AI apps in high trend all 2024 and I believe 2025.
So had to build some of them. I heard and saw that "AI girlfriend" type of app is getting some hype now, but all of them had content of nudity and sexual.
May be it would be failed road again, but I think it must be more to be friendly and supportive.
That men not require some sexy stuff, but also supportive words, and usually men not really got them.
In Japan common to use "friends rent" service, so may be, in era of online lonliness this kind of app would find it's users.
It should have several built-in personalities, or user can craft it. But at least, user would be able to start app, get some hearwarm and supportive words.
