Frequently Asked Questions About Quiz Generation

Addressing common concerns regarding file handling and assessment export functionality.

How does the AI ensure the questions are accurate to my material?

The AI uses advanced natural language understanding (NLU) to parse the semantic structure of your input files (PDFs, slides, text). It prioritizes extracting core concepts, definitions, and relationships outlined in your source material to construct valid, context-specific multiple-choice questions.

What types of files can I upload to generate a quiz?

We support a wide range of common academic formats, including PDF, DOCX, and PowerPoint (PPT/PPTX). You can also input text directly or upload standard image files containing legible text.

Can I export the generated quiz along with the answer key?

Yes. Our platform is designed for interoperability. You can export quizzes in PDF format for easy printing, Word (DOCX) for editing, and standardized educational formats like QTI 2.1 and Moodle XML, ensuring the answer key and explanations are retained or easily mapped.

Is the question generator completely free to use?

We offer a robust free tier that allows you to generate a certain number of quizzes monthly. For intensive users needing unlimited generation credits or access to our most advanced, high-capacity AI model, we offer a paid subscription plan.
