Common questions
Are these worksheets really free?
Yes. The Free plan lets you generate up to 30 worksheets per month at no cost, with a watermark. Paid plans start at $6/month, remove the watermark, and allow unlimited generation.
Can I get Thai-language addition worksheets?
Yes. Switch the language to Thai and word problems adapt automatically — Thai names, baht currency, and natural Thai phrasing. The number layout stays identical so worksheets work in bilingual classrooms too.
How is this different from an AI worksheet generator?
AI generators like ChatGPT can produce wrong answers (hallucinations). MathPrepAI builds every problem from its answer using SymPy, a professional symbolic math library, then verifies the result before you see it. The answer key is guaranteed correct.
Can I adjust the number of problems and difficulty?
Yes. Choose the number of problems (anywhere from 5 to 50), difficulty (Easy / Medium / Hard), and language (English / Thai) before generating.
