AI stroke and swing analysis, from a video on your phone

Film a few strokes or a rally. Court Rally's AI reads the video frame by frame — technique, footwork, body position, contact point — and tells you what's working, the one fix that matters most, and the drills to make it stick. About a minute, for any court and racket sport.

How the video analysis works

1

Film from the side

Whole body in frame, a few strokes or a rally, up to five minutes. Film in the app or pick a video from Photos.

2

The AI reads it frame by frame

It finds each stroke in the clip, names it, and reads the moments that matter — like a slow-motion video review with a pro.

3

Get the fix and the drills

What's strong, what's close, the one change worth making first, and drills to build it — saved to your account on every device.

One app, four sports

Sport-specific AI analysis for every court

Each sport is read in its own terms, with its own strokes and its own fixes.

Beyond one clip

Analysis that turns into practice

  • ✓
    A training week built around the fix

    The AI coach writes the week — drills, minutes and key points — so the change the video pointed at gets practiced, not just noticed.

  • ✓
    Your coach, looking at the same read

    Send a clip to your coach for review. They see the video and the AI's analysis together, and mark each point right or wrong.

  • ✓
    Progress you can watch

    Every clip and every read stays in your account, so this month's swing sits next to last month's.

  • ✓
    Built for juniors and their families

    Players under 18 are profiles run by a parent or coach. Nobody outside the family sees a clip until you share it.

Questions about AI video analysis

Can AI analyze my tennis or pickleball swing from a phone video?

Yes. Film from the side with the whole body in frame — a few strokes, a rally drill, or a serve basket. Court Rally finds each stroke in the clip, reads it frame by frame, and comes back with what's working, what's close, the one fix that matters most, and drills for it, usually in about a minute.

What does the stroke analysis look at?

Technique and body position: preparation, racket or paddle path, contact point, balance, weight transfer, footwork and recovery. Every point in the read names the frames it comes from, so you can see exactly what it saw.

How long can the video be?

Anything from a few strokes up to five minutes. A longer rally video is read at more moments, and you can point the read at the part of the clip and the player you mean.

Which sports does it cover?

Tennis, pickleball, badminton and table tennis — the court and racket sports. Each sport is read in its own terms: a pickleball dink is not judged like a tennis forehand.

What does it cost?

A read costs $1.99 on its own, or from $0.91 with a credit pack or subscription — packs never expire. New accounts get 90 free credits — enough for a clip and about two weeks of training plans — with no card needed.

Does it replace a coach?

No — it fills the days between lessons. Your real coach can open the same clip and the AI's read from their own phone, agree or correct it, and adjust the training plan. Coaches use Court Rally for free.
