Free AI tool for stroke analysis - looking for alpha testers

Hey r/TennisNerds,

I built a free AI-powered tool that analyzes tennis strokes from a 15-second video and provides technical feedback plus personalized equipment recommendations (racket/strings/tension).

It's currently in alpha and I'm looking for testers to validate it before public launch. The tool is completely free, browser-based, and generates a detailed PDF report in 60 seconds.

You upload a clip (serve, forehand, backhand, or volley) and get:

• Technical analysis of your stroke mechanics
• Equipment recommendations based on your technique
• Specific drills to address issues

I think this could be useful for coaches and players who want objective data on technique. No app download required.
