Raphael AI lets you create new images or change existing ones simply by describing what you want. Instead of learning complex editing tools, you write an instruction and the AI applies it, which also works for remixing a picture in a new direction.
The site says it is powered by Nano Banana Pro and GPT Image 2.5, and it can keep the same character looking consistent across several images. Signing up gives you free credits, and there is a prompt library to help you get started.
