AI based applications

Hello,
Programs that work based on AI, do they use existing AI libraries in programming languages ​​or do they have their own AI? For example, a program that is supposed to advise someone about diet based on AI, can it use AI libraries available in programming languages ​​or does it need its own AI?

Thank you.

Who says all diet apps use AI? I reckon a lot of them use simple decision trees based on some input such as gender, age, current weight and goal.

If it must use AI then I suppose both existing as well as new libraries could be used. If a library exists and gives good results, use it, otherwise create a new one.

Hello,
Thank you so much for your reply.
1- I didn’t say all diet programs use AI, but some do. If one wants to do this in a language like Python or Julia, which libraries are suitable?

2- What do you mean by “otherwise create a new one”? Do you mean building something like TensorFlow or PyTorch?
