Our AI option explanation generator targets this gap by ensuring every practice item reflects your exact teaching materials.

  • Achieve better assessment coverage.
  • Promote active recall over passive review.
  • Save faculty dozens of hours per semester.
  • Support complex, multi-format export standards (QTI, Moodle).

This specialized tool ensures that practice tests drive deeper engagement, turning simple knowledge checks into powerful learning opportunities supported by clear, immediate AI feedback.

Frequently Asked Questions for Educational Users

Answers regarding our AI quiz creation engine and platform capabilities.

How does the AI generate explanations for incorrect options?

The AI analyzes the conceptual difference between the correct answer and the distractors (incorrect options). For incorrect options, the explanation field will be empty, adhering to standard assessment logic. However, the correct option always receives a detailed explanation justifying why it is the right answer based on your source material.

What types of files can I upload for content ingestion?

We support robust ingestion for PDF documents, Microsoft Word (.docx), PowerPoint presentations (.pptx), and various image formats. You can also simply type in a descriptive prompt detailing the subject matter you need assessed.

Can I export the generated quizzes for offline use or LMS import?

Yes, flexibility is key for schools. You can export finalized quizzes directly into PDF, editable Word (.docx) files, QTI 2.1 (for standardized import), and Moodle XML format for easy deployment within major Learning Management Systems.

Is the option explanation generator free, or are there paid tiers?

The core functionality is available for free, allowing you to test the quality of the AI-generated quizzes. Our paid plans unlock higher monthly generation credits and access to our most advanced, specialized AI model for even greater nuance in question design.
