I've got a shelf full of physical cookbooks -- The New Best Recipe, The Food Lab, an Ottolenghi book, On Food and Cooking, etc. I like them, I've read through all of them, I sometimes use them for inspiration.

It's rare that I actually cook directly from them -- usually, that'd be big and fancy stuff or stuff I'm very unfamiliar with; in both cases I usually take the time to cross reference whatever the cookbook says with additional resources from the internet.

ChatGPT, on the other hand, I frequently use when or before cooking (and I cook virtually every day).

It's great when I only have a vague idea based on stuff in the fridge; five minutes later I've got a checklist I can reference. If it hallucinates something that I flat out don't think will work or, much more likely, comes up with something that I don't want or cannot do for lack of ingredients or time or whatever, I'll tell it to adjust the recipe and it does.

It's also great when I feed it a couple of existing recipes (from real people) to compare and contrast and integrate and reformat in a way that's most useful to me, e.g. a tabular format, or scaled to a different serving size.

With all that said, the AI based recipe sites don't really do it for me, either. If I want to cook purely AI generated recipes, a chat interface works fine -- and probably better. What I really want is an AI tool that helps me curate my own recipe collection. E.g. I want to ask it "I'd like to make Ramen, how did I do it the last time, what were my notes" and when it's done I want to tell it "ok, this was fine, I decided to double the mirin and next time I'd marinate the eggs longer" and have it update the recipe.
