YouUseAI is an online learning platform for children from age three through primary school. They learn through play, with 19 activities in Vietnamese and English: letters, counting, telling the time, money, the abacus, times tables, first coding and drawing. Every instruction is a picture and a spoken line, and parents get a panel showing what was practised. It opens in a browser tab, with no adverts and no account to create. For the grown-ups there are 3D games and small apps as well.
