Quidger: AI Quiz & Test Maker

Stop re-reading and start testing yourself. Quidger turns your own PDFs, YouTube lectures, and notes into a real practice test in seconds, then shows you what you got wrong and why.

Upload your material. Pick how many questions you want. Take the quiz. Every answer comes with a clear explanation and a citation pointing to the exact slide, page, or timestamp it came from. Retest the topics you miss until they stick.

Still confused by an answer? Tap "Ask why" to chat with an AI tutor that only uses your uploaded material — no generic answers, everything cited back to your source.

Studying from English material but thinking in another language? Get your questions and explanations in English, Español, বাংলা, हिन्दी, or Français.
