You write the question sets
Sets are plain JSON or Lua files. The help pages walk through the format, and there is a prompt you can hand to an AI to draft one for you. A checker in the browser tells you whether a file is valid.
Your own questions, at your own pace.
Quiz App is a study tool that works through question sets you write yourself. It runs entirely in the browser — nothing to install, no account to create.

What it is
There are no questions in the box. You start by writing a question set and loading it. Certification drilling, revising a course, hammering vocabulary — because you decide the content, the subject is up to you.
Who it is for
- People who want to write their own questions and drill them repeatedly
- People who learn by being asked, not by re-reading notes
- People who want a record of their study and a view of their weak spots
What it does
Questions adapt to your answers
Endless mode estimates how well you know the material from your answer history and picks the next question accordingly, so you are not stuck on what you already know or shown the same item twice in a row.
A record you can actually read
Every session records when you studied, how many questions you answered and how long each took. Beyond a percentage, you can see where your confidence and your results disagree, and how each tag is holding up (beta).
Formatting inside questions
Bold, colour, links and icons can be used in question text, choices and explanations — useful when plain text is not enough to make the point.
Four modes
The same question set, approached in whichever way fits what you are doing.
Linear
Work through the set in file order, start to finish. Good for reviewing a set you have just written.
Endless
Keep going with no fixed end. The next question is chosen from your answer history, so weak areas come up more often on their own.
Mock exam
Fix a question count and a time limit and sit it like the real thing. The order changes every attempt.
Review
Redo only the questions you got wrong. You can take them from one session, or collect everything still marked wrong across the whole set.

About your data
The question sets you load and the answers you give are stored inside your own browser. Nothing is sent to a server, and there are no accounts.
- This site and the app count page views without cookies. Nothing about what you study is included.
- Clearing your browser data also clears your sets and history, so keep your own copy of any question set that matters.
