I launched a free AI tool portfolio for tradespeople 15 days ago — here's what actually happened

I'm a 5th-generation electrician in Central Texas. I build estimates in my truck, write review responses at 10 pm, and post job listings on my phone between jobs. I got tired of it, so I built tools to do it for me — then put them on the internet for free.
That was 15 days ago. Here's the honest update.
What I built
Tradeskit.ai is a portfolio of free AI tools for tradespeople and local service businesses — roofers, painters, HVAC, landscapers, cleaners, pest control, fencing, dog groomers. Six tools live:

Estimate generator (the workhorse — 75% of all usage)
Invoice generator
Review response generator
Job description writer
Follow-up text generator
Agent-readiness scan (new — more on this below)

The free tier is 5 uses/day, no account. Pro is $19/month for unlimited use and a saved rate card that builds send-ready exact-price quotes instead of ballpark estimates.
The numbers after 15 days

472 total visits, 213 unique visitors
32 tool runs (15% run rate — the number I'm working to improve)
1 paying Pro subscriber
3 email subscribers
27 Google impressions, 4 clicks — all branded so far, no keyword rankings yet
45+ trade-specific landing pages indexed

What's working
Facebook groups. One post in a painting contractor's group hit 33 comments and generated 3 warm leads in a single afternoon. That's been the only real distribution so far — organic, no ads, no budget.
The posting is inconsistent because I'm running an active electrical business at the same time. That's the honest constraint.
What I'm building next
The agent-readiness scan is the thing I'm most excited about. It scores any local business website 0–100 on whether AI assistants (ChatGPT, Siri, Perplexity, Google AI) can find, trust, and book them. I ran it on local HVAC shops near me:

One shop: 0/100
Another: 15/100
Another: 23/100

The offer is $750 to fix it + $99/month monitoring. I'm going to sell it myself to land the first 10 customers. That's the branch from the original "fully hands-off" plan — but we built something worth selling, so I'm selling it.
What I haven't figured out yet
Consistent distribution without burning out. SEO is a waiting game (3–6 months minimum for a new domain). Facebook group posting is manual and falls apart on long workdays. The real answer is probably getting the first few agent-ready clients and letting word-of-mouth do more of the work while the SEO compounds.
Happy to answer questions — especially from anyone who's done the free-tool-to-paid-service motion before. How did you bridge the gap between "people love the free thing" and "people pay for the service"?
