Lexus AI Concierge

To make Lexus more approachable, we built an intelligent, intuitive digital concierge. This isn’t a chatbot. It’s an AI-powered guide that helps users navigate the website with ease. Whether a prospective buyer or a returning customer, visitors can ask questions, and the AI Concierge will deliver tailored, easy-to-digest responses using Lexus data from multiple sources. Beyond simply answering questions, the AI Concierge presents comparisons, lists and tables, automatically selecting the most useful format. It also integrates a built-in color selector, allowing users to visualize different car colors in real-time. Most importantly, it helps guide users to their next step, whether that’s exploring model details, booking a test drive or finding a dealership. Under the hood, the AI Concierge leverages retrieval-augmented generation (RAG) to pull in relevant Lexus knowledge, refining user queries before passing them to a large language model (LLM). This ensures responses are accurate, structured and engaging. Strict guardrails prevent personal data processing, while a tone-of-voice guide keeps interactions polished and on-brand. https://www.valtech.com/work/lexus-europe/
