Bang me sideways, "AI-native" is a thing now? What does that even mean?
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!
