Thanks for your help. I am simply seeking guidance on having and app whose business model is pay for the client, and allow users to BYOK. Happy to adhere to App Store Guidelines.

I second this — how do we leverage Writing Tools as developers. LIke if someone has a Recipe Title And I want to create a Writing Tools button in my SwiftUI app that is like ( Give Recipe Title a Fun Name! xo ) And then leverage Writing Tools to rewrite the text with the prompt "Rewrite this text in a more playful and fun fashion". Etc. and all the use cases like this.
