How an AI quiz generator fits into studying

An AI quiz generator works best when it reads your own material, so the questions match what your class actually covers. Upload a PDF, slide deck, DOCX file, pasted notes or a photo of a page, and the quiz is built from that text, with explanations you can compare against the source.

Reads PDF, DOCX, PPTX, plain text and photos of pages
Every question includes an explanation for the correct answer
Free plan: 3 generations per month, studied in the browser
Plus and Pro add exports, including PDF, DOCX, Anki and CSV, with QTI 2.1 and Moodle XML on Pro

Frequently asked questions

How many quiz questions should I generate for one chapter?

Start with 10 to 20 questions per chapter so you cover the main ideas without rereading everything. Mix multiple choice with short answer, since producing an answer from memory builds stronger recall than picking one from a list.

Is taking a quiz better than rereading my notes?

Practice testing, where you try to answer before checking, generally improves retention more than rereading. Review the explanations for the questions you missed, then retake them after a day or two.

Can I export my quiz to Moodle or Word?

Yes, on paid plans: Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML. The Free plan lets you study in the browser without exports.

Do I need a credit card to try it?

No. You can start on the Free plan with 3 generations per month and no credit card.
