Directly input paragraphs, complex academic papers, or large documents. The AI parses structure and intent, creating assessment items precisely aligned with your source material.

AI-Powered Answer Rationales

For every multiple-choice option, receive a detailed explanation for the correct answer, explaining *why* it is superior and how it connects back to the core text concepts.

Mastery Through Export Flexibility

Practice interactively, or export finalized assessments seamlessly into PDF, Word (DOCX), QTI 2.1, or Moodle XML for offline study sessions or LMS integration.

Deepen Reading Comprehension Skills with Automated Rationale Generation

Relying on basic multiple-choice quizzes for reading comprehension risks superficial learning. True mastery requires understanding the justification behind every choice. Our specialized AI quiz generator focuses specifically on building robust answer rationales.

  • AI analyzes textual evidence for question creation.
  • Generates MCQs demanding critical inference, not just recall.
  • Provides the essential explanation/rationale for correct options.
  • Supports seamless export into common educational formats.

By demanding detailed justification from the AI, you ensure your practice tests actively train your brain in complex textual analysis, preparing you thoroughly for high-stakes examinations.

Frequently Asked Questions About AI Assessment Creation

Get clarity on how we transform your materials into high-utility practice tests.

How does the AI generate detailed answer rationales?

The AI performs semantic analysis on the source document relative to the question stem. The rationale for the correct answer cites or paraphrases the specific textual evidence that validates the choice, providing strong evidence-based learning support.

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

We support uploads for common document types including PDF, DOCX, and common presentation files (PowerPoint). You can also input text directly or use image uploads for scanned material.

Can I export the resulting reading comprehension quiz for my LMS?

Yes. We support exporting your generated assessments in highly compatible formats like QTI 2.1 and Moodle XML, alongside standard PDF and Word (DOCX) files for easy use offline.

Is the AI quiz generator completely free to use?

A foundational version of the tool is available for free, allowing you to test the quality of the AI-generated quizzes and rationales. Access to higher generation limits and the most advanced AI model requires a paid subscription.
