Turn anything into
an interactive quiz

Quiddio supports a wide variety of content types! You can use PDFs, Word documents, YouTube videos, websites, Wikipedia articles, and more. Our AI extracts and processes content from almost any source to generate high-quality quizzes.

You earn XP (experience points) for each correct answer during quizzes and learning paths. These points contribute to your ranking on both personal space leaderboards and the global QuizHero leaderboard, creating a competitive and engaging learning environment.

Learning paths are personalized, progressive sequences of questions that guide you through your study material systematically. They adapt to your performance and use spaced repetition (SM-2 algorithm) to optimize knowledge retention.

We use the SM-2 algorithm to determine the optimal timing for reviewing questions based on your performance. Questions you struggle with appear more frequently, while mastered concepts are spaced out over longer intervals.

You get detailed statistics including performance by category, question-level accuracy rates, tracking of XP progress, and comprehensive insights into your learning patterns to help identify areas for improvement.
