I hope it goes without saying that I have not used AI to write any of my work, but just in case, I have not. BUT, I used AI to help me with the synopsis that Fiction Factory requires in their First Chapter contest. I did not submit my original writing to it ("it" being ChatGPT), but I did let it lead me through a Q&A, after which it produced a very useful synopsis. I changed a few things afterward and used it. At that point, it became a brilliant synopsis, tailored to both the Fiction Factory requirements AND its history of successful authors. Writing a synopsis is a lot different from writing the work itself and is difficult in a different way. This is just to let you know what I did. YMMV.
