What AI photo generator is everyone using?

I've noticed that there seems to be a buzz around a certain AI photo generator lately. Could you tell me which one everyone is using? Is it a new player in the market, or has it been around for a while? What sets this particular AI photo generator apart from the others? And how does it work? Is it user-friendly, or do you need a certain level of technical expertise to get the most out of it? I'm really curious to learn more about this tool and see if it could be useful for my own projects or business.
