Frequently asked questions
Quick answers about pricing, grade levels, languages, and accuracy.
How is MathPrepAI different from ChatGPT?
ChatGPT generates worksheets using a language model — meaning it can produce confidently wrong answers (hallucinations). MathPrepAI uses symbolic mathematics (SymPy) to generate and verify every single problem. 100% guaranteed correct.
Which grade levels does MathPrepAI cover?
All of them — kindergarten counting through high-school and university math, across 37 modules (counting, arithmetic, fractions, decimals, algebra, geometry, trigonometry, calculus, linear algebra, and more).
How does the free plan work?
Free accounts can create 30 worksheets per month — no credit card required. There are no credits to buy or track. New users also get a 14-day Founder Pass with full Creator-level access so you can explore every feature before deciding.
Can I cancel my subscription anytime?
Yes — cancel anytime. You keep access until the end of your billing period. If you cancel within the first 7 days, we issue a full refund.
What languages are supported?
Phase 1 supports English and Thai — for both the UI and worksheet content. Simplified Chinese is planned for Phase 2.
Do worksheets export as PDF?
Yes. Every worksheet is rendered to a print-ready PDF with clean, textbook-quality math typesetting.
Can I use generated worksheets commercially (e.g., KDP or Teachers Pay Teachers)?
The Creator tier ($39/mo) includes a commercial license, letting you sell worksheet packs on platforms like KDP or Teachers Pay Teachers. Light and Personal tiers are for personal classroom use only.
Is there a free tier?
Yes — the Free plan gives you 30 worksheets per month with a watermark. New signups also get a 14-day Founder Pass (full Creator-level access, no watermark) to experience the complete product before committing.
Will the printed worksheets look good?
Yes. Every worksheet is rendered to a clean, print-ready PDF with textbook-quality math typesetting — crisp at any print size, with generous spacing for younger students and proper layout for fractions, equations, and figures.
Are the worksheets aligned to a curriculum (Common Core / สสวท)?
The topics and difficulty bands are designed around standard school curricula, including US Common Core and Thailand's Basic Education Core Curriculum (สสวท). You choose the grade level and difficulty, so you can match exactly what you're teaching.
Do my students get the same problems every time?
No. Every worksheet is generated fresh, so you can hand out a different version to each student or class and never run out — great for practice sets, retests, and anti-cheating.
Can several teachers share one account?
Each subscription is for one teacher. For departments or whole schools that need multiple seats and a shared library, Team and School plans are on the way — contact us if you'd like early access.
How many times can I download a worksheet? Do PDFs expire?
Paid plans let you generate unlimited worksheets, and your library is saved so you can re-download any sheet any time — PDFs never expire. The only limit is total storage per tier (Light 500 / Personal 2,000 / Creator unlimited).
