Students work through curriculum topics per subject — biology, Dutch, English maths, and so on - and get a personal AI tutor for each topic that answers questions and guides them through the material. As they go, they make exercises that are automatically assessed (open and multiple‑choice), tagged against real didactic metadata like Bloom levels, learning objectives and difficulty. Schools, teachers and content sit behind it, with an admin panel for managing curriculum content.
