ATHLETIC HITTING DEVELOPMENT / SELF-SERVICE EXPERIMENT
UPLOAD A SWING.
SEE YOUR MOVEMENT.
One ordinary phone video. No sensor. No account required for this research preview. See observable body-position changes and the matching AHD teaching lessons.
ON-DEVICE BODY-POSE PREVIEW NO NUMERICAL SWING GRADE YET
What this preview does: estimates 2D body landmarks and reports descriptive head, foot, trunk, and wrist movement. What it does not do: detect the actual bat or ball, measure precise 3D hip separation or contact angle, diagnose faults, or calculate a valid BK Swing Grade. It is an original AHD research preview, not a licensed professional comparison.
STEP 1 / ONE SWING
Choose a swing from your phone
0%
Choose a swing video to begin.
STEP 2 / ONE LARGE VIDEO · NO SPLIT SCREEN
Your swing, full view.
Length:
Play, pause, scrub, or rotate your phone to inspect the SAME swing at full size. The overlay is body landmarks—not actual bat tracking.
ONE SWING. ONE SCREEN.
Select a video above to see it here. No reference video to synchronize. The observations appear below when the scan finishes.
Your swing video stays on your device: this page does not upload it. Third-party MediaPipe software and model files are downloaded and may collect technical telemetry. Obtain the athlete's or guardian's permission before using this preview.
03 / OBSERVATIONS
What the phone video actually shows
Upload and analyze a video to see evidence. If the body is not visible enough, we will say so instead of giving a made-up grade.

2D movement observations
No numerical grade is available.
WHAT COMES NEXT
Building toward the real BK Digital Twin.
Teach the tracker to identify the actual knob, endcap, barrel route and ball contact across ordinary phone frames.
Use a coach-tested AHD rubric and real swing benchmarks so performance scores are meaningful rather than arbitrary.
Rank the athlete's validated priorities and provide a training path from the AHD Four Pillars.
