About
Greenside AI is an AI-powered golf swing coaching app for iPhone that brings professional-level swing analysis to everyday golfers. Using a patent-pending, 100% vision-based system, the app performs a comprehensive 13-point biomechanical breakdown of your golf swing—analyzing shoulder plane, hip rotation, stance alignment, swing path, and impact position—within seconds of recording or uploading a video. The AI engine is trained on a hand-curated dataset of over 500,000 golf swing images and has processed more than 15 million real-world swings. It leverages the iPhone's GPU and Neural Engine to deliver fast, accurate analysis anywhere—on the range, course, or simulator—with no internet connection required. Beyond measurement, Greenside AI uses predictive modeling to prescribe specific, actionable drills tailored to each golfer's unique biomechanics and swing tendencies, informed by insights from professional golfers and instructors. The app tracks swing metrics across sessions, showing how mechanics evolve over time and helping users spot patterns and sustain long-term improvement. Greenside AI also offers specialized plans for golf facilities and instructors who want to integrate AI-powered coaching into their operations. Trusted by PGA Tour professionals—including Players Championship winner Fred Funk—and everyday golfers across the country, the app has helped users fix slices, gain driving distance, hit more greens in regulation, and reduce handicaps. It is rated 4.9 stars and designed to make high-tech coaching accessible to all golfers.
