AI Study & Practice Test Platform
AI SaaS solution to help students in study and practice. We charge during checkout.
In plain English
TestWhiz, from Sadek, helps students study by practicing instead of only rereading notes. Their own material becomes questions, explanations, and a study plan, and they pay when they check out. A free level is there to try, with a paid plan shaped for a student budget. Sadek finds learners through search and student groups. The AI does most of the practice building, the billing, and the first steps for a new person, while Sadek keeps an eye on quality, helps learners, and deals with odd situations.
