CarInsight
Used-car website with an AI consultant that hands a ready lead to the store's WhatsApp.
NestJS / PostgreSQL / pgvector / LangGraph
The problem
The customer browses the store's website, can't find the right car and leaves without a trace. When they reach WhatsApp, the salesperson starts from scratch: budget, use, financing, trade-in.
The solution
CarInsight is the store's website with a built-in AI consultant: semantic inventory search with pgvector, recommendations justified car by car, financing simulation and trade-in valuation in the conversation itself. At the end, the customer moves on to the store's WhatsApp with the conversation summary already written.
The proof
Live at carinsight.com.br, with its own NestJS and PostgreSQL API. The website and API code are public for technical evaluation. Visual design by Diego (Diegowebdesign); integration, chat and AI are built in-house.
