Frequently Asked Questions About AI Quizzes

Get clarity on how our advanced system works to generate your custom practice materials.

How does the AI generate explanations for incorrect answers?

The AI analyzes the underlying concepts related to the correct answer and contrasts them with the distractors (incorrect options). It then generates specific pedagogical text explaining why the distractor does not align with the factual context established in your source material.

What document formats can I upload to generate my practice quiz?

We support a wide array of inputs to ensure maximum compatibility. You can upload PDF documents, Microsoft Word (.docx), and PowerPoint (.pptx) files, or even images containing text.

Besides PDF and Word, what other export standards do you support?

For compatibility with institutional Learning Management Systems (LMS), we support QTI 2.1 (Question & Test Interoperability) and Moodle XML formats, allowing seamless integration into most academic platforms.

Is there a limit to how many quizzes I can generate for free?

The core service offers a generous free tier allowing you to test the functionality. For heavy users or those requiring access to our most advanced, powerful AI models, we offer affordable paid plans with higher generation credits.
