THE PROBLEM

The Friction And The Idea

The Friction And The Idea

As a martial artist who uses video feedback as a tool to improve technique, I always re-watch my training sessions and try to analyze the movements. The problem was that the videos were getting lost among other things, and reviewing them on the phone or even screenshot on the TV was lacking ways of being able to do a proper analysis. For example, slow motion, time-stamped comments, and rovers for future reference.

FOR WHO

Martial Arts Coaches

Martial Arts Coaches

This is a very niche product by martial arts coaches. They would love to have an environment where they can keep and build their legacy. This is based on primary research, and the research is being continued with an actual working product.

PERFORMANCE STACK

  • Supabase (Auth/DB)

  • Bunny Stream (CDN)

  • Daily

THE APPROACH

I am the user, solving a problem from personal lived experience — solo full-stack execution as a Vibe Engineer: design → development → deployment, rapidly iterated with real students using AI-assisted tools.

UPLOAD & REVIEW

Upload your training and tag a coach.

Upload your training and tag a coach.

Upload videos from your training sessions to train more effectively and track your progress over time. If your coach is on the platform, simply tag them. They'll receive an email and can provide detailed feedback using the built-in Video Analysis Studio.

TIMESTAMPED FEEDBACK

Video analysis studio (VAS)

Video analysis studio (VAS)

The VAS lets you or your coach review training videos with professional analysis tools. Add drawings, arrows, shapes, and annotations directly onto the video, with every comment and markup timestamped so feedback is linked to the exact moment it applies.
