Hi, not a problem to answer your questions. Yes, it's my work. I have never used AI to write a story and I won't do so. The screenshot is of a word counter app. I write my stories on that because it is part of my challenge to write a story in precisely 50 words (it is the word count that I am interested in). You can check out the Freewriters writing prompt everyday at @daily.prompt (some people write for 5 minutes others write for longer or shorter times). I've been writing on Hive (previously steem) for years so I don't feel I need to add an explanation to my posts. And my 50-word #ZapFic challenge is pretty well known (check out @zapfic.club) and has been going for many years now. edit: I will add a little bit to the end of my posts in future to state that it is my own work and my anti-AI stance on writing and other art work. #NotARobot!
Further edit: I've seen you are a writer. I'm guessing by your question that you may also be anti-AI. You might be interested in a facebook group I'm on (as Bruce Arbuckle) "Writers Against A.I. Writing Support Group" https://www.facebook.com/groups/759974362363357
