Show HN: AI for Building Design, Planning, and Permitting

Saw Spacial recently — it's an AI tool that helps figure out what can be built on a piece of land, based on local zoning rules.

You enter a parcel and it generates 3D massing, site plans, and other planning details in a few minutes. Seems like it could be super helpful for early-stage architecture or development work.

It looks like you used AI-generated videos for customer testimonials. This should be illegal

And the testimonial photos, they're all AI generated

I came here to make this exact comment. What a horrible idea! The whole point of customer testimonials is to display trust - this does the opposite.

pscsbs, are you affiliated with this company? when you say "saw" it makes it sound like you're just someone submitting this because you found it interesting and have no connection to the company. not sure I've ever seen someone submit a "Show HN" who was not affiliated with the project they're submitting.

I'm asking mostly because I'd be very interested in something like this, but the price point seems significant if the turnaround is truly "a few minutes." I mean, yes, those deliverables you list would cost that much (and more) if a person was producing them, but if what you're delivering gets done in a couple of minutes I'd be hard-pressed to believe that your gross margin wouldn't be extreme unless the R&D/capital cost was so huge to create that custom "AI" that you needed to charge this to ever get a return on that capital. maybe you could quantity "a few minutes" and then talk a bit more about how much back and forth there is after that initial few minutes and how much/many human resources are involved in those back and forths.

Everyone in the space that has a longer than 10-minute turn around time and pricing greater than single digit dollars is using humans for a substantial part of it and is not AI, I promise you.

Yeah I doubt there's any AI here, they might even use other tools like say YC's up.codes for the compliance with local codes, then they arbitrage cheap labor at a premium price because "AI"
