No expensive sensors. No account required. Import any video from your library and get frame-by-frame biomechanical feedback.
– WHY ATHLETES & COACHES CHOOSE AXIFY –
◆ See the Invisible
Don't just watch a slow-motion video. AXIFY's AI automatically detects your skeleton and measures the exact degrees of your elbow, knee, hip, and shoulder joints at every frame.
◆ Track Real Progress
Stop relying on "it feels better." AXIFY records your joint angles over time, creating visual charts that prove your mechanics are actually improving week over week.
◆ Total Privacy (100% On-Device AI)
AXIFY uses Apple's Vision framework to process everything locally. AI analysis happens entirely on your device. Your videos are never uploaded, and you don't even need an account to start.
◆ Coach from Anywhere
Export your videos with the skeleton and angle data burned directly into the footage. Add voice memos, draw custom lines, and share the exact moment of breakdown with your students or coach.
