�� About Us

ROOTED is an emotional support app designed to help people navigate everyday emotional challenges through real-time, AI-powered conversations. Built by a cross-disciplinary team of psychologists, technologists and creatives, ROOTED offers a deeply personal and intuitive mental well-being experience — not just as a tool, but as a companion.

We’ve launched our web version, and now we’re bringing the experience to mobile, starting with React Native (iOS-first).

At the heart of ROOTED is RuMa (Running Mammals) – our proprietary conversational AI, built using cutting-edge LLMs, designed to reflect and respond to human emotion with empathy and insight.
