Who hurts
Solo tradespeople: plumbers, electricians, landscapers, who quote from their van.
The problem
Quotes get written at 9pm after a full day of work, or not at all. Slow quotes lose jobs to whoever replied first, and the trade knows it.
What you build
Photograph the job, speak a few notes, and get a formatted quote with line items priced from the trade's own rate card and local material costs, reviewed and sent from the phone in two minutes.
Why now
Vision models can identify fixtures and scope from a photo, and this audience already runs the whole business from a phone.
Validate it this week
Ride along with three trades for a day each. Write their quotes on your laptop from their photos. You'll learn the pricing rules that make or break it.
Why you'd keep winning
Per-trade rate card structure and local material pricing. Deeply unglamorous, which is exactly why it holds.
The honest risk
Hard audience to reach. They don't read tech newsletters. Distribution runs through suppliers, trade associations and word of mouth.
The prompt is written to make an AI argue with you before it writes code. That first round of pushback is worth more than the scaffold.
