Joining a live game versus making your own quiz

Most people typing Quizizz game join are holding a code on a classroom screen and need to get into the session before it starts. That is a live game hosted by another service, and DeckOwl does not host games, display join codes or run real-time sessions.

  • Questions are based on the notes or slides you upload, not a generic question bank.
  • Multiple choice, true/false and short answer formats are available.
  • Every question includes an explanation of the correct answer.
  • Students get 40% off Plus or Pro with a school email.
Example biology quiz questions with answers
What organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which converts glucose and oxygen into ATP.
True or false: DNA replication is semi-conservative.True. Each new double helix keeps one original strand and gains one newly synthesized strand.
Which phase of mitosis separates sister chromatids?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.
What is the main function of ribosomes?Protein synthesis. They translate mRNA into a polypeptide chain.
What molecule brings amino acids to the ribosome during translation?tRNA. Each tRNA matches a codon on the mRNA through its anticodon.

Built from your material

Upload a PDF, DOCX, PPTX, plain text notes or a photo of a page, and get questions based on what you actually need to learn.

Explanations on every answer

Each multiple-choice, true/false and short answer question comes with an explanation, so wrong answers teach you something.

Export when you need it

Paid plans export to PDF, DOCX, Anki and CSV. Pro adds QTI 2.1 and Moodle XML for classes that run on an LMS.

How it works

Study or export

Work through the quiz in your browser, or export it if you are on a paid plan.

What DeckOwl does is generate a quiz from your own course material. Free accounts get 3 generations a month and study in the browser. Plus costs $39/year or $7.99/month for unlimited generations and PDF, DOCX, Anki and CSV export. Pro costs $14.99/month and adds a stronger AI model, bulk upload, and QTI 2.1 and Moodle XML export.

If you have a school email, students get 40% off, and you can start without a credit card. Upload the notes from your next lesson and compare the questions it writes with the ones you would have written yourself.

Frequently asked questions

How often should I quiz myself on new material?

Quiz yourself within a day of the lesson, then again after a few days and once more before the test. Short sessions spaced across the week work better than one long cram.

How do I know if a practice quiz is working?

If you can answer a question without looking at your notes and can explain why the wrong options are wrong, the material is sticking. Missed questions show you what to review next.

Can I host a live game with a join code in DeckOwl?

No. DeckOwl does not run live games or assign join codes. It generates quizzes you study on your own, and paid plans can export them.

Which export formats are included in each plan?

The free plan has no exports. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML.
