Hi Product Hunt! I'm Satwik, and Cerebo is my hobby project. I built it because my flashcards kept outgrowing the card: equations, code, graphs. Most flashcard apps give you two text boxes. In Cerebo a card is a stack of blocks: text, math, code, tables, a plotted function or a 3D surface you can rotate, images, audio, even a PDF. Spaced repetition (SM-2) decides when you see each one. Version 1.1 just came out, and it's the part I'm proudest of. On iPhones and iPads with Apple Intelligence, everything AI runs on the device with Apple's Foundation Models, so nothing you study leaves your phone: • Attach a PDF or a photo of your notes, or record a lecture, and the chat drafts a deck you review card by card before anything is added • Ask questions and see which of your cards the answer came from • Get quizzed on a deck, typed or out loud • Tap Test on any deck for a practice test: the model writes near-miss wrong options and checks written answers for meaning. Every iPhone and iPad also gets a timed Match game It's free: no ads, no subscription, no account, and no data collected. It imports Anki (.apkg) decks and Quizlet sets, syncs through your own iCloud, puts your library in a sidebar on iPad and the new iPhone Duo, and has an Apple Watch app. What subject would you try it with first? And what would you need before switching from the app you use now?
