What is Brave Leo AI?

Brave Leo AI is an on-demand AI fetcher operated by Brave. 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 Brave's assistant.
