Sunny is a screen-free, AI-powered first companion that nurtures cognitive and language development from prenatal stages to age five. Grounded in cognitive and developmental psychology, Sunny delivers personalized, stage-based audio stories, songs, and rituals that strengthen phonological awareness, vocabulary growth, attention, and working memory. Children interact through natural motion and simple gestures, which trigger audio experiences and encourage multisensory learning without screens. The Elaves app enables caregivers to set preferences, choose languages, discover an educational content library, manage Sunny, and view progress insights. Sunny is made from child-safe silicone and features an ergonomic, durable design suitable for everyday play. It is engineered for reliable use at home and on the go, supporting routines like bonding, reading readiness, and calm transitions. Combining research-based methods with practical child needs, the Elaves ecosystem turns approved educational content and thoughtful hardware into playful, developmentally appropriate experiences during the most critical years of brain growth.
