Selling AI to people who use hammers: My battle with the "Old School" trades

I spent the last few months building what I thought was the "future of electrical work." It’s an AI-powered tool called Zing² that helps contractors pass inspections by giving them instant NEC code citations and verified calculators.
Coming from a tech background, I thought the value proposition was obvious: Why spend 20 minutes flipping through a massive, greasy code book when you can get the answer in 3 seconds?

Then I started talking to actual electricians.

I quickly realized that my biggest competitor isn't another app or a better LLM. My competition is a 30-year-old notebook tucked into a visor and a "we’ve always done it this way" attitude.

The "Toilet Test"
I got a message at 5:45 AM today from a contractor. He told me he was browsing the app while sitting on the toilet before heading to the job site.
At first, I laughed. But then it hit me: That’s the "Product-Market Fit" for the trades. These guys don't have time for a "demo call" or a 10-page onboarding guide. If your tool can't provide value in the five minutes they have between waking up and getting in the truck, you've already lost them.

The SEO Wall
On top of the "old school" mindset, I'm fighting a massive SEO battle. I am an indie dev trying to rank for keywords owned by billion-dollar wire companies, the NFPA (the people who literally write the code), and government agencies.
I can’t outspend them. I can’t out-backlink them.
My only edge is speed and empathy. Their sites are slow, bloated, and full of PDFs. My tool is built for a guy standing on a ladder with one hand on a phone and the other on a junction box.

The Question
For those of you building in "low-tech" industries: How do you break through the skepticism? Do you lean into the tech, or do you hide the "AI" behind a simple interface and just call it a "tool"?
I’d love to hear how others are handling the transition from building the tech to actually convincing a "boots-on-the-ground" user to trust it.
