I Built an AI Brain for Youth Coaches. Here's Why It Should Exist at Scale.

I coach youth sports. Last season I was spending as much time on administrative overhead as actual coaching, and I've been building AI systems professionally for years.

That bothered me enough to build something about it.

What I built

The Coach's Assistant is an AI Brain built on Notion and Claude. Not a form. Not a spreadsheet. A structured knowledge system that thinks with you instead of just storing data. I built it around two problems: game planning and player tracking.

On the game planning side: I describe our upcoming opponent, our roster's current strengths and gaps, and what we've been working on in practice. The system helps me build a formation, think through matchups, and structure a game-day brief I can deliver to a group of third-graders in 90 seconds before the opening whistle. That constraint matters. A sophisticated plan that can't be communicated fast is no plan at all.

On the player tracking side: every kid gets a development log. Notes from practice, what they're working on, where they're improving. I can pull up any player's history before a parent conversation and actually remember what happened three weeks ago. That sounds basic. For a volunteer managing 12 kids on top of a full-time job, it's the feature I use most.

How it works

Notion provides the structure. Claude provides the thinking layer. I use it conversationally: describe the situation, get back organized output. No forms to fill. The whole thing behaves less like software and more like a well-organized assistant who was at every practice.

The problem is bigger than one coach

The same overhead falls on every volunteer coach running a recreational youth sports team. Game planning, player development, parent communication, scheduling. That's an enormous, underserved market. Most coaching software is built for elite academies or professional programs. The recreational coach gets a group chat and a shared Google doc.

The architecture extends further than one coach's needs. Parents could have visibility into their child's development: not just game scores, but actual notes on what their kid is working on week to week. Leagues and clubs could license it as a white-label platform. Coaching directors could get rollup views across an entire program. None of that requires rebuilding from scratch. The structure already supports it.

What I'd do differently

I built the player tracking side too granularly at first. Individual drill ratings, weekly attendance flags, skill scoring by category. Most of it I never used. What I actually needed was a simple running note per player and a way to scan the whole roster before a game. The simpler version would have taken a quarter of the time to build and done 90% of the job.

The pitch

I built this for myself. The problem is validated. I'm looking for partners or acquirers who want to take it somewhere bigger.

If you're in youth sports, coaching education, or sports technology and this sounds interesting, I'd genuinely like to talk.
