The maths tutor who draws
Thena is an AI teacher your child can talk to. She draws each step as she explains it, the way their school teaches, until it clicks.
Try 3 lessons freeReception to Year 11. 3 hours of lessons a month for £29, about the price of one hour with a tutor.
Let's share 96 sweets between 4 friends.
Lessons they can see and touch
Thena draws each idea the moment she names it. Children tap, colour in and cross out, and she sees exactly what they did.
Fractions to shade
Children colour in the parts themselves.
Pictures she draws
170 ready to go, and anything else on the spot.
Clocks
Hands that move as she tells the time.
Timelines
History in order, at a glance.
Real money
Pounds and pence, to count and pick.
Hooked by a story
Children listen to a story long before they listen to a fact. So Thena often opens a new idea with one, read aloud from a picture book or told on the board, and the lesson grows out of it. The crow’s pebbles become the jug they measure. The bears’ bowls become the sizes they compare.
They can ask, and ask again
Your child asks out loud or types, on a laptop or iPad. Thena answers, explains it another way, draws it again, and keeps going until it makes sense.
Leo’s lesson, today
Adding two-digit numbers, by voice
- Leo
- Why do we carry the one?
- Thena
- Because 7 add 5 makes 12. That’s one ten and two ones, so the ten moves to the tens column.
Taught their school’s way
What they learn at home matches their classroom, right down to how a sum is set out.

Two months from now
Here’s what ten short lessons a month add up to, for your child and for you.
Today
She finds their level
A short challenge game finds where they really are in each subject, gaps and all.
Let’s find your starting point!
Week 2
What they learn comes back
Each topic they learn returns as a quick warm-up the next day, then three and seven days later, then at longer gaps, so it sticks.
Fractions tricked us last time. Shall we see if they still can?
Week 6
More answers are their own
Her help steps back as they grow, so more of their maths is worked out alone. Six weeks of learning wins their first badge.
You split it into halves first. Nice thinking!
Olive Tree
Month 2
Ten topics learned
About 10 topics secured and 75 questions worked out on their own, with warm-ups keeping the first ones fresh.
Ten topics! That’s your Laurel badge.

You can follow every step in your grown-ups area. Based on about ten lessons a month; every child goes at their own pace.
Help, not answers
When about 1,000 students used a plain AI chatbot for maths practice, they scored 48% higher in practice and 17% lower in the exam that followed (PNAS, 2025). So Thena gives the least help that gets them moving, and each wrong try opens one more step.
- Have a go“What do you think comes next?”
- Look again“Look at the tens column again.”
- Point to the slip“Check what 7 add 5 makes.”
- Teach the idea“When a column makes ten or more, we carry.”
- Do the first step“Let’s do the ones together.”
- Show, then a twin“Watch me. Now you try 48 add 37.”
A four-year-old is shown the way after two tries, a teenager after four, and then gets a twin question to do alone.
Stars for working it out
They earn every star by working something out on their own.
10 stars
25
Wow, 10 stars! Your very first ten!
Working it out alone
A star for each step of a lesson, once they’ve solved a question on it themselves.
Bouncing back
Getting it right after a wrong try wins a badge of its own.
Remembering
Warm-ups they still get right days later count towards the next one.
Coming back
Each week they learn in adds up, and a missed week takes nothing away.

Maya’s lesson, today
Fractions, 14 minutes, 3 stars
- Thena
- Which is bigger, a half or a quarter?
- Maya
- A quarter, because 4 is bigger.
- Thena
- Let’s cut two pizzas and see.
What Thena noticed
- Thinks bigger bottom numbers mean bigger fractions
- Got it on her own after the pizza drawing
- Next: comparing fractions, with a warm-up tomorrow

Lessons grow with your child, from about 12 minutes at age 5 to 30 from age 11. So 3 hours is about 15 lessons a month for a 5-year-old, 10 for an 8-year-old and 6 for a 12-year-old.
Questions parents ask
Is Thena a real person?
No. Thena is an AI: a computer program that teaches. She says so to children, never pretends to be a person, and a grown-up sets up every account.
Which ages and subjects?
From Reception to Year 11: maths, English, science, history and geography, following the National Curriculum, up to GCSE.
What if my child is ahead or behind?
Each child has their own level in each subject, so a child can do maths two years ahead and reading at their own pace. A short challenge game finds the starting point, and you can set it yourself.
Will they actually want to do it?
Thena talks with them, draws as she explains and cheers them on, and they answer out loud, by typing, or by tapping, colouring in and crossing out on her board. Every star and badge is won by working something out alone, so what brings them back is wanting the next one.
Can my child ask her questions?
Yes, at any point in a lesson. They can ask out loud or type, and Thena answers, explains it another way or draws it again until it makes sense.
Will it just do their homework?
No. Thena gives the least help that gets them moving: a nudge, then a hint, and only after a few tries does she show the way, followed by a twin question to do alone.
How much screen time is it?
Lessons grow with them: about 10 minutes for the youngest, and up to about 30 from age 11. Thena never starts the next lesson by herself, and nothing pings a child to come back.
Three lessons, on us
Add your children in two minutes, and Thena finds where each of them is up to. No card needed.
