    Baba uses a fine-tuned large language model to hold conversations with older adults and analyze tone, sentiment shifts, and emotional cues. The system logs call summaries and risk flags for caregiver review and tracks changes over time.

Study Details

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.
