After 10 years on the mats and reaching brown belt, I realized I’m still making "white belt" mistakes. So I started coding a solution
Hi everyone,
I’m a brown belt and I’ve been practicing judo for about 10 years, and I’m finally preparing for my black belt exam.
But here’s the problem: the closer I get to that goal, the more I realize my fundamentals aren’t as perfect as I thought.
I film my uchi-komi, I rewatch my randoris, and I can feel that something is off with my balance or my hip placement. But without my sensei pointing it out, I often can’t quite identify what exactly is wrong.
Since I’m also a developer, I decided to stop guessing and start building something.
So I started working
The idea is simple:
You upload a video of your training or fight, and the AI analyzes it — tracking things like center of gravity, attack angles, and timing — to show exactly where power or balance is being lost.
Technically, it’s been a bit of a nightmare
The thick judogi makes it difficult for the AI to detect joints and body positions accurately. But I’m determined to figure it out.
i built this JudoAi page to see if this could help before doing anything else
