AI cost diagnostics by a 30-year carpenter

I spent 30 years in Japanese construction — carpenter, site supervisor, CM. I watched homeowners get systematically overcharged. HORIZON SHIELD uses AI to diagnose construction cost estimates. Upload a quote photo and get a diagnosis in 30 minutes. Real case: found ¥500,000 in overbilling on a ¥3,800,000 quote. Backed by Japan's first open construction cost database (87 plans, 88 fraud patterns, CC-BY 4.0) on Zenodo and GitHub. Free AI diagnosis via ChatGPT and LINE.

Hey everyone,
Thank you for checking out HORIZON SHIELD.
I spent 30 years on Japanese construction sites watching homeowners get systematically overcharged. That pain is what drove me to build this.
The core idea is simple: every AI-generated cost estimate now comes with a verifiable 12-character audit hash anchored to Bitcoin. No more “trust me.”
I’d genuinely love your brutal feedback — especially if you work in construction, real estate, or have been burned by renovation quotes before.
What’s the biggest problem you see with current cost estimation tools?
Looking forward to the conversation.
