AI quiz generator: multiple-choice questions on any subject
An AI quiz generator writes multiple-choice questions about a topic you supply. Lexora produces ten questions with four options each, one verifiably correct answer, and a short explanation of why it is correct — so a wrong answer teaches you something rather than just deducting a point.
At a glance
- Ten questions, four options, one correct answer
- Every answer comes with a written explanation
- Questions are fact-checked against the topic before delivery
- Correct-answer position is varied so you can't pattern-guess
- Useful for revision, pub quizzes, or classroom warm-ups
Why explanations matter more than scores
There is a well-documented effect in learning research called the testing effect: retrieving an answer from memory strengthens it far more than re-reading the material does. The catch is that retrieval only helps if you find out whether you were right. A quiz that shows a score and nothing else wastes the effect entirely, which is why every Lexora question carries its explanation.
Getting more out of a quiz
- Answer before you are confident. A guess you then correct sticks better than an answer you looked up.
- Regenerate the same topic after a day rather than immediately — spacing the repetition is what moves it into long-term memory.
- Read the explanation on questions you got right too; it often adds a detail the question did not test.
- Narrow the topic when the questions feel too easy. "World War II" is broad; "the Battle of Midway" is a genuine test.
Questions people ask
- Can I generate a quiz on any topic?
- Yes. Type the subject in free text and the questions are written for it. Quizzes cost slightly more coins than word puzzles because the app searches live sources for recent topics before writing the questions.
- Are the quiz answers accurate?
- Questions are fact-checked against the topic before they reach you, and each carries an explanation you can judge for yourself. For fast-moving subjects the app consults live sources rather than relying on training data alone.
