Building a swing analysis tool would love honest feedback from golfers & coaches

[paragongolf]

Hi all,

I’m currently building a golf swing analysis app called Paragon, and I’m trying to sanity-check some assumptions before going any further.

The goal isn’t to replace coaches it’s to provide structured feedback from phone video that mirrors the kinds of things coaches look for (path tendencies, head movement, early extension, tempo, etc.), especially between lessons where maybe things slip from lesson to the next with visual guidance and feedback,

Before I go deeper, I’d really value honest input from people who actually play and/or coach and/or use pros.

A few questions:

1. Do you regularly film your swing? If so, how (tripod at the range, friend holding camera, simulator bay, etc.)?
2. When you review your swing video, what are you actually looking for? Specific positions? Ball flight correlation? Just "does that look right?"
3. Do you use any apps or tools to analyse it? What do you like or dislike about them?
4. If an app highlighted swing patterns that typically align with what a coach might point out (e.g. out-to-in path tendency, excessive head movement, early extension), would you find that useful or would you still only trust a coach’s eye?
5. Would you be willing to follow specific filming guidelines (camera position, height, framing) if it meant more accurate feedback?
6. What would make you not trust AI-based swing feedback?

I’m not selling anything here genuinely just trying to understand real-world behaviour and skepticism before building the wrong thing.

I have videoed my swing at the range, only do it once every several months to check progress I would say. We have a flexible clip & phone holder that we used to use to keep our little one occupied in the car - I use that attached to my golf bag.

I'll watch them back to check my swing hasn't gone back to the dark old ways - so I'm checking my backswing isn't too long, takeaway isn't picked up, not swinging over the top, etc. Don't use any analysis tools other than my own eyes.

If you're talking about AI feedback, I wouldn't mind reading it but I'd also take it with a pinch of salt as it would probably be more generic than what a human coach would offer. I'd probably cherry-pick advice that resonates and leave the bits that don't.

I'd obviously try and get the camera in the right place if it made the app work, yeah.
