Add your materials. Get support for the whole study routine. Choosing terms to hide, finding the next page to review, tapping to uncover every answer: the small tasks can get in the way of studying. AI Study Sheet helps take care of them. Add photos of your textbooks, worksheets or notes, or import a PDF. AI masks key terms, the app picks pages for review, reminders bring you back, and Auto reveals answers for you. GET STARTED WITH A PHOTO OR PDF AI finds key terms and hides them for practice, without making you mask each one by hand. Text and diagrams stay on the original page. You can edit the masks when needed and use materials you have already prepared for hide-and-reveal study. ANSWERS APPEAR IN 3 SECONDS In Auto mode, the highlighted answer is revealed after 3 seconds. Focus on recalling it instead of tapping through every mask. Prefer your own pace? Use Manual mode. A REMINDER THAT LEADS STRAIGHT TO REVIEW When pages are available to review, tap a reminder to start them in Auto mode. No need to search for the materials or choose a study mode each time. WHAT TO REVIEW NEXT? LEAVE IT TO THE APP Rate each page as remembered, unsure or not remembered. Your ratings and study activity help the app pick your next review pages.
