It definitely means something, probably an app designed around being interacted by with an LLM, upon first hearing it. Browser interaction is one of those things that is a great killer app for LLMs IMO.

For instance, I just discovered there are a ton of high quality scans of film and slides available at the Library of Congress website, but I don't really enjoy their interface. I could build a scraping tool and get too much info, or suffer and use just clicking through their search UI. Or I could ask my browser tool wielding LLM agent to automate the boring stuff and provide a map of the subjects I would be interested in, and give me a different way to discover things. I've just discovered the entire browser automation thing, and I'm having fun have my LLM go "research" for a few minutes while I go do something else.

Well yeah it's kind of ambiguous, it's just our way of saying that we're trying to use AI to make testing easier!
