AI tool that makes AI generated photos natural

Usage example:
Some time ago I used AI, which generated a nice image for me, but it had a lot of strange distortions and unnecessary, even stranger elements.
In that case, I would like to upload a photo and use a prompt and or a selection on the image to ask the AI to correct these elements.
tldr; AI that corrects AI-generated images so that they do not look as if they were generated by AI
