# Cuiz AI

> Cuiz AI turns any document — PDF, DOCX, PPT, or TXT — into an interactive practice quiz or flashcard deck powered by AI. Built for students, teachers, and self-learners who want active recall and spaced repetition without manual card creation.

Cuiz AI is a free web app at https://cuiz-ai.com. Upload a document, choose a difficulty and language, and get an AI-generated quiz or flashcard deck in seconds. Quizzes can be retaken, exported as PDF/DOCX, and shared via privacy-first opt-in links. Flashcards use the SM-2 spaced-repetition algorithm. The free plan covers several quizzes per month; paid plans unlock unlimited usage.
