Why custom questions beat a cosmetic reward

Students searching for free Gimkit skins usually want a reason to keep playing and studying. Cosmetics can add fun, but they don't change what you remember from a unit.

  • Quiz questions generated from your own PDFs, slides or notes
  • Multiple-choice, true/false and open questions with explanations
  • Free plan includes 3 generations per month and browser study
  • Paid plans add exports to PDF, DOCX, QTI 2.1 and Moodle XML
Example biology quiz questions with answers
Which organelle produces most of a cell's ATP?The mitochondrion. It carries out cellular respiration, which converts glucose and oxygen into ATP.
True or false: plant cells lack a cell membrane.False. Plant cells have a cell membrane just inside the cell wall, and it controls what enters and leaves the cell.
What is the main job of ribosomes?Protein synthesis. They read mRNA and link amino acids together into polypeptide chains.
In which phase of mitosis do chromosomes line up along the cell's center?Metaphase. Spindle fibers attach to the centromeres and align the chromosomes at the metaphase plate.
What does it mean that a cell membrane is semipermeable?It lets some molecules pass while blocking others. Small nonpolar molecules cross more easily than large or charged ones.

Questions from your own material

Upload a PDF, DOCX, PPTX, text file or a photo of a page and get questions drawn from what you actually need to learn.

Explanations on every answer

Each multiple-choice, true/false and short-answer question comes with a reason, so wrong answers become study moments.

Export for live play

Paid plans export to PDF, DOCX, QTI 2.1 and Moodle XML, so you can bring your questions into the tools your class already uses.

How it works

Upload your notes

Add a PDF, slide deck, document or text file. Photos of pages are read with text recognition.

Choose a question type

Pick multiple choice, true/false or open questions and set how many you want.

Study or export

Practice in your browser on the free plan, or export your set on a paid plan.

A quiz built from your own lecture notes or textbook chapter targets the material your test will cover. Each question includes an explanation, so you learn why the right answer is right instead of just clicking through a game.

Frequently asked questions

How many quiz questions should I write for a biology unit?

Aim for roughly 15 to 25 questions per unit so you cover each major term and process. Spread them across question types so you practice both recall and application.

What makes a good multiple-choice question for studying biology?

Each wrong option should be a plausible mistake, such as confusing mitosis with meiosis, rather than an obviously wrong choice. Write one clear correct answer and keep the options similar in length.

Which features come with paid plans?

Plus costs $39 per year or $7.99 per month and adds unlimited generations plus PDF, DOCX, Anki and CSV export. Pro costs $14.99 per month and adds a stronger AI model, bulk upload, QTI 2.1 and Moodle XML export.

Does DeckOwl cost anything to start?

The free plan includes 3 generations per month and studying in the browser, with no exports. You don't need a credit card to start, and students with a school email get 40% off.
