Does this sound familiar?
You teach well. You know exactly which child is stuck where. And most of your time goes on typing questions, laying out pages and writing answer keys — again and again.
- Worksheets you find online are locked PDFs pitched at the wrong level
- Making your own means typing equations, spacing answers, then writing a separate key
- The whole class gets one version, so they copy — and a version B means starting over
- Then you mark it all yourself, page by page
The problem is not that you are not good enough. You are spending a teacher's time doing a printer's job.
What this is not
- Not a library of finished PDFs you cannot edit
- Not an AI chatbot whose answer key you have to check yourself
- Not a foreign platform with no Thai and a licence that forbids reselling
It is a generator that computes with real mathematics rather than guessing an answer from language.
What actually makes it different
Questions are computed, not guessed
Every question is built from a mathematical rule and then re-checked with SymPy before you ever see it — roots substituted back into the equation to confirm. That is a different thing from a language model composing an answer that merely looks right.
A fresh set for the whole class in one click
Want version A, B and C so nobody copies? One button. Every number changes, and each key matches its own version.
Kindergarten through university
41 topic areas, from picture counting for the youngest to calculus, statistics and linear algebra. One teacher covering several year groups needs one place.
Thai and English from the same file
Switch the worksheet's language — works for Thai classrooms and English programme classes alike.
Assign online and let it mark
Build a class, add students, assign the worksheet, and let the marking and the gradebook happen for you — with QR attendance built in.
You may genuinely resell what you make
Worksheets you create are yours to sell under our commercial licence — something most international platforms forbid.
Every image on this page is a worksheet the system actually generated, not a mock-up.
No card required. Usable the moment you sign up.
And for the students in your class who are heading to a contest
Most teachers have two or three students who left the regular worksheet behind a while ago, and a parent asking "how should my child prepare for the olympiad camp?" Today's answer is a scattering of past-paper PDFs and an expensive tutor.
The competition arena sits in the same account you build worksheets in. Students can work through it on their own, you can set it as classwork, and there is nothing to prepare.
- Five bands from school level up to international olympiad — climbed one step at a time
- Timed mock papers of 6-10 questions, marked the moment they submit, with a full worked solution for every one
- 49 topics across number theory, algebra, geometry, combinatorics and Diophantine equations
- A weekly leaderboard and a weekly timed cup, so coming back to practise is their idea rather than yours
Said plainly, because it should be: a band name like "equivalent to POSN camp 1" is a difficulty comparison. Every problem is generated fresh, not a real past paper — so we are not borrowing anyone's exam copyright, and the bank is not a fixed number of sheets but a new draw every time.
Mock exams need an account (a free one runs 5 a month); topic practice needs no login at all.
We will not invent numbers we do not have
We have only just opened to our first group of Thai teachers, so we have no wall of reviews to show you — and we are not going to fabricate one.
What we can show you is the product. Go and generate a real worksheet, free, right now. You do not have to take our word for anything.

What teachers ask
Do I need to be good with computers?
No. Pick a topic, pick a level, press generate, press print. Like Word, without the typing.
How much can I trust the answer keys?
Every question is re-checked with SymPy before it is issued, and no language model writes the answers. We still will not claim they can never be wrong — if you find one, tell us and we fix it and re-check the whole topic.
Does it fit the Thai curriculum?
Yes — organised by Thai year groups from kindergarten through P1–P6, M1–M6 and university level.
Can I really sell what I make?
Yes, under our commercial licence, which is written plainly in the terms.
Is cancelling difficult?
You cancel yourself from the subscription page and keep access until the period you have paid for ends.
Next term is coming either way
There is only one question left: how many more Sunday nights do you want to spend typing worksheets?
No card. Under a minute to sign up.
