How it works

Step 3 of the loop

Taught the mistake — not handed the answer.

When a question comes back wrong, your child taps it and Ms. Lumi talks them through it out loud. She asks the right questions until they get there themselves — the way a good tutor would.

  1. 1

    Tap a question they got wrong

    On any marked page, the questions your child lost marks on become a one-tap "explain this". No typing, no searching — straight from the mistake to help on it.

    Ms. Lumi talks them through it

    A live voice conversation begins. She works from the actual question and your child’s answer, nudging them with questions rather than reciting the solution — so the understanding sticks.

    It ends when they’ve got it

    A session runs up to five minutes; if they’re close to the finish line they can add five more. They come away understanding the step they were missing — ready to try it again.

Live help on a mistake

It’s a real back-and-forth voice session anchored to the exact question — not a chatbot and not a video to sit through. Your child explains their thinking out loud and gets guided to the gap.

The whiteboard Ms. Lumi draws

Turn on the whiteboard and she sketches as she explains — a model drawing, a worked step, a quick diagram — so visual ideas land the way they would on a real teacher’s board.

Help while practising — not just on past mistakes

Ms. Lumi isn’t only for diagnosing errors after marking. While working through any exam paper on screen, your child can drag a box around any daunting question and tap "Send to Ms. Lumi". She unblocks their reasoning immediately, turning homework dread into confidence before they even submit.

Questions parents ask

Does it just give the answer?

No — that’s the point. Ms. Lumi guides Socratically with questions and hints so your child reaches the answer themselves. Understanding the step is what moves the next mark.

What does a session cost?

One credit gets a five-minute session. If they’re nearly there, a +5-minute extension is one more credit. No subscription.

Is it safe for my child?

It’s a voice session tied to your family account, and the full transcript is visible to you — so you can see exactly how your child was taught.

Can my child ask Ms. Lumi for help before submitting their paper?

Yes. While doing practice on the digital worksheet, they can drag a box around any question they are stuck on to start a real-time voice lesson with Ms. Lumi immediately.
