Inspiration

I was tired of juggling screenshots, ChatGPT windows, and messy Google Docs every time an exam popped up. The “aha” moment: one button that cleans raw notes and spits out study tools instantly. Quizzy is that button—born from our own late-night cram pain.

What it does

  1. Paste notes or upload a file
  2. Quizzy auto-generates flashcards and a five-question quiz
  3. Study in a clean, distraction-free UI (dark/light)
  4. Track sets and scores in a mini dashboard
    Free for light use; $3.99/mo unlocks unlimited sets and a class-pack for teachers.

How we built it

  • Bolt.new scaffold → regen prompts for the notebook vibe
  • React + TypeScript + TailwindCSS for the front-end
  • Framer Motion for card flips and hero animations
  • Claude Sonnet 4 Edge Function cleans text → JSON (cards + quiz)
  • Supabase (auth, Postgres, RLS policies)
  • Stripe Checkout for premium plans
  • Deployed to Netlify straight from Bolt

Challenges we ran into

  • Supabase downtime 48 h before deadline—mocked local store to keep moving.
  • Claude loved copying entire sentences; extra prompt rules fixed “wall-of-text” definitions.
  • Balancing playful doodle UI with accessibility (WCAG contrast fixes at 2 a.m.).

Accomplishments that we're proud of

  • Live demo with real Stripe payments in ten days.
  • 90 %+ Lighthouse scores on first deploy.
  • Teacher pilot: one class created 120 sets in 24 hours.

What we learned

  • Good prompts > complicated code when working with LLMs.
  • Start with mock data; swap in the database only when the schema is solid.
  • Tiny motion and sound effects make studying feel less like work.

What's next for Quizzy – Study Smarter

  • PDF + image import (OCR).
  • Adaptive spaced-repetition scheduler.
  • LMS plug-ins for Google Classroom & Canvas.
  • Spanish, Portuguese, German translations.
  • Public marketplace for user-made study decks.
