Recent advances in crowdsourcing have led to new forms of assistive technologies commonly referred to as crowdpowered devices. To best serve the user these technologies crowdsource human intelligence as needed when automated methods alone are insufficient. In this paper we provide an overview of how these systems work and how they can be used to enhance technological interventions for positive psychology. As a specific example we describe previous work that crowdsources positive reappraisals providing users timely and personalized suggestions for ways to reconstrue stressful thoughts and situations. We then describe how this approach could be extended for use with other positive psychological interventions. Finally we outline future directions for crowd-powered positive psychological interventions.
