Not exactly a new idea, but as a fun side project, I built an AI photo generator (i.e., an SD/FLUX wrapper) https://www.photovortex.com which has crossed $500MRR last month.
I also just launched a spin-off of it, https://www.portrayya.com which is more focused on generating a set of portraits of a single person (i.e. headshots for linkedin etc.) instead of prompting individual images.
Overall this is a very crowded space now because it's so easy to build, but there is still a learning curve around landing page design, conversion, ads etc. and potentially some niches to explore.
