I would guess it’s web requests made during a chat session, e.g. the user asks about kayaks and the AI searches and fetches some pages to put into its context before answering. That’s not really scraping, it’s data being used in the moment in response to a user request, closer to what a “user agent” has always meant in the web world. A crawler would be crawling the site, systematically trying to follow every link and collect what’s there with little to no human involvement.
