Why we built this

So you never find out too late.

One teacher, thirty kids, no time. That's who we built it for — and why.

🎯

Who it's for

Teachers who've just taught something and honestly don't know if it landed. If you've ever thought "are they actually with me?" — it's for you.

💡

Why we built it

AI broke the old signals. Homework proves nothing now, and by the time the test lands, the class has moved on and that child is lost. We wanted back the one check that can't be faked — a child explaining it themselves.

The problem

The signals you relied on just stopped working.

You've always known who got it. Not because of a test — because of the small stuff. That's gone.

📄

Homework proves nothing now

AI writes the essay, solves the maths, answers the questions. The work looks perfect — and tells you nothing about the child who handed it in.

🧑🏫

30 kids, one of you

You can't sit with every pupil and ask "explain this to me" — there aren't enough hours. So you never really know until the test.

🤫

The quiet one slips away

The kids who struggle don't shout about it. They nod, copy, stay quiet — and drift. You find out too late.

How it works

Two minutes. Whole class. No marking.

Students have a short conversation. You get the truth.

You pick the topic

Type what you taught. The AI writes the questions — you edit or bin any you don't like. They're yours.

Students explain it

They join with your class code and answer in their own words. No multiple choice — no guessing. If they waffle, it digs.

You see the truth

Green, amber, red across the class — plus what each pupil actually said, in one click.

Why it works

You can fake an answer. You can't fake understanding.

There's no answer to copy. No essay to lift, nothing to paste — they have to explain it themselves.

There's nothing to guess. No A-B-C-D, no lucky 1-in-4. And if they waffle, it digs until the truth shows.

Kids can't tell you what they're stuck on. So we don't ask. It finds the gap — so you know exactly where they're stuck.

The gap, named

They can't say what they don't understand.
So we find it for them.

You can't ask a child to point at their own blind spot — if they could, they wouldn't be stuck. You don't have to. They just answer, and the exact break shows up.

They said "1/4 is bigger than 1/3 — because 4 is bigger than 3."
What's missing They're reading the bottom number as a size, instead of understanding that more pieces means smaller pieces.

"I used to find out in the test. By then it's too late — the class has moved on and that child is lost." Every teacher, everywhere.
