trivago builds Smart AI Search using Vertex AI and LLMs for natural-language hotel discovery
trivago had pursued free-text hotel search since 2014 but the technology was not ready; when generative AI arrived the team faced limited expertise in the new technology, needed the right partnership to build it, and had to integrate a conversational interface into a highly optimised existing search product without disrupting it.
How it works
Common implementation structure
How this type of workflow is generally built, generalized across documented cases — not tied to any one vendor's stack. Click any stage to read what happens there. Specific products that implement these stages appear in “Tools commonly seen” below.
Stage 1 · User submits natural-language query
Users type complex hotel preferences in free text rather than toggling multiple filters.
Tools used
Large Language Models (LLMs)Vertex AI Search
Outcome
trivago launched Smart AI Search (currently in beta) enabling users to find hotels using complex natural-language queries, aiming to make travel planning smarter, faster, and more intuitive.
What failed first
Early AI search prototypes revealed limitations, and the team had to trust in rapid AI capability evolution before a full product build was viable.
