The Platform
Pro-level biomechanics. Built for individuals.
Every metric the pro scouts and sports scientists use, now available to any athlete with a phone and a video clip.
3D Skeleton Overlay
33-point MediaPipe landmark tracking rendered in real-time 3D. Full joint angle extraction across every frame of your video — shoulders, elbows, hips, knees, and ankles.
Jump & Vertical Analytics
Parabolic trajectory modeling with Rapier.js physics validation — measures hang time, peak vertical height in inches, takeoff velocity, and RSI-Modified score.
ACL Injury Risk
Knee valgus angle tracking with color-coded risk scoring on every landing. Flags dangerous mechanics before they result in injury — frame-by-frame precision.
Ghost Mode
Your movement overlaid against a matched pro athlete. Powered by pgvector similarity search — finds the closest professional match to your position, body type, and jump signature.
Kinetic Chain Analysis
Full-body power transfer analysis. Peak force in Newtons, ground reaction, relative power output in W/kg, and vertical impulse in Newton-seconds — the same metrics sports labs use.
AI Coach — VERA
Your personal volleyball performance advisor. VERA synthesizes every metric from your sessions into actionable coaching cues, prioritized by impact and specific to your position.
Recruit-Ready Profile
A shareable, data-backed athlete profile built from your biomechanics sessions. Jump height, arm speed, agility scores, and video clips — formatted for college coaches and recruiters.
Film Room
Upload game and practice film for deep review. Tag clips, annotate plays, and generate highlight reels automatically. Your film library, organized and analyzed.
5-10-5 Agility Testing
Lateral closing speed and the shuttle drill analyzed from standard video. No force plates or specialized equipment required — just your phone and court footage.
How It Works
From video to data in under 2 minutes.
No wearables. No lab. No coach required. Just upload your footage and the platform does the rest.
01
Upload Your Video
Upload any video from your phone, camera, or cloud — practice, game film, or a dedicated session. 4K supported. No special angle or setup required.
02
AI Processes Every Frame
Our ONNX-powered inference engine runs MediaPipe pose estimation on every frame at up to 15fps. WebGPU acceleration when available — WASM fallback otherwise.
03
Biomechanics Are Extracted
A dual-stage Kalman filter smooths pose data. The BiomechEngine calculates joint angles, kinetic chain metrics, jump physics, ACL risk, and arm speed — all from pixel data.
04
Get Your Report
Receive a complete biomechanics report with 3D visualization, position-specific benchmarks, injury risk flags, VERA coaching cues, and a sharable PDF — all in your session library.
Positions
Built for every role on the court.
Every metric, benchmark, and coaching cue is calibrated to your specific position — not generic athlete data.
Hitter / Outside
Arm speed, approach mechanics, jump timing, and attack angle analysis.
Setter
Hand positioning, set trajectory, tell-pattern detection, and footwork analysis.
Libero
Lateral speed, defensive positioning, passing platform angle, and dive mechanics.
Middle Blocker
Block timing, explosive lateral step, quick attack approach, and net contact detection.
