Q: I entered the text I want to show in my image, but it’s not working?

​A: It’s important to note that generative AI for image creation, in general, struggles with accurately rendering text. Due to the nature of the technology, ensuring correct spelling and alignment is challenging. Consequently, it’s recommended to avoid incorporating text into generated images to prevent potential inaccuracies. Please understand that this limitation is inherent to the generative AI model utilized, over which we have no direct control.
