Building a Million Dollar AI App - Day 1: AI Coaching with OpenAI Vision

Day 1 of building a million dollar AI app. I'm 20 years into software development and I use AI agents and tools like Lovable to ship faster than I ever could by hand. In this video I walk through the AI coaching feature I just implemented in Stable Manager Pro, an app that helps riding instructors give better feedback to students.The feature uses OpenAI Vision to analyze a photo of a rider on a horse and return real coaching feedback: overall balance score, posture analysis, hip engagement, upper body angle, and specific coaching cues. The output reads like what a real instructor would say after watching a student ride. Two years ago you couldn't build this. Today it's one API call.What's covered:How OpenAI Vision analyzes a rider's posture from a single photoThe coaching output: balance, posture, stirrup position, hip engagement, upper body angleWhy this works for equestrian coaching specificallyHow I'm using OpenAI and Claude together to ideate featuresWhat's coming in v1.1: video upload, FFmpeg frame extraction, multi-frame analysisThe app is stablemanagerpro.com. We're in soft launch and onboarding stable owners, students, and instructors now. Web app first, with iOS and Android coming.This is Day 1 of an ongoing series where I show how I build apps using AI tools instead of hand-coding everything. Subscribe to follow the build.
