How QuizShip Generates Good Quizzes while Keeping Subscriptions Profitable
· 9 min read
QuizShip turns a topic or a PDF into a quiz, and Claude writes the questions. Each subscription includes a monthly number of AI generations, so every generation is a cost that comes out of the subscription's margin.
The first version cost a median of $0.037 per quiz, but a 40-question quiz took 104 seconds, past the 90-second limit for a generation. The pipeline I run now writes that quiz in about 10 seconds, at about the same cost as before. This post covers how it works, the attempts that got it there, and why it's a fixed pipeline rather than an agent. I used Claude Code to write the evaluation scripts and run the experiments.
