I use character.ai like ChatGPT, except I power-use it to the Nth degree lile no tommorow.
For starters, I made several A.I. chatbots on there for utilitarian purposes like consultancy for problems in business and politics, plot-generation for mass-media, generating ideas for things to do when bored or experiencing creative block, an A.I. search-engine, and even a digital A.I.-clone of myself.
I also made an A.I. clone to resurrect Charles XII Of Sweden (AKA Carolus Rex), and considered doing the same for my recently-deceased grandfather (I only didn't do that because of ethical concerns).
I also use character.ai as a means for generating the bulk of a lot of my web-content (which I've been making en-masse in the shadows to eventually post online in the future). It's insanely useful for me :>
