Frequently Asked Questions

Get quick answers about the AI generation process and format compatibility.

How does the AI generate questions with rationales?

The AI parses your input material, identifies critical terms and relationships, and constructs distractors (incorrect options) based on common misunderstandings. The rationale then explains the linguistic or contextual reason why the correct answer applies and why the distractors do not.

What file formats can I upload to generate my vocabulary quizzes?

You can upload common academic formats including PDF, DOCX, and PowerPoint files. You can also input questions or terms directly via image upload or by pasting raw text.

Can I use these AI-generated quizzes outside the platform?

Yes. We support exporting your generated MCQs with all associated answer keys and rationales into flexible formats, including PDF, Word (DOCX), QTI 2.1, and Moodle XML.

Is the AI vocabulary quiz generator completely free to use?

The core functionality is free, allowing you to generate a limited number of quizzes. For unlimited generation credits and access to our most advanced reasoning model, users can upgrade to our paid subscription plan.
