FlashHack: AI Flashcards

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.
