I built an AI tool that turns your notes into quizzes (Next.js + Claude API

I just launched a side project called Quizo AI and wanted to share it with the dev.to community.

What it does
You give it a file, paste some text, drop a URL, or just type a topic — and it generates a quiz, flashcards, or an AI tutor session from it. The goal was to make studying less tedious by automating the part where you'd normally write your own questions.

What was tricky
Handling multiple input types (PDF, DOCX, images, plain text, URLs) and getting the AI output structured reliably enough to render as proper quiz UI took some iteration. Also building an XP/leveling system to make repeated use feel less boring.

Try it
It's free, no sign-up required to try: https://quizo-ai.vercel.app/
Would love feedback — what's confusing, what's missing, or whether this is something you'd actually use for studying. Happy to answer questions about the implementation too.
