About the study

Baba is a novel AI "care copilot" designed to improve emotional well-being, cognitive stimulation, and social connection through emotionally present conversations, proactive engagement, and personalized communication. Unlike many existing solutions, Baba operates through SMS text and voice calls, requiring no apps, Wi-Fi, or new devices, making it particularly accessible to older adults.
