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.
What teachers are saying.
“Built by people who understand our classrooms and the local context.”
The bulk marking is particularly useful for handling large batches of scripts. By streamlining grading, it lets us redirect our time towards supporting student progress and closing learning gaps.
“It supports marking well while still letting teachers stay in control of the feedback.”
Bulk grading makes handling a full class set of scripts much more manageable. The tracking feature gives a clear picture of each student’s progress, and the end-of-semester summary makes it easier to identify areas to focus on.
“It writes the kind of feedback I’d write myself, just faster.”
Comments pick up on specific phrasing, ideas, and structural choices in each piece of writing. I rarely need to rewrite the AI’s suggestions, just refine them to match my own voice.
AI drafts it. You have the final say.
Zippy does the reading and drafts the feedback. Every word is yours to change, and nothing reaches a student without your say-so.
- Edit anything. Change, trim or rewrite any comment before a student ever sees it.
- Your standard, not a generic one. It grades to your rubric; override any mark, one tap to re-grade.
- Release when ready. Nothing is published until you approve it, and every approval is logged.
Grading that does more than score.
Per-skill diagnosis, batch marking, and reports that turn a whole class set into a teaching plan.
Your data stays yours
Every student, class, and piece of work is walled off per organisation.
Nothing is published without a teacher’s approval.
Every grade and every approval, logged.
