Paste a YouTube link and get a quiz. The app reads the video's transcript, writes multiple-choice questions with AI, and saves them as a Google Form.
The idea
Teachers and students watch a lot of YouTube. Quiz Maker turns any video into a multiple-choice quiz in a few seconds, and can drop it straight into Google Forms so it's ready to hand out.
How it works
The server fetches the video's transcript and asks Google Gemini for questions against a strict JSON schema, so every answer comes back in a shape the app can use. The quiz can be taken on the page, or sent to a small Google Apps Script that creates a real Google Form in Drive, with no extra sign-in for the user.
The hard parts
AI output has to be reliable, not just good. The strict schema stops malformed quizzes, and the prompt makes the questions read like they're about the video (never "the transcript"). Running on AI free-tier limits meant building per-IP rate limits, a daily quota tracker and a free tier of three quizzes a day, with Pro subscriptions through Stripe.
