KeyStage

A patient AI teacher who explains first, then checks.

How a lesson works

Teach first, then check. Every new idea goes through the same five steps, so your child is never tested on something they haven't been shown. Here is one idea, a quarter, from start to finish.

  1. Explain

    “A quarter is one of four equal parts. Equal is the important word.”

  2. Show

    “Here's a bar in four equal parts. I've shaded one: that's one quarter.”

  3. Do one together

    “Our pizza has four equal slices. Which one shall we shade?”

    That one!

  4. Practise

    “Your turn. Which shape has a quarter shaded?”

    B!

  5. Recap

    “Today you learned what a quarter is. I'll ask you again tomorrow so it sticks.”

Review at the right moment

Each lesson leaves a few flashcards. They come back the next morning, then further apart as your child remembers them, using spaced repetition.

Tests when you want one

“Quiz me on this week” or “quiz me on the tricky bits” in one tap. Questions are read aloud up to Year 6, and marked for you.

Diagrams that are right

Number lines, bar models, clocks, coins, graphs and more come from ready-made templates the teacher fills in, so the picture always matches the maths.

Twelve teachers. Your child picks.

Each one has their own voice and their own way of explaining. Children can switch whenever they like, and every teacher follows the same explain-first lessons.

Something to check

Ava said she was worried about a spelling test. Miss Maple reassured her. Read it in context, then mark it as checked.

Built for children from the start

An AI teacher has to earn a parent's trust. These are the rules it works within.

  • No personal details asked

    The teacher never asks for a surname, school, address or photo. A child's record holds a first name and a school year.

  • Worries go to you

    If your child says something worrying, the teacher answers kindly, points older children to Childline, and flags it to you.

  • No adverts, ever

    Nothing in a lesson is trying to sell your child anything.

  • Your data is not for sale

    We never sell your family's data or use it for advertising.

  • Careful pictures and clips

    Photos come from Wikipedia. Videos are short educational clips found with YouTube's strictest SafeSearch.

  • Stays on topic

    The teacher gently steers off-topic chat back to learning, and keeps a child-friendly tone for their age.

Questions parents ask

Is KeyStage a replacement for school?
No. It's one-to-one help at home that follows the same National Curriculum your child's school does. You can tell it what they're learning at school this week, so practice at home lines up with lessons in class.
Which years does it cover?
Year 1 to Year 11: Key Stages 1 to 4, including the GCSE years, across 12 subjects. Lessons, language and pace adjust to your child's year, and younger children can listen rather than read.
Does it work on an iPad?
Yes. It runs in the browser on iPads, Android tablets, phones, Chromebooks and computers, and you can add it to the home screen like an app. Talking needs a microphone; children can type their answers instead.
How is my child's data used?
Only to run and tailor lessons. We ask for a first name and school year, never a surname, school or photo. Lessons are saved so you can read them and so the teacher remembers what your child has learned. We use AI services to produce the teacher's replies and voice. We never sell data or show adverts. The privacy policy has the details.
Can I cancel?
Yes, at any time, from the grown-ups' area. There's no minimum term, and the three free lessons don't need a card at all. See pricing for how billing works.
