Swimming Stroke Analyzer

What is Swimming Stroke Analyzer?

Swimming Stroke Analyzer is an AI tool that grades your swimming technique from a video the way a coach would, breaking your stroke into its key components and pointing out exactly what to fix. You upload a clip of yourself swimming (filmed from the side, from above the pool, or underwater) and the AI identifies your stroke, then reads your body position, catch and pull, hand entry, breathing, kick, and rotation before scoring the whole thing out of 100. Most swimmers know they're working harder than they should be but can't see why, because everything happens underwater and out of sight while they're focused on not drowning. Filming helps, but you still need a trained eye to tell whether your slow times come from a dropped elbow in the catch, a crossover entry, a head that lifts to breathe, or hips that sink. This tool gives you that eye on demand. It detects the common faults (dropped elbow, crossover, head lifting, scissor kick, over-gliding) and then does the most useful thing a coach does: it tells you the one fix that matters most instead of overwhelming you with the whole list. Stroke faults tend to cascade from a single source, so fixing the right one first is how swimmers actually get faster.

How Swimming Stroke Analyzer Works

Upload a video of yourself swimming, ideally a clear side view, an overhead view, or an underwater clip with your whole body in frame. The AI first identifies your stroke, then tracks your body and limbs through the stroke cycle and compares them against that stroke's sound technique. It checks how flat and high your body rides, your head position, and the catch and pull, where the early vertical forearm decides how much water you actually hold. It reads your hand entry for crossover, your breathing timing, your kick (size, tempo, and whether it comes from the hips or the knees), and your rotation along the long axis. From these positions 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 (sinking hips often force a head lift, for example), and prescribes a couple of targeted drills with the feel you're going for. Adding notes about your stroke, the camera view, and your level makes the read sharper and more personal.

Benefits of Swimming Stroke Analyzer

• Get a coach-style read on your swimming in seconds without booking a video session or a one-on-one with a club coach.
• See a component-by-component breakdown of body position, catch, entry, breathing, kick, and rotation so you understand where the stroke leaks speed.
• Find out whether a dropped elbow or a crossover entry is robbing your pull and how severe it is instead of guessing from your splits.
• Get the single priority fix rather than a confusing list, because stroke faults usually cascade from one root cause like a sinking body position.
• Receive specific drills tied to your fault with the feel you're chasing, so pool time turns into real technique change.
• Track progress by uploading a new clip after working on the fix and comparing the new score and breakdown.
• Learn what efficient technique looks like in your stroke so you stop reinforcing the habits that make swimming feel like a fight.

Tips for Best Results

• Film from a consistent angle (side-on, overhead, or underwater) with your whole body visible through the stroke.
• Tell the tool which stroke you're swimming and your level so it grades against the right standards.
• Add notes about the camera view and what you think is wrong so the analysis targets your actual problem.
• Capture a steady, normal-effort length rather than an all-out sprint, because faults show up clearly at relaxed pace.
• Work on only the one priority fix between sessions, since chasing every cue at once is how technique falls apart.
• Re-upload a fresh clip after a week or two of drills to see whether the priority fault improved and the score moved.
• An underwater clip reveals the catch and kick far better than a poolside view, so try one if you can get it.

Popular Use Cases

• Triathletes and open-water swimmers trying to swim more efficiently and save energy for the bike and run.
• Adult learners checking whether their body position and breathing are holding them back as they build distance.
• Masters swimmers diagnosing why their times have plateaued despite putting in the yardage.
• Club swimmers between coached sessions verifying they're grooving the technique change their coach asked for.
• Parents and young swimmers reviewing a stroke together with a structured, jargon-light breakdown.
• Lap swimmers who want instant feedback after filming a length instead of guessing what felt inefficient.
• Swimmers preparing for a race who want a quick honest read on whether their stroke holds up at pace.
