Build a quiz from your own reading

Teachers and students often have a long PDF and one evening to test themselves on it. An AI quiz creator from PDF reads the text, picks out the key ideas and writes questions with explanations you can check against the source.

  • Upload a PDF, slides, DOCX or a photo of notes
  • Get multiple-choice, true/false and open questions
  • Read an explanation for every answer
  • Export to PDF, DOCX, QTI 2.1 or Moodle XML on a paid plan
Example chemical bonding quiz questions
Why does sodium chloride form an ionic bond instead of sharing electrons?Sodium transfers one valence electron to chlorine, so both ions get full outer shells and the attraction between opposite charges holds them together.
Which molecule has a polar covalent bond: Cl2 or HCl?HCl. Hydrogen and chlorine differ in electronegativity, so electrons are pulled toward chlorine; Cl2 has identical atoms and is nonpolar.
How many bonding electron pairs are shared in a nitrogen molecule, N2?Three pairs, forming a triple bond, because each nitrogen atom needs three more electrons to complete its octet.
Why can metals conduct electricity?Metallic bonding lets valence electrons move freely through a lattice of positive ions, so they carry charge when a voltage is applied.
Is a hydrogen bond a true covalent bond?No. It is a weaker attraction between a partially positive hydrogen and a nearby electronegative atom such as oxygen, nitrogen or fluorine.

Reads your own files

Upload a PDF, DOCX, PPTX, plain text or a photo of a page. Text recognition reads scanned pages too.

Three question types

Generate multiple-choice, true/false or short answer questions, each with an explanation for the correct answer.

Export when you need it

Plus adds PDF and DOCX export. Pro adds QTI 2.1 and Moodle XML export for learning management systems.

How it works

Upload your material

Add the PDF, slides or notes you are studying from.

Choose a question type

Pick multiple choice, true/false or open questions for your quiz.

Take the quiz

Answer in the browser, read the explanations and retake the questions you missed.

The tool supports multiple-choice, true/false and open questions, so you can mix quick recall with questions that ask you to explain a concept in your own words.

The free plan lets you take quizzes in the browser with 3 generations per month. Exports to PDF and DOCX require Plus, and QTI 2.1 and Moodle XML export require Pro, so check the plan before you build a course quiz.

Frequently asked questions

How many quiz questions should I make from one chapter on chemical bonding?

Most chapters work well with 10 to 15 questions. Mix multiple choice for definitions with open questions that ask why ionic and covalent bonds form.

How do I study chemical bonding with practice quizzes?

Retake the quiz until you can explain each answer, not just pick it, and read the explanations for every question you miss. Spacing reviews over several days helps rules like electronegativity and octet stick.

Is exporting quizzes free?

No. The free plan lets you study in the browser with 3 generations per month. PDF and DOCX export are on Plus, and QTI 2.1 and Moodle XML export are on Pro.

Do I need a credit card to start?

No. You can start on the free plan without a credit card, and students get 40% off with a school email.
