​The app breaks down complex AI concepts into more straightforward notions making them accessible to a broad spectrum of young users. Via the interaction with SMAILEApp, the learners can understand AI concepts in depth. This deep knowledge allow the students not only to become responsible users of AI technology but also, and crucially, to create AI tools and apply them across different disciplines. SMAILEApp’s objective is to switch the perception of AI from a black-box, obscure technology used by everyone but known only by an elite to a powerful instrument that the young people can leverage to unleash their creativity and build useful activities and artefacts. SMAILEApp starts from simplified real-world problems that would benefit from an AI solution and assists the students in gradually construct the required building blocks to design and implement such a solution. This approach will not only make learning more exciting but will also convey the fundamental idea that AI is a multi-disciplinary field in which many competencies are needed to succeed.
