Turn the PDFs you already study from into quizzes that actually make it stick. Demonstratum takes your source (a chapter, a paper, your own lecture notes) and generates quiz questions from the exact pages you choose. Every answer cites the page it came from, so you can always check it against the original. Then you practice on a spaced-repetition schedule and build timed tests, until the material is genuinely yours. THE LOOP • Import: add any PDF to your library. Your sources stay organized like a shelf of books. • Generate: pick the pages that matter and let AI write the questions. It handles the busywork; you keep studying. • Check the source: every question links back to its page with one tap. No more wondering "wait, is that right?" • Review: practice in Learn, Review, or Cram mode. Spaced repetition brings each question back right when you're about to forget it. • Prove it: build timed tests that draw questions across all your quizzes, then watch your mastery grow on your study dashboard. WHY DEMONSTRATUM • Grounded in your material: questions come from your pages, not the open internet. • Cited answers: every explanation points to the source, so you can trust and verify it. • Real spaced repetition: an Anki-style schedule that adapts to how well you actually remember. • Timed tests: assemble exams across quizzes and simulate the real thing. • A daily launchpad: Today shows what's due, where you left off, and what to focus on next. • Clean and native: fast, distraction-free iOS design with light and dark mode. Built for students, exam prep, and anyone who learns from documents — lecture notes, textbooks, past papers, certification guides. Import your first PDF and see how much faster it sticks. DEMONSTRATUM PRO Pro is an auto-renewing subscription that unlocks unlimited quiz creation and editing. It is offered as a Weekly, Monthly, or Annual plan; the exact length and price of each plan are shown in the app before you buy, in your local currency.
