Noji is a flashcards app aimed at exam preparation across subjects such as anatomy, biology, SAT, GRE, and medical board exams. It lets users import and transform material from services like Quizlet, Anki, Knowt, and Gauth into custom decks, including image‑occlusion cards for detailed visual study. The app reviews cards using a spaced‑repetition algorithm with options for Again, Hard, Good, and Easy, and it offers pronunciation playback for English vocabulary generated via ChatGPT. Decks created on a PC or tablet synchronize to a phone, providing a unified, simple‑UI environment for active recall.
