Turn your own notes into a Gimkit-style quiz app

DeckOwl is not a live multiplayer game. It reads your own PDFs, slides, notes or photos of pages and builds quiz questions with explanations you can study now.

Gimkit-style quizzes built from your own material

Students and teachers who search for a gimkit app usually want one thing: a fast way to turn review material into questions people can answer and check.

  • Questions come from your own files, so the content matches your course.
  • Each question includes an explanation, which helps more than a bare right or wrong mark.
  • Multiple-choice, true/false and short answer formats are all available.
  • No credit card is needed to start, and students get 40% off with a school email.
Example acids and bases quiz questions
What is the pH of a neutral solution at 25°C?7. Pure water has equal hydrogen and hydroxide ion concentrations, so neither dominates.
Is a solution with pH 3 acidic or basic?Acidic. Values below 7 mean a higher hydrogen ion concentration than hydroxide ion concentration.
What is the conjugate base of HCl?Cl⁻. Removing the proton from HCl leaves chloride ion.
True or false: a strong acid fully dissociates in water.True. Strong acids such as HCl ionize almost completely, so the reaction goes essentially to completion.
What does a buffer do when a small amount of acid is added?It resists a pH change because its weak acid and conjugate base pair consumes the added hydrogen ions.

Quizzes from your material

Upload a PDF, DOCX, PPTX, text file or photo of a page. Get multiple-choice, true/false and short answer questions with explanations.

Flashcards and mind maps too

The same upload can produce flashcards with spaced repetition and mind maps, so you can review the material in more than one format.

Export when you need it

Study in the browser on the free plan. Plus adds PDF, DOCX, Anki and CSV export. Pro adds QTI 2.1 and Moodle XML for course platforms.

How it works

Upload your material

Add a PDF, slides, a DOCX file, plain notes or a photo of a textbook page.

Choose a question type

Pick multiple-choice, true/false or short answer, or generate a mix of all three.

Study or export

Work through the quiz in your browser, review the explanations, and export if you are on a paid plan.

DeckOwl reads PDF, DOCX, PPTX, plain text and photos of pages with text recognition, then generates multiple-choice, true/false and short answer questions with explanations. The free plan includes 3 generations per month and browser study. Plus, at $39/year or $7.99/month, gives unlimited generations and PDF, DOCX, Anki and CSV export. Pro, at $14.99/month, adds a stronger AI model, bulk upload, and QTI 2.1 and Moodle XML export.

If you need a live game with a shared leaderboard, DeckOwl is not that. It is built for creating the question set from your own notes so you can practice alone or export it into another tool.

Frequently asked questions

How do I write good quiz questions for acids and bases?

Focus on one idea per question, such as identifying conjugate pairs or predicting whether a solution is acidic from its pH. Avoid questions that can be answered by guessing between two similar terms.

How many practice questions should I do on acid-base chemistry?

Start with about 15 to 20 questions across pH, strong and weak acids, and buffers, then repeat the ones you missed. Spacing your practice over several days usually works better than one long session.

Can I export my quiz to Moodle?

Moodle XML export is available on the Pro plan at $14.99/month. Anki, PDF, DOCX and CSV export are included in Plus at $39/year or $7.99/month.

Is there a free way to try DeckOwl?

Yes. The free plan includes 3 generations per month and browser study, and no credit card is needed to start. Exports are not included on the free plan.
