An NBC6 article spotlights Kai Koerber, a survivor of the 2018 Valentine’s Day shooting at Marjory Stoneman Douglas High School, and the remarkable strides he has been making since then. While numerous classmates confronted the event’s aftermath through avenues like gun control activism, political endeavors, or personal healing and studies, Koerber’s technological fervor led him down an unconventional route.
Harnessing AI for emotional support
Instead of traditional advocacy, Koerber, 23, introduced “Joy,” a smartphone application built around artificial intelligence.
The app’s main feature is to recommend short mindfulness practices to its users, basing suggestions on their current emotional state. This unique feature identifies emotions from voice tones, irrespective of language or choice of words.
Post the Parkland tragedy, while many sought legislative solutions, the often-underemphasized aspect was mental health recovery. Koerber himself faced the harrowing effects of post-traumatic stress disorder, a reality for many survivors.

Innovation at the University of California, Berkeley
Koerber’s academic journey led him to UC Berkeley, where he initiated a research team.
Their mission was to develop groundbreaking AI solutions catering to real-time emotional needs, breaking the traditional confines of mindfulness practices.
An experience that stands out
The voice-emotion recognition feature of Joy is a noteworthy novelty, offering practices that can be adopted quickly in various settings.
Users simply speak into the app, and based on the detected mood, the app offers tailored activities. Although the AI might occasionally misinterpret a user’s mood, manual mood selection is available to rectify such situations.
Engaging activities and availability
From a short exercise to writing letters to one’s future self, the app offers diverse activities for various emotional states.
Priced at an $8 monthly fee with an annual discount, Joy continues to refine its AI capabilities with increased usage.

Experts weigh in
Dacher Keltner, a UC Berkeley professor, praises Koerber for his innovative use of technology in addressing mental and physical health crises.
He describes Koerber as a leader of the next generation who is thinking intentionally and with a focus on how to use technology to meet the mental, physical, and climate crises.
Colin Walsh, a professor of biomedical informatics at Vanderbilt University and an expert on AI’s use in suicide prevention, highlighted that the market is saturated with wellness apps claiming to aid mental health.
Walsh pointed out potential challenges: if a user feels the app’s interpretation does not align with their actual emotional state, a feedback mechanism should be in place for corrections.
On the topic of stakes, platforms like Facebook have been criticized for their AI-powered suicide prevention tools, which in grave instances, notify law enforcement about potentially suicidal users.
However, Walsh commented that if AI-driven interventions are benign, such as recommending users to spend time outdoors, the risks are minimal.
He also noted a surging demand, or at least the perception thereof, for wellness and mental health apps in recent times. Despite the current system’s commendable efforts, gaps remain.
Consequently, he believes many see technology as a means to bridge these gaps.
High stakes and survivor recovery
The long-term effects of trauma, especially from events like mass shootings, are profound.
Survivors often grapple with the aftermath for years, if not a lifetime. Koerber emphasizes that true recovery is a prolonged journey, unlike the rapid pace of the tech world.
Making a positive impact with technology
Koerbe’s approach to technology starkly contrasts with the fast-paced ethos of earlier tech giants.
Instead of rapid development, Koerber’s focus remains on creating meaningful products that prioritize social well-being.
His journey from a traumatic event to the creation of Joy encapsulates the potential of technology to support and enhance mental health recovery.
