BIOMECHANICAL INSIGHTS & TRAINING OPTIMIZATION
AI-powered movement analysis for every level of the game. Data-driven insights to support informed training decisions.
VIDEO UPLOAD
Upload any pitching video — bullpen sessions, game film, or practice footage. MP4, MOV, and AVI supported up to 50MB.
POSE DETECTION
MediaPipe AI tracks 33 body landmarks frame-by-frame. Shoulder, elbow, and wrist angles calculated from pose estimation data.
ANGLE ANALYSIS
Elbow layback angle during max external rotation. A key biomechanical factor associated with UCL stress and elbow injury patterns.
RISK SCORING
0-100 risk score based on biomechanical thresholds from peer-reviewed research. Scores are probabilistic estimates and should be interpreted alongside professional expertise.
FLAG DETECTION
Automated screening for common high-risk movement patterns including excessive layback, arm drag, and trunk rotation timing. Not all risk factors can be detected from video alone.
PRIVACY FIRST
Video never leaves your browser. All analysis runs locally via WebAssembly. No uploads, no cloud storage, no third-party access.
SEE WHAT YOU GET
Every analysis delivers a detailed AI-powered biomechanical report. Here's what you receive with each assessment.

FREQUENTLY ASKED QUESTIONS
Everything you need to know about ThrowCheck.
Our biomechanical models analyze pitcher mechanics using pose estimation technology and compare measurements against published sports medicine research thresholds. While no analysis system is perfect, our risk assessments provide data-driven insights based on peer-reviewed biomechanical studies that complement traditional scouting evaluation.
No. ThrowCheck is an informational and analytical tool only. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider for medical decisions.
Yes. Cancel anytime through your account dashboard. No contracts, no cancellation fees. Your access continues through the end of your billing period.
We analyze publicly available pitching data including velocity, spin rate, pitch movement, workload history, and injury records. Video analysis uses AI-powered biomechanical modeling to assess mechanics.
Fantasy baseball players who want to avoid drafting injury-prone pitchers. Coaches evaluating pitcher durability. Scouts analyzing prospect risk profiles. Baseball fans who want deeper insight into pitcher health.
Most analytics tools focus on performance metrics. We focus specifically on injury risk and durability — the one thing that can make all other stats irrelevant. A pitcher's best ability is availability.
