FlashHack turns any document or photo of notes into a smart study deck — instantly. Point your camera at a page of handwritten notes, upload a PDF, or snap a photo of a textbook chapter. FlashHack uses AI to read the content and generate high-quality flashcards in seconds. Edit, delete, or add cards to fine-tune your deck before studying. Once your deck is ready, study with spaced repetition (SM-2 algorithm) that schedules reviews based on how well you know each card — so hard cards come back sooner and easy cards fade into the background. Rate each card as Again, Hard, Good, or Easy, and FlashHack handles the rest. Not sure about something? Open Chat Q&A and ask any question about your document. The AI answers based on your uploaded content, so you get relevant, focused answers instead of generic web search results. What you can do in FlashHack: • Scan handwritten notes or printed pages with your camera • Upload PDF documents or images from your gallery • AI instantly generates 10–30 smart flashcards per document • Edit, reorder, add, or delete cards to personalize your deck • Study with flip-card UI and spaced repetition scheduling • Rate each card: Again / Hard / Good / Easy • Track mastered cards and study progress per deck • Chat Q&A: ask AI questions about any deck's content • Chat history saved per deck for reference • Free tier: 3 deck generations per day with ads • Premium: unlimited generations, ad-free, priority AI Subscription automatically renews unless canceled at least 24 hours before the end of the current period. Payment is charged to your Apple ID account at confirmation of purchase. You can manage and cancel subscriptions in your App Store account settings.
