Every Tool a Coach
or Parent Needs

From pitch-count compliance to AI mechanics review — all in one app built for youth baseball.

PitchSmart Tracking

Automatically enforces MLB PitchSmart daily pitch limits and mandatory rest day rules based on your player's age. Never accidentally overtax a young arm again.

Injury Prevention
🔵
Illuminated Risk Score

A live 1–10 risk ring synthesizes weekly stress load, rest deficits, and mechanical data into a single, glanceable score. Green, yellow, or red — you'll know immediately.

Live Analytics
🤖
Claude AI Biomechanics

Upload photos or video frames. Claude's vision model analyzes arm drag, inverted-W, hyperextension, early trunk rotation, and low elbow — faults that cause UCL injuries.

AI-Powered
🎬
Slow-Motion Video Analysis

Load any video and scrub at 0.1× speed. Mark release point and plate contact to calculate exact pitch speed. Extract frames at any moment for AI review.

Video Tools
🏏
Swing Analyzer

Toggle to swing mode. AI detects casting, dropping hands, early extension, lunging, rolling over, and uppercut — the 6 faults that kill bat speed and power.

📄
Coach Conflict Card

Generate a professional PDF report showing pitch count limits and rest requirements for any date. Give it to coaches before games. No more conflicts, no more guesswork.

PDF Export
👥
Roster Management

Add multiple players with individual profiles. Each pitcher's age, throwing hand, and session history is tracked separately. Perfect for coaching staff with full rosters.

Team Ready
📊
Session History

Every session logged — bullpens, games, long toss, warmups. Track pitch type distributions over time to spot workload trends before they become problems.

Long-Term Tracking
Velocity Estimation

Two methods: AI estimates from mechanics and age, or measure precisely using video timestamps. Both shown side-by-side with a "MEASURED" badge when you have hard data.

Speed Analysis

Trained Eyes.
Every Frame.

Claude's vision model reviews your photos or video frames the same way a certified pitching coach would — except it's available at every practice, at every field, instantly.

Inverted W
Both elbows rise above shoulder height with forearms pointing down during arm cocking. Extremely high UCL stress loading.
HIGH
Arm Drag
Throwing arm lags behind body during acceleration. Forearm not vertical at foot strike, dramatically increasing elbow torque.
HIGH
Early Trunk Rotation
Upper body begins rotating toward home plate before front foot firmly plants. Reduces velocity and increases arm stress.
MEDIUM
Low Elbow
Slight elbow drop below shoulder height during cocking phase. Monitor and address in next session.

The AI caught an inverted-W in my son's delivery that three different coaches had missed for two years. We fixed it in six weeks. His velo went up and his elbow pain disappeared.

I print the Coach Conflict Card before every tournament. No more arguments with managers about pitch counts. The PDF has the official PitchSmart rules right there — it ends the conversation.

We run 8 teams in our organization. Having a single dashboard with every pitcher's risk score lets me see at a glance who's in the red before the weekend. Worth every penny of the Club plan.

Baseball Arm Injury
Prevention FAQ

How does ArmGuard AI prevent baseball arm injuries?

ArmGuard AI monitors pitch counts against PitchSmart guidelines, calculates a weekly stress load score, and uses AI vision to detect mechanical faults like arm drag and inverted-W that significantly increase UCL injury risk. When a pitcher approaches dangerous stress levels, coaches and parents receive immediate alerts — before an injury occurs.

What is a UCL injury and how is Tommy John surgery connected?

The ulnar collateral ligament (UCL) is the primary stabilizer of the elbow during throwing. Overuse and poor mechanics put repetitive stress on the UCL, leading to micro-tears and eventual rupture. Tommy John surgery reconstructs the torn ligament — but recovery takes 12–18 months. Studies show 73% of UCL injuries are preventable with proper pitch count monitoring and mechanics correction.

What are the PitchSmart pitch count limits by age?

PitchSmart is the official MLB and USA Baseball pitch count program. ArmGuard AI enforces these limits automatically:

Age Group Daily Limit Rest Days (≥66 pitches)
Ages 7–850 pitches3 days
Ages 9–1075 pitches3 days
Ages 11–1285 pitches3 days
Ages 13–1695 pitches4 days
Ages 17–18105 pitches4 days
What pitching mechanics cause arm injuries?

ArmGuard AI's AI vision engine detects these high-risk mechanical faults automatically:

  • Arm Drag — arm lags behind the body at foot strike, creating extreme UCL valgus stress
  • Inverted-W — elbows raised above shoulders during arm cocking, associated with elbow injuries
  • Early Trunk Rotation — rotating too soon reduces velocity and strains the elbow
  • Hyperextension — excessive elbow hyperextension during arm acceleration
  • Clean mechanics — proper arm path, layback, and follow-through are flagged as safe
Is ArmGuard AI suitable for youth baseball teams and clubs?

Yes. ArmGuard AI is designed for youth baseball pitchers ages 7–18 at every level — Little League, travel ball, high school, and club teams. The Team plan ($149/mo) covers a full roster, and the Club plan ($299/mo) handles multiple teams. Coaches can export a Coach Conflict Card PDF showing pitch counts for tournament directors or league officials.
