AI Chat System for Customer Inquiries
While at SellAnyCar.com, I built the AI chat system that now handles customer inquiries across the chat channels. Until it shipped, every chat inquiry went to a human agent.
The system is mine end to end: the architecture, the agent logic, and the integrations. It routes conversations through multiple models on OpenRouter, so a simple question doesn’t burn a frontier model and a hard one doesn’t get answered by a small one.
The hard part was quality. Early versions went in circles or gave wrong answers, so I built a daily loop of reviewing escalated conversations, fixing the prompts and flows, and redeploying. Over time the escalation rate came down and most inquiries resolved without a human in the loop.
