The Mathia project, winner of the P2IA (Partnership for Artificial Intelligence Innovation of the Ministry of National Education), aims to create an innovative solution based on artificial intelligence for mastering the fundamentals of mathematics (discovery and training). Mathia is a unique combination of voice recognition and 3D visualization applied to mathematics; the application and platform are used in partner classes and allow children to play with mathematics through numerous application exercises. On the other hand, Mathia allows the teacher to track the progress of each of his students.
