Why we built Zippy

Nobody became a teacher to spend Sunday marking.

But that is where the hours go. And the student who needed something different this week has to wait until there is time, which there never is.

Marking used to look like this.
The challenge

Differentiation asks the impossible

Every child needs teaching pitched where they actually are. Doing that properly, for a full class, every week, was never humanly possible, so everyone gets the same worksheet.

The pile never clears

A whole class set on a Sunday night. By the time it is handed back, the class has already moved on.

The teaching comes last

Planning the lesson. Sitting with the student who is stuck. The reason you took the job is whatever time is left once the marking is done.

Zippy takes the hours out of marking, not the care. Every student gets feedback you would be proud to sign, and you get the time back for teaching.


Grade · Understand · Personalise

Mark the class once, and every student gets their own next step.

Zippy reads each piece against your rubric, learns what that student needs next, and drafts the personalised practice to get them there. You approve it and assign it. A whole class personalised, in the time it used to take to mark one group.

1
Bulk grading a whole class against your rubric, with live progress

Grade the class

Upload a class set, typed or handwritten. Every script marked against your rubric in minutes.

2
Per-skill assessment showing which skills a student is strong or weak on

Identify each student's weak areas

Zippy pinpoints the exact skills each student is weak on, and the ones they have nailed, straight from the work they just handed in.

3
A drafted lesson aimed at specific skills, ready to assign

Create targeted practice

In a click, draft a lesson or practice built for that student's weak skills. You assign it, and Zippy re-checks those skills on their next piece.

Personalised to each student's needs · you approve each step

Rachel's learning, one practice at a time.

Rachel hands in a narrative practice. Watch Zippy turn that single piece into a plan built for her, and repeat it for every other name on your register.

Punctuating speech
Practice · assigned to Rachel Lim
Punctuating dialogue
Learn first
Punctuating speech follows three rules:
Speech marks wrap the exact words spoken.
The comma or full stop sits inside the closing mark.
Every new speaker starts a new line.
“I can’t take it,” I said, shaking my head.
The guard smiled. “Then you’ve already earned it.”
Now you try · Question 1
Add the missing speech marks and punctuation to this line.
I can’t take it I said, shaking my head
Question 2
Rewrite the conversation in paragraph three so each new speaker starts a new line.
Assigned · due Friday · auto-graded and re-checked against Punctuating dialogue.

Personalised learning

Every student learns and progresses at their own pace.

Zippy keeps track of what each student has mastered and what they are still missing, so the work they get next is pitched where they actually are. They see it too: their skills, their progress, their next task.

Analytics & progress

Keep track of every student's progress.

Every piece you mark updates the same place: each student, each class, each skill. The gradebook stays current on its own, so you can see who needs you next.

Zippy AI

An assistant for you. A teacher for them.

Two kinds of help, both tied to your classroom. One works beside you across grading, creating and progress. One sits beside a student's work and nudges them forward without handing over the answer.

One assistant across grading, creating and progress

It marks a class set against your rubric, drafts the lesson, worksheet, quiz or rubric you ask for, edits what you already have, and keeps every student's progress current as you go.

An AI teacher that never gives the answer

Each class can have its own, and you configure it: its name, its voice and how it talks to your students. It understands the context the student is working on, replies with a hint or a question, and never marks.

Real teachers, real classrooms

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.

MC
Ms ChongPrimary school English teacher

“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.

MK
Mdm KohPrimary school English teacher

“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.

Your students' work stays yours.

Their writing is not training data and it is not shared with another school. You decide what leaves your classroom.

Scoped to you

Every student, class, and piece of work is walled off per organisation.

You decide what’s shared

Nothing is published without a teacher’s approval.
