I have a lot of AI writing on this site, possibly more than anyone except for people who aren’t openly revealing they’re doing it. The other really long AI series was deleted by the author, who was using a second account to post it. So it’s an important issue to me. I find the “assistance” of AI tools pretty useful for reasons of time, almost never getting stuck (except in areas that the AI is bad at) and so forth. It still does take plenty of work to edit and improve the quality of AI writing, but it still saves time — I am better at editing than first-drafting — and I’m happy with the quality. I don’t have any interest in saving time by writing fanfic. I already got the method I use, which is more than 50% human, approved by Tony as fitting the rules of the site.
Here are my thoughts about the feature request: sure, it’s a good idea, although I think it’s better as a content warning. “AI-Human Written” or “AI Assisted” makes sense since any story that’s more than 50% AI-generated is not allowed on the site anyway. This is easy for me to say, since I put the same thing in the description of all my series, and it saves room in my descriptions to have a tag or content warning! I don’t really want anyone not realizing it’s AI-assisted and getting upset, and so far this hasn’t happened.
However, I don’t know how many people will use that tag or content warning. Some people are using AI on this site and not mentioning it, right. Besides, what counts? If you use it as a brainstorming tool to come up with plot ideas, is that AI Assisted? How about having a tool like Grammarly or Quillbot rewrite some sentences? Many sentences?
I understand why some people wouldn’t use this tag, because some AI writing is very hard to detect, especially if edited. Because I do make it clear that I use AI tools, I do get comments from people who say “I could tell this was AI-written.” Sometimes they’re wrong, I’ve gotten that comment about chapters or quotes that were 100% written by human, LOL. Sometimes awkward or stilted writing is the human’s fault! So, by using a tag you’re going to activate people’s preconceptions and ideas of how AI writing works. Everyone thinks that all AI tools work like ChatGPT, for instance — you just put in a prompt like “write an isekai story about Mineta from MHA but gender-swapped” and it pops out a bunch of paragraphs. That’s just the simplest, low-effort, and usually poor-quality (samey) way of using AI.
As for copyright, the US Copyright Office made it clear that anything a human adds to an AI-created work is copyrighted, but the AI-created parts are not. My works, for instance, mix the two together. Most AI sentences have at least a bit human interference and are interspersed with human-written sentences… so it would be hard for anyone to only identify or pull out the “un-copyrighted parts” to use in the public domain. (I have the record of which is which, but it’s only readable in the original writing tool.)
