Then how do you think I should go with it? I can't really post a rough draft cause honestly it's horrendous.
We all have different levels of skill, to improve you don't need AI, you need to read and write.
Here is a exercise you could do;
Look at some of the stories you enjoyed reading before and see how those authours wrote it, not the story but the lay out, the delivery, and note it down. What did they do to make their story appeal to you? How did they word their sentences? Build their paragraphs? Manage dialogue? Basically how did they present the reader all the exposition that you say is in your rough draft that isnt presentable as is.
Take that info down, and then look at whatever you wrote.
Can you see how your information could fit into a similar format? Or can you manipulate what you wrote to be like that.
Try it, make your work look (physically, not content) like something you enjoyed reading.
In the end, you will only improve with practice. Write some short stories, write some background information on your characters, always trying to improve how you present that information. In the end, you could have a mediocre work, but if it is presented well, you will probably get good reviews, while a great story presented as a brick of text will probably get dropped.
My opinion anyways, take it with a grain of salt. I am just loafing around the forums instead of writing my next chapter like I should.
