Grade a whole class
in minutes.
Upload a class set, typed or handwritten. Zippy reads every script against your rubric and drafts skills-specific feedback. You approve every word before a student sees it.
See the feedback for yourself.
Paste one piece of writing and see the feedback a student actually gets back.
Calibrated to MOE / PSLE writing. Real feedback from the live grader.
The feedback you’d write yourself, if you had the hours.
Specific, kind, and tied to your rubric. Zippy gives skills-specific feedback that tells you where and what to fix, on every single piece.
The rain had just stopped when I noticed the leather wallet wedged beneath the bench, its corners frayed and soft with age. For a long moment I just stared at it, while the evening crowd flow past me, umbrellas dripping, nobody slowing to look down.Tense slip: flow → flowed. It creeps in when your sentences run long, so reread those.
I picked it up and felt the weight of the coins shifting inside. A small, stubborn part of me, the part that had been saving for a new football for weeks, whispered that nobody would ever know.
My fingers tightened around the strap of my bag.Lovely, you’re showing the nerves instead of naming them. Push once more: what was the worst thought crossing your mind? I knew exactly what the right thing was. I just hadn’t expected it to feel so heavy, standing there with a stranger’s whole evening in my hands.
So I carried it to the guard room at the void deck, past the snack shop I usually stopped at, and slid it across the counter before I could change my mind.
When the owner finally arrived, breathless and grateful, he pressed a folded note into my hand. I shook my head and walked off before he could insist, my pockets empty but somehow lighter.Outstanding closing image, “empty but lighter” earns the whole story. Your strongest line.
You build a vivid, believable scene and your closing image lands the theme beautifully. To lift it further, hold the moment of temptation a beat longer before you resolve it, and watch tense agreement in your longer sentences.
Zippy marks to your rubric.
Your criteria, your bands, your descriptors, the same ones your department already moderates against. Zippy scores against that rubric and shows you which descriptor it matched for every criterion, so a mark from Zippy means what a mark from you means.
The scoring instrument
Criteria down the side, levels across the top, and a descriptor in every cell. Marks, bands, or a range of marks per band.
The taxonomy underneath
Traits and the skills inside them, each with a descriptor per band. This is what turns a mark into per-skill mastery.
What you actually attach
One or more rubrics, plus the feedback settings: comment, next steps and annotations, each on or off. Save it once, reuse it every term.
Criteria by levels, with a descriptor in every cell. Edit any of it.
