For example, I'm looking at sleeping pads for camping. If I type "sleeping pad" in ChatGPT, it tells me what a sleeping pad is. If I type it into Google, it lists products, places to buy them, and some reviews. If I type "best sleeping pads", ChatGPT gives me a list but without details or sources. If I type into Google, I get a list of reviews which I have to read but has context.
