About Motion Coach
Motion Coach is a free, privacy-first AI personal trainer and automated workout tracking system that runs directly inside your web browser.
1. Mission & Vision
Motion Coach was built to solve a fundamental fitness challenge: getting instant, accurate form feedback without expensive personal trainers or privacy-invasive video uploads. Lift safer, hit proper depth, and prevent injuries directly from your browser.
2. Hybrid Privacy & AI Architecture
Camera feeds, pose landmark tracking, facial masking, and rep counting run locally inside your device browser. For deep form analysis, sanitized keyframe snapshots and anonymized pose telemetry are securely sent to Google Gemini AI in the cloud for biomechanical evaluation.
3. Deterministic Motion Tracking
Our motion tracking engine uses deterministic 3D pose landmark trigonometry to track 100+ exercises including squats, pushups, deadlifts, planks, and lunges. Get precise rep counting with zero guesswork.
4. Intelligent AI Form Coaching
Form corrections are analyzed using Google Gemini AI models to provide real-time audio and visual coaching on joint angles, spine alignment, and movement tempo.
