Persuasive systems play a crucial role in supporting and counseling people to achieve individual behavior change goals. Intelligent systems have been used for inducing a positive adjustment of attitudes and routines in scenarios such as physiotherapy exercises, medication adherence, smoking cessation, nutrition & diet changes, physical activity, etc. Beyond the specialization and effectiveness provided by these systems on individual scenarios, we provide a vision for collaborative creativity based on the multi-agent systems paradigm. Considering novelty and usefulness as fundamental dimensions of a creative persuasive strategy, we identify the challenges and opportunities of modeling and orchestrating intelligent agents to collaboratively engage in exploratory and transformational creativity interactions. Moreover, we identify the foundations, outline a road-map for this novel research line, and elaborate on the potential impact and real-life applications.
