# Chanteclair

An Italian laundry detergent brand used to illustrate the **variance of [[concept-share-of-model-d10|Share of Model]] across LLMs**. It enjoys a **19% SOM on Perplexity** but is **completely missing from Llama's recommendations** — a concrete demonstration of the binary nature of LLM inclusion described by [[concept-mention-rate|mention rate]] and [[claim-no-page-two-in-llms]].

**Enrichment:** Canonical URL **chanteclair.it**. Italian household cleaning and laundry-detergent brand; used in SOM discussions as an example of model-specific visibility — strong presence in some models, absent in others.
