Turn the materials you already study into hide-and-reveal practice. AI Study Sheet hides key terms in photos and PDFs, helping you recall what you learned in class, a course or workplace training. Keep the original page layout instead of retyping everything into flashcards. FROM CLASS NOTES TO CERTIFICATION STUDY Import textbook pages, class handouts, lecture notes and course PDFs. Review vocabulary, definitions, dates and key concepts for quizzes, midterms, finals or certification exams. Use it alongside school, college, tutoring and professional courses for the memorization part of learning. LESS SETUP, FEWER TAPS AI selects key terms to hide while preserving the text, diagrams and layout around them. Check and edit the masks whenever you need to. In Auto mode, the highlighted mask opens after 3 seconds to reveal the answer. Try to recall it before it appears. Prefer your own pace? Use Manual mode to reveal answers yourself. REVIEW BASED ON WHAT YOU REMEMBER After studying, record whether you remembered each page, felt unsure or need more practice. Your ratings and study activity help the app recommend what to review next. Enable notifications to open Auto study directly when review material is available. Choose 1–10 pages per session and resume an interrupted session from where you left off. ORGANIZE, SHARE AND BACK UP Find materials with search and folders, and look back at your study history. Share editable masked materials so someone else can study them too. Back up materials, masks and study history to a file and restore them when needed. PRIVATE STUDY ON YOUR DEVICE Our custom AI masking runs entirely on your device. Study with confidence without sending your materials or OCR text to external servers. OPTIONAL STUDYPLUS INTEGRATION After connecting to Studyplus and giving consent, your study duration, session end time and a generic comment can be recorded automatically when each new study session ends. You can turn automatic recording off at any time in Settings. FREE TO START, ONE-TIME UPGRADE No ads. Save up to 3 pages at first, then up to 10 after completing your first study session. The optional one-time upgrade removes the save limit and lets you send shared materials. Free users can receive shared materials within their save limit. Purchase restoration is supported.
