PrepAI vs Mathos AI (formerly MathGPTPro)

PrepAI turns lesson notes, PDFs, documents, web links, and videos into quizzes and test papers for educators and trainers. Built by DataToBiz, it offers Standard, Subject, and HOTS quiz modes, academic question banks, and LMS export so teachers can generate assessments without writing every question by hand.

Many quiz builders stop at multiple-choice recall. PrepAI adds HOTS mode aligned to Bloom's taxonomy, a Smart Variations Generator for parallel quiz versions, hosted online assessments with auto-grading, and a REST API for LMS integration. That stack targets schools and training teams that need drafting, delivery, and grading in one workflow.

Teachers, corporate trainers, and EdTech teams use PrepAI to cut assessment prep time. The India pricing page lists a free trial on signup, credit-based solo practice, subscription tiers up to 3,000 quizzes per year, and API access for developers integrating quiz generation.

Mathos AI is an education math solver and tutor that turns a photo, typed equation, or word problem into step-by-step solutions, quizzes, flashcards, and animated lesson videos. One prompt can branch into a worked answer, a 5 to 10 second video first frame, practice cards, and an adaptive review path when you miss a concept.

Generic chatbots hand back a final number with little scaffolding. Mathos breaks problems to their core, repairs the prerequisite you missed before repeating the topic, and the AI Tutor watches your whiteboard steps to catch errors at the exact line where reasoning breaks. The company reports 5 million students and 100 million problems solved.

High school and college students use it for calculus, algebra, and physics homework, while parents get session summaries through a dashboard. The product is free to start with a 3-day trial on paid plans, and an enterprise video API tier offers 3,800 generated minutes per month.
