Open source options and what DeckOwl offers

If you want an open source AI quiz generator, start by checking the license and whether you can run the code yourself. DeckOwl is not one of those projects. It is a hosted tool, so you work in the browser and do not install or maintain anything.

Example open source licensing quiz questions

What does the MIT license allow users to do with the code?It allows use, modification and redistribution, including in proprietary products, as long as the license and copyright notice are kept. Why: it is a permissive license with few conditions.

What is copyleft?A licensing approach where distributed modified versions must be released under the same license terms, as with the GPL. Why: it keeps derivative works open.

What does the Open Source Initiative publish?The Open Source Definition, along with a list of licenses that meet it. Why: it gives a shared test for what counts as open source.

Which license requires modified versions you distribute to share their source code: MIT or GPL?GPL. It is copyleft, so distributed modifications must be released under GPL terms. Why: MIT has no such requirement.

What is a fork in open source development?A new project started from a copy of an existing codebase that can then develop independently. Why: open licenses permit copying, so forks happen when maintainers disagree.

Study or export

Answer in the browser on the free plan. Export is available on paid plans.

DeckOwl is built for students who already have their own material and want practice questions from it. The free plan includes 3 generations per month with browser study. Plus, at $39 per year or $7.99 per month, removes the generation limit and adds PDF, DOCX, Anki and CSV export.

For the open source topic itself, a quiz helps you tell apart licenses that look similar, such as permissive and copyleft terms. Generating questions from your course readings and checking the explanations is a practical way to review them.

Frequently asked questions

Is DeckOwl an open source project?

No. DeckOwl is a hosted web app, so you use it in the browser rather than running its source code yourself. Exports to PDF, DOCX, Anki, CSV, QTI and Moodle XML require a paid plan.

What is the difference between open source and source-available licenses?

Open source licenses, such as MIT and GPL, let people use, modify and redistribute code under the license terms. Source-available licenses let you read the code but often restrict copying or reuse.

How should I study open source licenses for an exam?

Compare permissive licenses like MIT and Apache 2.0 with copyleft licenses like GPL, focusing on what each requires when you redistribute code. Then quiz yourself on one comparison at a time.

Can I export a quiz to Moodle?

Moodle XML export is available on the Pro plan at $14.99 per month. The free plan supports browser study only, and Plus adds PDF and DOCX export.
