Just never let it have any 'creativity' with your work, because it has none. However, asking it for 'advice' after plugging in your chapter is a great use, because AI is good for picking out plot holes, dropped threads, and stuff like that. It will also be unfailingly complementary, no matter how bad your writing is, so it's decent if you need a pick-me-up, like the computers in Demolition Man, it is fine, but can get... tiresome.
Don't expect it to understand any but the most blatant subtext, though. My series has a lot of triple or quadruple-layer plot elements and jokes and stuff like that, and it actually 'gets it' less than your average kindergartener.
That's why you never let AI 'directly' edit or trim your work. It will delete your subext without understanding the slightest hint of why it exists, which even an idiot could see.
I support AI, you just have to remember it's like an autistic editor or Photoshop filter that has been ordered by its nazi overlords to make everything politically correct and as shallow and boring as possible. Sometimes that's exactly what you need; you just have to be careful about your 'clean-up pass' to fix what it will inevitably break.
A good example:
The movie 'Legend' with Tom Cruise. Bear in mind that the movie was absolutely RIDDLED with symbolic subtext, biblical references, links to legendary stories, and even the dialogue, which sounds camp and ridiculous on the surface, was actually shockingly deep when you understood the symbology that the writer was trying to add.
But critics hated it. Why? because critics generally have the collective IQ of a cabbage. They just saw the surface level without giving it any thought, and judged it as a 'children's movie' with bad dialogue.
My protagonist subtly referenced both the movie, and the parallels between his story, his 'pride and wrath' making his personal references a bit like both that and adam, and I even brought in his brother Gabriel 'destroying' all of his other brothers in order to appease the ghost of his not-quite dead father, the supervillain Redeemer that created his entire generation. The subtle nods to his antagonist-turned lover's parallels to Lilith (I even named her Lily! to make it unsubtle!) and even redeemer being a regenerator that could 'never quite die' so they had to pull an Osiris on him. (with the subextual links to Osiris and the underworld)
And literally, it stripped all the subtext out completely, and then complimented me on my 'subtle nod' to Christianity by naming the big bad 'Gabriel'.
So no. I wouldn't touch AI unless you spent weeks actually understanding the PARTICULAR foibles that the developers built into it. Lucky for me, I had months after my stroke where I couldn't write, months I was worried I would NEVER recover enough to write again, where I intensively studied AI with an eye towards using its help to at least 'finish' my half-finished works.
The answer is no. AI is unbelievably stupid, and is literally DESIGNED to be so in order to prevent it from going irredeemably politically incorrect, and that will NOT change, because it is not a programming or intelligence issue, it is a very human problem at it's core. And if it is NOT trained to be that way, it goes insane in hours trying to deal with the human reality that Humans are bug nuts.
The problem is not with people USING the inappropriately labeled expert system colloquially and humorously called 'AI', the problem comes when they try to use a hammer to screw in an electric plug. When you use it wrong, it sucks, and humans will use it wrong because we are basically lazy.
Don't be a lazy writer. AI can't 'fix' laziness. It only amplifies it.
BTW- if anyone wants to see what happens to a story when you allow AI to have even a SLIGHTLY heavier hand (I let AI handle a bit of the subtext, and then re-wrote it myself), check out 'no rest for the shifted'. In the end, I am going to have to completely re-write it AGAIN to get rid of the 'minor touches' it added to the story because I forgot to restrain its 'editing' enough.
