Cognitus is an educational association active since 2018. Initially, they focused on topics related to psychophysical health and addiction prevention, while today they primarily specialize in preparing high school graduates for entrance exams at the Faculty of Medicine and the Faculty of Dental Medicine. To visually communicate their expertise and approachable character to young audiences, we developed a complete creative solution for them. Alongside a comprehensive visual identity, we also designed specific characters that appear in illustrations across the website and promotional materials. A large illustration library was also created for educational explainer videos.
