Tennis Stroke Analyzer

What is Tennis Stroke Analyzer?

Tennis Stroke Analyzer is an AI tool that grades your tennis strokes from a video the way a coach would, breaking each shot into its components and pointing out exactly what to fix. You upload a clip of your forehand, backhand, or serve and the AI identifies the stroke, then reads your grip, preparation, swing path, contact point, follow-through, footwork, and kinetic chain before scoring it out of 100. Most players sense that a stroke is letting them down but can't see why, because the swing happens in a blur and you can't watch yourself while you play. Filming helps, but you still need a trained eye to tell whether your forehand sprays because of late prep, a wristy swing, a cramped contact point, or no shoulder turn, or whether your serve breaks down at the toss. This tool gives you that eye on demand. It detects the common faults (late preparation, wristy strokes, poor contact point, no unit turn, a low or inconsistent toss) and then does the most useful thing a coach does: it tells you the one fix that matters most instead of overwhelming you. Stroke faults tend to cascade from a single source, so fixing the right one first is how players actually improve.

How Tennis Stroke Analyzer Works

Upload a video of your stroke, ideally a clean side or rear angle with your whole body and the racket in frame. The AI identifies whether it's a forehand, backhand, or serve, then tracks your body and racket through the swing and compares them against that stroke's sound technique. It checks your grip, your unit turn and preparation, and your swing path (low to high and on plane), then reads your contact point, which decides most of your control and power. It examines your follow-through, footwork, and whether you're using the kinetic chain or arming the ball. For serves it grades the toss, the trophy position, and pronation through contact. From this it names the specific faults it sees and rates how severe each one is. Finally it isolates the single highest-leverage fix, explains why it's the root cause (late prep forcing a cramped contact point, for example), and prescribes a couple of targeted drills. Adding notes about the stroke and your level makes the read sharper.

Benefits of Tennis Stroke Analyzer

• Get a coach-style read on your tennis strokes in seconds without booking a lesson or a video session with a pro.
• See a component-by-component breakdown of grip, prep, swing path, contact point, and footwork so you understand where the stroke breaks down.
• Find out whether late prep or a wristy swing is causing your errors and how severe it is instead of guessing from where the ball lands.
• Get the single priority fix rather than a confusing list, because stroke faults usually cascade from one root cause like a late unit turn.
• Receive specific drills tied to your fault with the feel you're chasing, so practice time turns into real change.
• Track progress by uploading a new clip after working on the fix and comparing the new score and breakdown.
• Learn what a sound stroke looks like at each phase so you stop grooving the habits that cap your level.

Tips for Best Results

• Film from a consistent angle (side-on or from behind) with your whole body and racket visible through the swing.
• Tell the tool which stroke you're hitting and your level so it grades against the right standards.
• Add notes about what you think is wrong so the analysis targets your actual problem.
• Capture a full, normal swing rather than a slow rehearsal, because rehearsal moves hide the faults that show under real tempo.
• Work on only the one priority fix between sessions, since chasing every cue at once stalls progress.
• Re-upload a fresh clip after a week of drills to see whether the priority fault improved and the score moved.
• For serves, film from behind so the AI can see your toss height and placement clearly.

Popular Use Cases

• Club players diagnosing why their forehand or serve keeps breaking down in matches.
• Beginners learning what good preparation, swing path, and contact point look like as they build their strokes.
• Intermediate players trying to break a plateau by fixing the one root fault holding their game back.
• Players between lessons checking whether they're grooving the change their coach asked for.
• Anyone whose serve is inconsistent who wants to see whether the toss is the culprit.
• Parents and junior players reviewing strokes together with a structured, jargon-light breakdown.
• Players preparing for a match who want a quick honest read on whether a stroke is holding up.
