Generate a quiz and matching study sheet for any topic

Describe what you’re studying, get an interactive quiz and a formula-first sheet side by side, then customize both by hand until they match how you learn.

First generation is free. Sign in with email or Google, enter a topic, and we’ll build your first pack. No card required.
Pay only for more generations. Editing and customizing stay free. Buy pack credits when you want another AI pass on a new topic.
We’re looking for early users. Prep is in beta. Try it, tell us what works and what doesn’t, and help shape what students get next.
