@bbhusari I disagree with this, you can do creative work with AI. Creativity and AI are not mutually exclusive… IMO generating quality content will become an art form in of it self. JMO 
My specific focus is around technical writing but there’s a lot of overlap. The reason to leverage AI in technical writing is that technical documentation often becomes stale and out of date shortly after it’s written. The SDK changes, new features are introduced, a button moves to a different screen, etc.
We use humans to do the vast majority of technical writing currently and they can’t keep up. They’re overwhelmed. It’s a thankless job and you’re always behind. AI has the potential to revolutionize technical writing tasks.
I don’t think the benefited can or should be limited to just technical writing tasks. Video games is one example of an area where solid creative writing skills would be appreciated. There’s simply too much dialog in a video game to have humans write everything and do a good job. I’m sure there are other scenarios.
That is something SPECIAL! 
But you are still going to need an editor to read every word and every bit of code to confirm it’s not bugged and/or hallucinated?
Yes of course human oversight will always be needed but with this tech what was once redoing a whole book for a few changes is a much simpler process. AI is not a cure all, it just makes the process smoother. We all use AI in work right?
You just need to set it up differently. Either as a project or inside a community builder GPT. I usually do it by giving it a personality disorder kind of. I tell it to not act or take on a role and always be the one talking to me. The split itself in to additional personas. In your case it would split itself into each of the characters you have and tell it they can interact with each-other but they can never overstep their boundaries and influence each-others characteristics. The main gpt that you gave the instruction to should maintain itself seperate and only speak on behalf of the charaters and never take their personality on as its own.
if you dont want it with the writing you can leave it at that but then just share your writing with it and ask if the chracter agree with what you made them say or so in your story.
In my case i do music for social content so i have created ai artists that the gpt writes songs for. whatever concept i have i share with it and specify what persona its for and it helps adapting the lyrics for that personas vocals, music style and performance. If im down in imagination it can also suggest things based on the chracter. Its truly helpful when you write for different purpuses since my personal taste needs adapt depending on what i need the music for so this help me as well as the ai from avoiding generic writing.
You can make it write not generic by teaching it whatever rules you yourself follow. Give it writing samples to store and then have it give you the same thing written three different ways for you to choose the option you like best. That way it can fine tune itself to your style instead if what its trained on by default. Once i did that any text i run a check on for ai artifacts passes as original without a doubt even before i do my manual edits to it.
Lastly if you use it for a lotnof different writing projects that has different storylines and chracters its best to turn off any function that let it refrences past conversations. If the function is on it will borrow things it shouldnt and influence across projects. When i had the function turned on once it ended up writing a song about one if my other interactions essentially.
If you use AI as an editing tool to analyze POV, grammar, flow and sentence structure, it can help. But if you ask AI to create a story, you’ll get word associated slop.
