Is the baseball swing analyzer really free?

Yes. Upload a swing or try the sample. There is no account, no download, and no paywall.

Is this an AI swing analyzer?

Yes. It uses AI body-pose detection to find the hitter's skeleton in every frame, then grades head, posture, and balance. The AI runs right in your browser, so the video never leaves your device.

Do I need to download an app?

No. The analyzer runs in your web browser. The SwingDino app adds exit velocity, a home run derby, and progress tracking over time, but the swing read is free on the web.

Can it analyze a softball swing?

Yes. It reads fastpitch softball and baseball swings the same honest way, from a single side-on view.

What video works best?

Film side-on (from the side, not behind), with the full body in frame and decent light. A normal phone video of one swing is perfect.

How accurate is the swing analysis?

It is an honest, directional read of head, posture, and balance from one camera, not a radar gun. When it cannot get a clean look, it says so instead of faking a grade.

Does it measure bat speed or exit velocity?

Not from a video. Bat speed and exit velocity need sensors or depth, so the analyzer leaves them out rather than guess. The SwingDino app measures exit velocity from a high frame rate camera.

Completely. The video and the pose stay in your browser. Nothing is uploaded and we keep only the numbers, which makes it safe for kids' swings.

Upload a swing and an AI reads it in seconds, for free.

What the swing analysis reads

This free baseball swing analysis reads three things well from a single side-on view. Bat speed and exit velocity need sensors or depth, so the free web tool leaves them out instead of guessing.

Quiet head

Whether the head stays still and on the ball or drifts off it. The single most common thing a young hitter can fix, and a camera can see it clearly.

Posture

Whether the hitter stays down in their legs through contact, or stands up out of the swing. The shape of an athletic turn.

Balance and base

Whether weight stays centered and stacked over the feet, or leaks out toward the pitcher. Read from the side, where the whole body is in view.

Built for young hitters

The analyzer is made for youth baseball and fastpitch softball, ages 4 to 16, where staying down and keeping a quiet head matter far more than a radar number. You get one thing to work on and a drill to do it, in words a kid understands. See the full swing analysis feature.

Private by design

Nothing is uploaded. The video and the pose stay in your browser, and we keep only the numbers. No account, no sign-in, no file leaving your phone, which is exactly how a kids' swing tool should work.
