AI Study Assistant: Notes to Quizzes & Flashcards
Shater is your AI-powered study assistant that transforms your notes, PDFs, and images into instant quizzes, summaries, and flashcards.
In plain English
Shater, a phone app from Abdulrahman, turns notes, saved documents, and photos into quizzes, summaries, and flashcards. A class can share a quiz, which helps teachers as well as students who want practice from pages they already have. People subscribe when they want to keep going without a cap on use. Abdulrahman reaches them through teachers and through search in the phone store. The AI does most of the quiz making and the billing, while Abdulrahman keeps improving the app, answers users, and watches for odd cases.
