How an AI multiple choice questions answer generator helps you study

Writing good multiple choice questions takes time, and writing the answer choices so that only one is correct takes even longer. Paste your lecture notes into an AI multiple choice questions answer generator and it drafts questions from the material you actually covered, marks the correct answer, and writes a short explanation for each option.

  • Answer choices are drawn from your own material, not generic trivia.
  • Every option gets an explanation, including the wrong ones.
  • Photos of printed pages are read with text recognition.
  • Questions can be reviewed and rewritten before you study.
Example intro biology questions on cell structure
Which organelle produces most of a eukaryotic cell's ATP?Mitochondria. Most ATP is made by oxidative phosphorylation across the inner mitochondrial membrane during aerobic respiration.
What is the main function of ribosomes?Protein synthesis. Ribosomes read mRNA and link amino acids into polypeptide chains.
True or false: plant cells have a cell wall made mainly of cellulose.True. Cellulose is the main structural polysaccharide in plant cell walls, while animal cells have no cell wall.
Which structure controls what enters and leaves the cell?The plasma (cell) membrane. It is a phospholipid bilayer with embedded proteins that regulate transport.
Where in a eukaryotic cell does the Krebs cycle take place?The mitochondrial matrix. The cycle's enzymes are located in the matrix, not the inner membrane.

Correct answer marked

Each question comes with one marked correct answer, so you can check your work before you study.

Explanations for every option

Explanations say why the right answer is right and why the distractors are wrong, which is where most of the learning happens.

Built from your own material

Questions come from the text you upload, so the quiz matches your course rather than a generic textbook.

How it works

Upload your material

Add a PDF, DOCX, PPTX, text file or a photo of your notes. Photos are read with text recognition.

Choose question types

Pick multiple choice, true or false, or short answer questions. Multiple choice is the default.

Study and check answers

Work through the quiz in your browser and read the explanation after each answer to see what you missed.

The explanations matter as much as the answers. When you pick a wrong option, the explanation tells you which concept you confused, so you can go back to the source and fix the gap. You can also use the same questions as a self-test before an exam, then return to the items you missed.

Free accounts get 3 generations per month and can study in the browser. Plus and Pro add more generations and export options, so you can take quizzes offline or load them into another tool.

Frequently asked questions

How many multiple choice questions should I make from one chapter?

Most chapters can support 10 to 20 questions, which is enough to cover each key term and concept at least once. Start with a smaller set and add more if practice shows you are missing topics.

Are the wrong answer choices worth studying?

Yes. Distractors often reflect the misconceptions that show up on real exams, so reading why each one is wrong builds stronger understanding than memorizing only the correct answer.

Can I export AI-generated quiz questions?

Exports are paid features. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML export for learning management systems.

Can I use a photo of my notes instead of a file?

Yes. Photos of pages are read with text recognition, so you can generate questions from handwritten or printed notes as long as the text is legible.
