This could arguably be because Google is a lot better than ChatGPT right now.

I asked chatGPT to create a meal plan, which it did, and all the recipes looked great, except, clicking the links for the recipes showed that they were completely made up, and either the links didn’t exist or were generated links, which in case they did were recipes for something completely different.

Doing the same search at Google may have required a couple of clicks, but all the top listing would return a weekly meal plan.
