What is Vi Trainer?
What is Vi Trainer?
Vi Trainer is an AI-powered running coach that provides real-time audio coaching during runs, personalized training plans, and post-run performance analytics. Delivered through smart earbuds that monitor heart rate and biometrics in real time, Vi coaches runners through workouts using natural conversational voice guidance.
Real-Time Voice Coaching
Vi's differentiating feature is its real-time audio coaching during runs. Rather than following a static plan on a screen, runners receive spoken coaching cues — pace adjustments, encouragement, interval start/stop calls — based on live biometric data from the earbuds. This hands-free, heads-up coaching makes it feel closer to running with a human coach than any screen-based app.
