Pretty basic ones, I got into AI images cause of that viral AI avatars thing that levelsio made 2-3 years back and have just been iterating on that idea(even though I think if I went into the AI text side of things, I'd have been much bigger at this point):

https://admakeai.com - Recently got this to 800 MRR , kinda trying to make it the main thing since the LTV on it is the highest. So if I could just figure out ads, this has the highest potential

https://aieasypic.com - First project that I made that made money from subs vs making money from ads, whole reason I continued to indiehack. Its kinda dying but core users still bring in 3-4k/mo , altho actual MRR is 1k/mo

https://bestphoto.ai - Made this after I got frustrated from the bad decisions I made on above, basically a tech rewrite + clone + simplification of aieasypic. Currently makes the most but at a lower margin than aieasypic. Not gonna say exact numbers, but lets say 5k+/mo
