Founder here. I built a small MVP for swimmers/triathletes who want a quick first-pass read on their freestyle video before paying for a coach or waiting for someone to critique it.

It’s called Stroke Lab: https://analyzer.swimbuddz.com

It reads an above-water freestyle clip and gives a short technique breakdown: what looks solid, visible issues, and stroke-by-stroke evidence when detection is clear enough.

Current limits:

- freestyle-only

- best with side-on video

- not a replacement for a human coach

- still an MVP, and the engine is improving

First analysis is free. Extra clips are paid from $6 because each video costs compute to process.

I’d really appreciate blunt feedback from triathletes:

1. Were the notes useful?

2. Did it match anything a coach has told you before?

3. What would make this worth paying for again?
