Frequently Asked Questions About AI Quiz Generation

Addressing common concerns regarding source material and assessment output.

How does the AI accurately generate diagnostic questions from my documents?

The AI uses advanced natural language processing (NLP) models to identify key concepts, definitions, processes, and relationships within your input (PDFs, PPTs, etc.). It then structures these into questions designed to test conceptual understanding, not just rote memorization.

What types of files can I upload to generate my quizzes?

We support common educational document formats including PDF, DOCX, and PowerPoint files, as well as direct image uploads (like lecture slides screenshots). You also have the option to simply type a descriptive text prompt.

Can I export the resulting diagnostic quizzes for offline use or LMS integration?

Yes. Flexibility is key to our tool. You can export quizzes in standard formats like PDF and Word (DOCX), or use specialized educational standards like QTI 2.1 and Moodle XML for seamless integration into various Learning Management Systems.

Is this powerful automatic quiz generator free to use?

We offer a generous free tier that allows you to experience the core functionality. For heavy users, or those requiring access to our most advanced, high-context AI models and higher generation limits, we offer competitive paid subscription plans.
