Frequently Asked Questions
How are quizzes generated from PDFs?
When you upload a PDF, our AI reads the document, identifies key concepts, and creates multiple-choice questions with one correct answer each. The whole process takes about 30 seconds and works with textbooks, lecture notes, articles, and other study materials.
Do I need an account to take or create quizzes?
No account is needed. You can browse, solve, and even generate quizzes as a guest. Creating an account lets you track your history, manage your quizzes, and publish them to the public library.
Can I share my quiz results with others?
Absolutely. After completing a quiz you get a unique results link you can share via email, chat, or social media. Recipients can see your score and try the same quiz themselves.
What subjects and difficulty levels are covered?
The library spans STEM subjects (math, physics, chemistry, biology), humanities (history, languages, art), professional fields (law, medicine, business, technology), and more. Difficulty depends on the source material — upload an introductory textbook for easier questions or an advanced paper for a tougher challenge.
What types of PDF documents work best?
Textbooks, lecture slides, study guides, and articles with clear factual content produce the best quizzes. The AI extracts key concepts and turns them into multiple-choice questions, so well-structured documents with headings and paragraphs give the strongest results.
How is my score calculated?
Your score is the number of correct answers divided by the total number of questions, shown as a percentage. After submitting you can review each question to see which answers were correct and where you went wrong.
Can I embed a quiz on my own website?
Yes. Every quiz has an embed option that gives you an iframe code snippet. Paste it into your blog, LMS, or any HTML page and the quiz will load interactively for your visitors — no extra setup needed.
Is there a limit to how many quizzes I can take?
There is no limit on solving quizzes — take as many as you like, as often as you want. For generating new quizzes from PDFs, free users have a monthly quota. Upgrade to Premium for a higher generation limit.
