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. Material you know can return after a longer interval, alongside the content that needs more practice. A FRESH LOOK TO HELP YOU FOCUS Version 4.0 redesigns Home, Library, Settings and the study screens, making it easier to start today’s review or continue an unfinished session. Find materials with search and folders, and look back at your study history. Review 3 pages per session by default, or choose 1–10 to suit the time you have. You can also select materials yourself and study them again. SHARE MATERIALS THAT ARE READY TO STUDY Send editable, masked study sheets to friends. Save materials, masks and study history in a backup file and restore them when needed. Sending requires the paid upgrade; receiving is available in the free version. No ads. Complete your first study session to unlock storage for up to 10 pages. A one-time paid upgrade removes the storage limit and unlocks additional paid features. Recognition and masking results vary with your photos and materials. Check and edit them when needed.
