The SerenMind project is an intelligent assistant designed to mitigate the negative effects of excessive social media use among university students. It integrates empathetic AI, data analysis, and emotional management to foster a conscious and critical relationship with technology. Its structure is based on two complementary modules: "Mind Balance," which analyzes habits, generates reports, and allows for the selective blocking of distracting apps like TikTok and Instagram to increase productivity; and "Serene Voice," which uses voice commands to analyze screenshots in real time and verify news, offering calm responses with sources and unsensationalized summaries to stimulate critical thinking. The project's success will be measured using digital wellbeing indicators and the increase in critical thinking, with an ethical focus on privacy during its implementation and validation in educational settings.
