What DeckOwl does and doesn't do for multiplayer quizzes

A multiplayer quiz maker usually means live games where a whole class answers on their own phones at once. DeckOwl works differently: it reads your material and writes the questions, then you practice them alone with explanations that show why each answer is right or wrong.

  • Multiple-choice, true/false and short answer questions drawn from your own material
  • An explanation for every answer, so wrong picks still teach something
  • Exports to PDF and DOCX on Plus, and QTI 2.1 and Moodle XML on Pro
  • Free plan: 3 generations per month, study in the browser, no exports
Example multiplayer networking quiz questions
What is latency in a multiplayer game?It is the delay between a player's action and the server's response, measured in milliseconds. It sets how responsive online play feels.
In client-server multiplayer, which side holds the authoritative game state?The server. It validates player actions, so clients cannot cheat by editing their own copy of the state.
What is client-side prediction?The client moves its own character immediately before the server confirms it, which hides latency. The server later corrects any mismatch through reconciliation.
Why do many real-time games use UDP instead of TCP for position updates?UDP avoids waiting to resend lost packets. Old position data is replaced by newer updates anyway, so resending it adds delay without helping.
What is tick rate on a multiplayer game server?It is how many times per second the server updates the game state. At 20 ticks per second, updates happen every 50 ms, and higher rates give smoother play at a higher CPU cost.

AI questions from your notes

Multiple-choice, true/false and open questions built from PDFs, slides, DOCX files and text.

Explanations on every question

Each answer comes with a reason, so reviewing a wrong pick teaches the concept behind it.

Exports for your class platform

PDF and DOCX on Plus; QTI 2.1 and Moodle XML on Pro, so questions can move into other tools.

How it works

Upload your material

Add a PDF, slide deck, DOCX file, notes or a photo of a page.

Choose question types

Pick multiple choice, true/false or short answer for the quiz.

Study or export

Answer in the browser on the free plan, or export to PDF, DOCX, QTI or Moodle XML on a paid plan.

The tool accepts PDFs, DOCX and PPTX files, plain notes, and photos of pages read with text recognition. Questions can be multiple choice, true/false or short answer, and paid plans export them to PDF, DOCX, Anki, CSV, QTI 2.1 and Moodle XML.

If your goal is live play, a tool built for real-time rooms will fit better. Many teachers use DeckOwl to build the question bank first, then bring it into their class platform through an export.

Frequently asked questions

What is latency in multiplayer games and why does it matter?

Latency is the delay between pressing a button and the server responding, usually measured in milliseconds. It matters because high latency makes movement and hits feel late, even when the game runs smoothly.

How should I study client-server architecture for an exam?

Trace one player action from the client to the server and back, then label where the game state is stored and checked. Explaining why the server holds authority is the part most exam questions test.

Does DeckOwl host live multiplayer quizzes?

No. DeckOwl generates quizzes from your material for solo study in the browser, and it does not run live rooms where players compete at the same time.

Which plan exports to QTI and Moodle XML?

The Pro plan at $14.99 per month includes QTI 2.1 and Moodle XML export. Plus, at $39 per year or $7.99 per month, includes PDF, DOCX, Anki and CSV export.
