubric-based AI paper grading keeps your partial credit, units, and marking language as the source of truth.
Your key. Their papers. Marked tonight. You keep the pen.
Keeping the pen means your standards stay the source of truth.
Marks and feedback come from the answer key and rubric you provide. You confirm the roster match before the lot runs. You review after. You toggle feedback on or off before anything reaches students. Nothing goes out until you release it.
That is the loop teachers already trust: your judgment first, the stack second. Graider moves the volume. You still decide how the work should be marked.
Every classroom has its own marking language. Some teachers want the exact method shown. Others accept an equivalent path if the reasoning is clear. Units, significant figures, working that must be visible: those are your calls.
When marks come from your key and rubric, that language stays intact. You are not rebuilding the paper in a new platform. You bring the test you already wrote and the standards you already use.
That matters for trust. Students get feedback that sounds like you. You can stand behind the mark because it came from the same key you would have used at the kitchen table.
Upload the paper and your key. Graider pulls the questions and the answer bank automatically, so you are not retyping the whole thing by hand.
Shoot the papers with your camera, or pull photos from your library. Graider matches pages to students on your roster. You confirm once. Then it grades the lot against your key and rubric. How to grade papers faster with AI photos.
When marking finishes, look over what you need to. Toggle feedback on or off. Share a marked PDF, or email results with each student's address already filled in.
You stay in the release seat the whole time.
When every evening is pure volume, pattern-finding dies first. You finish tired. You remember a few rough papers. The class-level story stays fuzzy.
Faster marking against your own rubric changes that. Wrong units on Q3 show up across the set. A blank section shows up as a pattern, not a one-off. You can see where the class is stuck while you still have energy left to reteach.
That is spotting struggles in honest terms: the pile gets marked on your standards, so you see patterns across the marked work sooner. It frees attention for the teaching only you can do.
Graider is for teachers who still collect paper (or photograph it) and lose evenings to the desk pile. If you already have a test, an answer key, and a sense of how you mark, you do not need a new philosophy of assessment. You need the stack cleared without giving up the pen.
Sunday evening, twenty-eight papers. The goal is simple: done on your standards, before the night is gone.
Flow: upload test and key, then photo papers, then confirm matching, then grade, then hand back.
