I also have ADHD-driven blah blah blah. I find achieving brevity laborious, but find LLM results to be unacceptable. A journalism class taught by a well-known professional food critic helped most, but consistently using the free “Hemingway App” editor was almost as beneficial. Blindly following every suggestion pares your writing down to a nub, but it’s great at highlighting sentences you need to rethink without blurring your voice and ideas with bland suggestions.

That's a solid recommendation, thanks. I also did journalism. So I can write succinctly, I just have to put effort in like you. Which is much more than I'm willing to put in after I just wrote a treatise on the human condition to send to the lead developer at 07:30 on Monday.
