Out of curiosity, I filtered the Visual Novel genre by AI-generated. Many of the games that popped up have art that does not seem AI-generated at all. Nor does the creator or the comments mention anything about AI.
If these games have art made with AI, then AI is much better at emulating digital art then I thought. How did itch.io determine that these games were made with AI? Does the AI-generated tag remain even if AI assets were removed?
