Yes, and the quiz specifically is the mode that is never behind a paywall. Whatever plan you are on, a generated set can be sat, scored, and redrilled, which is the whole product for a lot of people. The Free plan hands you 2 generations for that, no credit card involved, and they are a one-off allowance for the account that does not top up each month. Free also covers 2 full sittings of each set it makes, and redrilling only the questions you got wrong falls outside that count, so fixing a mistake is free on every plan. Student and Genius stop counting sittings, so a set can be re-sat as often as it takes. When the 2 are gone, Student is $14.99 monthly for 100 generations, and Genius is $59.99 yearly under a fair-use ceiling of 1000 a month, with quizzes of up to 30 questions rather than 10.
PDFs, PowerPoint decks (.pptx), Word documents (.docx), plain text, Markdown, and CSV files, up to 10 MB each. Lecture slides, a chapter of a textbook, a past paper, or your own typed notes all work, and you can paste a link or paste the text in directly instead of uploading anything. GeniusPal scans the entire document rather than just the first page, so a long PDF still produces a quiz that covers the whole thing rather than the introduction. The one hard requirement is a real text layer. A scanned page or a photograph of handwriting carries no text for GeniusPal to read, and you get a clear message saying so rather than a quiz of invented questions. Older binary .ppt files need one re-save as .pptx first, which takes a few seconds and then uploads normally.
Each generation returns 10 multiple-choice questions on the Free plan, each with 4 answer options and the correct one marked. That is enough to give a topic a proper test without becoming a slog. A paid plan raises the ceiling to 30 questions per set, and a larger set is generated over proportionally more of your document, so the extra questions mean wider coverage rather than the same pages asked about twice. You can generate a fresh quiz from the same file whenever you want a new set, and on a paid plan the set you already have also runs as flashcards or as written active recall if you would rather review a different way. Re-sitting a quiz you already have, or redrilling only the questions you got wrong, costs no generation at all.
They are reliable for factual recall, and you should still treat the first quiz as a draft. Because the questions are built from your own upload rather than the open web, they stay closer to what you actually need to know than a generic quiz would, and where your material supports it a question shows the exact line it was drawn from so you can check it in one glance. Every set is also screened before you see it for the tells that let people score without knowing anything: an answer that gives itself away by being the longest, options that repeat each other, and "all of the above". Even so, skim the answer key before you study, fix anything that reads oddly, and delete any question that is trivially easy, so every question you revise from is one worth your time.
Yes, on a paid plan. A quiz is one of three ways to work through the same generated set. Flashcards flip the question and let you rate yourself, and active recall makes you write the answer out before you see it, which is the hardest of the three and the one that shows you most honestly what you do not know. You pick the mode when you open the set, so you never have to upload the same notes twice and switching between modes spends no further generation. The boundary is which plan you are on. Quiz runs on every plan including Free, while flashcards and written recall unlock with Student or Genius. There is also no export today, so a set is studied inside GeniusPal rather than sent to Anki or Quizlet, which is what lets it score you and bring back what you missed.
