This is interesting and cool for entertainment, but it's extremely hard to picture using this as a replacement for an architect.

We're building an ADU right now and the floorplan design was a very small part of what our architect did. So much more of the value came from the relationships he has with the structural and geotechnical engineers we used as well as the relationship with our city building department.

This really strikes me as a product in search of a problem.

Maybe a homeowner could use this for initial planning before finding an architect to use, but at that point you're competing with pencil and paper.
