The tool looks sick. I think the copilot vs black box approach is great. I found the demo to be enjoyable and satisfying to watch despite having no experience in the concrete estimation industry.

This is out of my wheelhouse but had a couple of thoughts. When you clicked P1, it found all of them. What happens if it doesn't? This would have been good to see in the video.

Also, I'm sure people familiar with these documents will have no trouble but was thinking it could be cool to do some effect to make references glow/be more noticeable at least temporarily when you are skipping around to them. Maybe some zoom controls too.

Anyways, good luck!
