Meta · Supernatural
Supernatural is one of the most immersive VR fitness experiences on Meta Quest. But something was missing: an AI presence that makes athletes feel genuinely supported, coaches them in real time and gets them into their workout faster. Meta engaged Astral City to build it. The Fitness Companion made onboarding faster, setup simpler and in-workout coaching more accurate — from the moment you speak to the moment you move.
Supernatural had the workout. The silence around it needed a voice.
Supernatural already had AI-enabled coaches: high-energy video guides who talk athletes through every move. The brief was not to replace them — it was to fill the gaps they couldn't reach. Three jobs mattered most: making athletes feel less alone, removing the 'am I even doing this right?' question, and guiding what to do next. Meta engaged Astral City to build an AI that could earn an athlete's trust and improve the quality of every workout.
A Companion designed to train alongside you, not talk at you.
We built a Conversational AI Companion that lives across the full arc of the workout: before you start, during your session and after you finish. Context-aware, personality-led and integrated directly into the Supernatural VR environment on Meta Quest. The Companion was designed around five principles: real-time feedback tied to actual session performance, context-aware coaching using the athlete's history and goals, a persona built to earn trust progressively, a multimodal presence that felt natural inside VR, and real-time movement responsiveness.
Built around six traits: adaptive tone, data-customised responses, context-aware coaching, RAG-supported knowledge, multimodal presence and a clear understanding of its own limits. A training partner athletes trusted to tell them the truth.
A Unity-built VR integration on Meta Quest with real-time movement responsiveness: the Companion reads what the athlete is doing and responds with accurate, in-the-moment coaching feedback. Voice and visual state transitions capped at 350ms.
High-energy coaches active during gameplay; the Companion active across the session lifecycle — before, during, and after. Both layers designed to build athlete confidence and improve workout quality simultaneously.
An 11-beat conversational flow replaced menu-heavy setup with natural dialogue, collecting personalisation data while cutting the time from app open to first workout. When people describe their goals in their own words, the AI has better data and the user has better motivation.
"We built the AI that gets you into your first workout faster, then stays with you, responding to your actual movements in real time."
Faster setup, better feedback, deeper trust.
The most significant outcome was the real-time responsiveness test: the Companion could respond to athlete movement during gameplay, delivering accurate, in-the-moment coaching that improved workout quality. The onboarding system cut the time from app open to first workout. Athletes felt more confident and supported across the full session.
Most AI talks at people. This one listened first. Conversational AI in immersive fitness is not a chatbot layer — it is a coaching relationship built on accuracy, trust and personalisation. The question is not whether an AI can respond, but whether it can adapt to what an athlete is actually doing, remember their history, and make them feel genuinely supported throughout.
