What is Sarashina Search?

Sarashina Search is an on-demand AI fetcher operated by SB Intuitions. It retrieves a page only when a user explicitly asks an AI assistant or agent to read, summarize, or act on a specific URL. Because it is triggered by real user intent rather than bulk crawling, blocking it mainly prevents users from pulling your content into SB Intuitions's assistant.
