I was 11. My mom's back hurt. I drew an exoskeleton.
It never got built. Not because the idea was wrong because I had no machine to build it with.
Fifteen years later, I built the machine.
The Problem
Software has Cursor. Hardware has nothing.
91% of hardware startups fail. $500K minimum before a single dollar of revenue. A $50 trillion physical economy with zero AI tooling.
That changes now.
What JAI Does
You type English. A physical device comes out.
"Design a membrane-free microfluidic device to filter microplastics from tap water."
< 3 minutes later: STEP file. G-code. BOM. Physics validation report.
I 3D-printed it. Shipped it to a lab in India. They tested it independently.
> 95% microplastics removal. Presented at UNM National Conference 2026, alongside Stanford PhD researchers.
Not a render. Not a mockup. A physical object — made from one sentence.
How It Works
Zero hallucinated physics.
$$\text{English} \xrightarrow{\text{NLP}} \text{Constraints} \xrightarrow{\text{FEA·CFD}} \text{Validated Geometry} \xrightarrow{} \text{STEP + BOM}$$
Air-gapped. Local Ollama. $0 cloud cost. ITAR-compliant. 100% STEP compilation across 28 benchmarks.
The Business
Free → Export #6 → $99/month. That's it.
$$\text{CAC} = \$35 \quad \text{LTV} = \$1{,}188 \quad \text{LTV:CAC} \approx 34\times \quad \text{Payback} < 30 \text{ days}$$
Why Now
WordPress democratized publishing. Shopify democratized commerce. Cursor democratized software.
JAI democratizes everything physical. $50T. Untouched. Until now.
The coding world got Cursor. The physical world has been waiting. That 11-year-old finally has his machine.
