CoachAI — Your Private, On-Device Tennis Coach CoachAI brings intelligent tennis coaching to every player and every court. Powered by on-device AI, CoachAI analyzes your technique without sending your tennis footage to a cloud AI service. Real-Time Stroke Analysis Receive feedback on your forehand, backhand, serve, volleys, and other strokes. CoachAI evaluates technique, timing, movement, and consistency as you practice. Recorded-Video Analysis Choose a tennis video from your Photos library and receive structured coaching feedback, including strengths, technique observations, a priority correction, and a recommended drill. Footwork & Movement Tracking Review positioning, balance, preparation, swing mechanics, contact, follow-through, and recovery to understand where your movement can improve. Private, On-Device AI Camera frames, selected videos, sampled frames, prompts, and coaching results are processed locally on your device. They are not uploaded or sent to OpenAI, Google, Hugging Face, or any other third-party AI service. CoachAI’s built-in FastVLM model works offline. An optional higher-capability FastVLM model pack can be downloaded through Apple-hosted Background Assets. This download contains only model files—your photos, videos, prompts, and results are never included or uploaded. Progress Over Time Track your development from session to session and see your technique improve across lessons and practice activities. Whether you’re learning the fundamentals or refining your game, CoachAI provides private, practical feedback that adapts to your training. Step on the court. Practice smarter.
