About QAI
Last updated：2026-08-21
QAI is a free tool that uses AI to write practice questions and mock exam papers, mainly for students preparing for Taiwan’s entrance examinations and for their teachers.
What it is
Give it a topic, a passage, a handout, a YouTube link or a web page, and it writes multiple-choice questions with full explanations. The exam zone produces whole mock papers calibrated to the syllabus scope, question style and difficulty of Taiwan’s CAP, GSAT, AST and VTE examinations.
Questions you get wrong are scheduled for review and come back around the time you would otherwise have forgotten them.
Who makes it
QAI is an independent project. There is no company behind it and no investor. It is currently maintained by one person.
Questions, suggestions, or a wrong question you spotted — write to willson114478@gmail.com. I read it myself.
The principles behind it
- Testing beats re-reading. Re-reading makes material feel familiar, and familiarity is not recall. So QAI writes questions, not notes or summaries.
- When you review matters more than how often. Reviewing just before you would have forgotten is what works, so the schedule is built around that rather than around drilling the same set daily.
- No engagement mechanics. No leaderboards, no punishment for breaking a streak, nothing that exists to keep you here five more minutes. Exam candidates are short of time already.
- Nothing unevidenced. Learning-styles quizzes, for instance, are not supported by the research, so we do not ship one however well it would share.
- Students answer without an account. A paper a teacher shares opens and works on any device. Requiring a whole class to register with a third-party service to sit one quiz is not a reasonable ask.
- No behavioural advertising to minors. Our users start at junior high, so advertising is set to non-personalised and does not profile behaviour.
Common questions
Can the questions be wrong?
Yes. Several automated audits run — answers are independently re-solved, items with no correct option or two defensible ones are deleted, distractors and visuals are checked — but no paper is guaranteed correct. The detail, including what the audits cannot catch, is on the accuracy page.
Does it cost anything?
No. It is free, supported by advertising. To bound the AI cost there is a limit of 3 generations per account per day, and up to 25 saved quizzes.
Why does generating require a sign-in?
Because each press spends real money. An account is what lets the free daily allowance be counted per person instead of being drained by whoever finds the site first. Answering a quiz someone shared with you needs no account at all.
Can teachers use it with a class?
Yes. When sharing, you can switch on result collection: students answer without registering, and the management key shows you who answered, the per-question success rate and the class average. Read §5 of the terms first — with it switched on, you are the party collecting that student data.
Do you use real past papers?
No. We neither reproduce nor host official papers. Everything generated is AI-authored in the style and scope of the exam. The past-papers section links out to the official sites only.
Where is my data kept?
In your account rather than in the browser, so it follows you across devices and deleting removes it everywhere. See the privacy policy.
