I built an AI caption tool for gym creators — here's why and what I've learned so far

Hey Indie Hackers — I'm Tyler, a gym lover from the UK who got fed up with one specific problem.

Every fitness creator I know spends way too long writing captions. You've done the workout, filmed the content, and then you're stuck staring at a blank box trying to think of something to say.

So I built IronCaption — ironcaption.com — an AI caption generator made specifically for gym creators and PTs. Not a generic tool with a fitness skin on it, something actually built for our world.

Currently at 0 users and trying to get to 20 paying customers as my first milestone.

Happy to answer any questions about the build or the niche. Would love honest feedback from anyone who tries it."
