OP here, thanks for this feedback, my workflow was to first have a draft and then feed it into a LLM to fix grammar and improve conciseness. Wished there was a tool (I think folks are already working on) that is similar to what a book editor does which suggests changes as opposed to changing the styling.

You can simply ask the model to point out if there are any problems and then fix them yourself. You don't have to copy and paste its output into your book. You can also pay for an actual copyeditor to edit your book.

If it is only to fix grammar and improve conciseness, I find grammarly quite useful. AI goes way beyond these things. Also, while making something concise, AI might make things more difficult for the readers to understand. Worse, it might write something that is totally wrong.

Perhaps this is what you are looking for: https://www.deepl.com/en/write

It corrects spelling errors and improves awkward wording. You can then go and choose alternative sentences or words. Just don't expect any sort of deeper intelligence.

The workflow is fine, the content is fine. The LLM needs to lean in a little harder on your voice and condensing your content— focus on subtraction rather than addition.

The problem is: viewed as a one-off, it’s a gem. But put it on the AI slop conveyor many commenters here apparently are fed all day long, the voice is too similar, it seems like another chapter in that anthology.

Hiring a fairly competent editor is affordable (sometimes even cheap). Specially now that a lot of the commercial copywriting has taken a hit with the ai slop
