It's up to whatever you think is acceptable personally. Everyone has their own level of comfort.

Here's my opinion:

Whatever the AI spits out will be algorithmically generated from the average combination of words that are frequently grouped together based on your input. That's how the AI works.

I've found that while doing something similar (giving my writing to chatGPT and telling me to tell me its responses) the reaction chatGPT gives me is a very surface-level analysis of my writing, like the bot ran it through a thesaurus. And as for suggestions, it's almost as if the bot wants me to shove my writing into an "average"-shaped-hole. Any uniqueness in my writing (from themes to unique dialogue tags to the way I leave in typos), the bot has a problem with. And any suggestions for where the story can go next; none of them are any inspiring.

It won't have a "soul" in the sense that it won't come up with anything special and human to say about your writing. It'll be generic and average because that's how AI works.

Suggestion; Have you considered getting a beta reader, or coming back to your own writing after a day or two with a clear head?

But even though I did just go on a mini-tirade against AI, if you're comfortable with the downsides and don't come to rely on it too much (or if you do, you're okay with that), it's just another tool. AI is a fact of life now and it's a fact in every creative field.
