I think it’s totally fine to use AI for cover images, especially if you don’t have the money to hire an artist, don’t know anyone who can make one, or just don’t have a cover image at all. A visually appealing cover can make a big difference in grabbing attention, and AI can help fill that gap without requiring extra resources.
That said, I don’t believe AI should be used to create the actual project itself—whether it’s a game, app, or story. AI can be really helpful in guiding you, like showing you how a feature works, pointing out where a button is, or helping you brainstorm ideas—but letting it make the project for you defeats the point.
So, for me, AI shines best as a tool for art support or guidance, not as a replacement for the core creative work.
