The genre is dystopian science fiction, but not hard scifi, nor using many weird words and names.
I did it with ChatGPT, but I wonder if there are better, specialized tools out there. I also tried DeepL, but they accept credit cards from Brazil in their pro version (which I need because the text is 25,000 characters long).
Thanks
[more seriously... "fiction" is a big bucket. I suspect that none are great, but some might be better at westerns or romances than others. Narrowing it down might yield better results.]
