AI tool that generates professional contractor quotes and estimates in 60 seconds.
u/Upbeat_Exam5410 · Reddit
Built an AI quoting tool for contractors — my neighbor was losing jobs because quotes took too long My neighbor runs a small moving company. Good guy, works hard. He kept losing jobs because by the time he emailed a quote, the customer had already booked someone else. He'd spend 20-30 minutes writing each estimate — pricing research, word it professionally, format it, send it. By the time it went out, it was too late. So I built QuickQuote AI.

It’s a web app —

Automatically route each prompt to the cheapest capable model to cut API costs.
u/ASDKING100 · Reddit
Launched an AI API router tonight, and found a bug hours in that would've taken real payments without ever upgrading the account Built LLMLite over the past few weeks — it classifies each prompt and routes it to the cheapest model that can actually handle it, instead of hitting GPT-4o for everything. Free tier, no card needed to try it. Tonight, right as I was about to launch, ran a real transaction to test the payment flow end to end. Paddle processed it, webhook fired, signature verified
