Skeptic to believer in 20 minutes flat

My cousin runs a small landscaping crew in Tucson. Last month he showed me how he uses an AI scheduling tool to plan routes for his guys. I laughed at first. Thought it was overkill for three trucks and a mower trailer. But he walked me through a Tuesday morning where the AI shuffled jobs after a client called in sick. It rerouted everyone in under a minute. I do bids and estimates all day, so I asked it to run a mock quote on a patio job I had sitting on my desk. It caught a materials cost I missed by about $400. That hit different because I've been doing this work for 14 years. Now I'm curious if any of you use AI for on-site estimating or just office side stuff. What's the tool that actually saved you real money on a job?
