Napkin is an iOS app designed to help users collect and reflect on ideas. Users can add text from other apps, scan from books, dictate, or type directly. The app organizes ideas around topics automatically without requiring manual tagging or folders. A personal AI suggests topics for reflection based on the user's collected ideas. The app aims to provide a calm space for introspection and to increase a sense of coherence. The company is independent and based in Switzerland, with all servers in Europe and encrypted databases. Napkin is currently available for iPhone, with a desktop prototype also accessible online.
