The document describes a proposed app called "Build Your Own Dictionary" that would help users learn new words in different languages. The app would allow users to take photos of items with QR codes that would then display the word's definition in both English and Spanish. It would be used primarily by students but also others looking to learn a second language. The document discusses how the app would work, addressing questions about how it would help people learn languages and what would happen if someone tried to damage the app. It also covers how the app would store user information and provide feedback.
