DeA Link - Interactive Textbook Platform

Project Overview

SweetSoft developed DeA Link, a mobile application for De Agostini Scuola, a leading Italian educational publisher. The solution enables schoolchildren to quickly access multimedia content directly from textbook pages, transforming traditional printed materials into interactive learning tools. Students can photograph book pages or select from a catalog, frame specific content, and instantly access embedded videos, audio, animations, galleries, and exercises, seamlessly bridging the gap from paper to digital learning.

Client Impact

DeA Link has revolutionized how De Agostini Scuola delivers educational content to Italian schoolchildren, transforming traditional textbooks into dynamic, interactive learning experiences. The application has bridged the gap between physical and digital learning materials, allowing students to instantly access rich multimedia content simply by photographing textbook pages. The intuitive interface designed specifically for young users has made advanced technology accessible to schoolchildren of all technical abilities, while the offline viewing capabilities have ensured continuous learning regardless of internet connectivity. The support for multiple content types—videos, audio, animations, galleries, and interactive exercises—has enriched the learning experience beyond what printed materials alone can provide. The 80,000+ hours of development have created a robust, scalable platform that has positioned De Agostini Scuola at the forefront of educational innovation in Italy, demonstrating how traditional publishers can successfully embrace digital transformation while enhancing rather than replacing their core printed materials. The seamless “paper to digital” experience has made learning more engaging and interactive for thousands of Italian students.
