What the free plan covers and when to upgrade

Teachers rarely have spare time to write a quiz from scratch after a unit ends. A free quiz maker for teachers can start from the slides, handouts or notes you already have. DeckOwl reads PDF, DOCX, PPTX, plain text and photos of pages, then drafts multiple-choice, true/false or short-answer questions, each with an explanation you can check before using them.

Frequently asked questions

What makes a good multiple-choice distractor for a classroom quiz?

A good distractor is a plausible wrong answer that reflects a common misconception, such as confusing mitosis with meiosis. Avoid options that are obviously false or that give away the answer through length or wording. Review each draft quiz to make sure only one option is clearly correct.

How should I check AI-generated questions before using them with students?

Read each question against your own lesson material and confirm the correct answer and explanation. Remove or rewrite any question that tests something you did not teach. Spot-checking a few questions from each section is a quick way to catch errors.

Does DeckOwl work offline?

No. DeckOwl is a browser-based tool and is not an offline app. Free plan users can study generated quizzes in the browser, and exports require a paid plan.

Which plan do I need to export a quiz to Moodle XML?

Moodle XML export is part of the Pro plan at $14.99 per month. Plus, at $39 per year or $7.99 per month, includes PDF, DOCX, Anki and CSV export. Students with a school email get 40% off.
