These ai shopify store builders that are trending that "create landing page plus logo plus products etc, we all knows that building these saas(or shopify apps) isn’t as hard as it seem, they maybe use premade templates and generate content with ai to fill these gabs using a token system i think, if someone knows the exact process i’d like him to help me out because im new to shopify’s developement ecosystem, what sort of apis does they use exactly ? … i will really appreciate
