You wont be able to make tool/saas by coding using AI without any idea how to code. This wont happen,
you are dreaming mate.
Learn python or js, some basics, than move on to your project using AI. There is no way around this so stop looking as you wont find (except for no-code tools).
You will find many videos how people made X or Y using AI with little coding skills - but these people know how to code, just do it faster with chatgpt.
Personally its faster for me to tell chatgpt "i want X" and correct chatgpt mistakes than write everything myself. But I still need ability to fix chatgpt bugs.
Also solutions suggested by chatgpt are not always best, sometimes are just stupid. You need coding skills to know when AI tool is helping you, and when is bullshit.
If you want python path:

If you want JS path:

P.S. Consider fact that knowing how to code make you able to handle bigger stuff than just simple projects. Simple projects bring beer money, serious bring car or house money. Dream big, not small
