Find quick answers regarding file compatibility, generation logic, and plan options.

How does the AI actually generate the questions from my uploaded files?

The AI uses advanced Natural Language Processing (NLP) to understand the context, hierarchy, and key factual information within your PDFs or documents. It then formulates assessment items designed to test comprehension, application, and recall based strictly on that provided source material.

What types of files can I upload to create my diagnostic quiz?

We support common academic formats, including PDF, DOCX, and PowerPoint (PPT/PPTX). You can also upload image files containing text, or simply type a descriptive prompt to initiate quiz creation.

Can I export the practice quizzes I create?

Absolutely. We prioritize flexibility. You can export quizzes to PDF for printing, Word (DOCX) for easy editing, or use industry-standard formats like QTI 2.1 and Moodle XML for seamless integration into most Learning Management Systems.

Is the AI practice quiz generator free to use?

Yes, there is a robust free tier available which allows you to generate a limited number of quizzes using our standard model. For heavy users or those requiring our most advanced AI processing capabilities, we offer paid plans with increased credit limits.
