Claude AI-Detecting AO3 Site Skin
Hello hello! Some of you have probably seen the info about the Claude-detecting AO3 skin. I find it useful, but the way it was shared didn't suit my needs, so I tied it in with the standard Reversi site skin to make a version that works better for me. I'm sharing it if you want to use it too!
As always, this is an optional tool. You don't have to use it if you don't like it. This is a site skin, so all it does is affect what AO3 looks like on your own account - it doesn't change what your readers see.
This skin looks like Reversi by default. On any fic where it detects a 100% clear snippet of Claude AI generated text, it will light the fic up bright red. Still readable if you wanna keep going, but now you know that fic contains bits of Claude AI.
It does NOT:
Detect other AI, only Claude!
Change anything for other people - just you.
Flag EVERY Claude-generated fic. If the poster took the time to clean up the writing even a little, it will not flag with this tool even if it was written entirely by Claude.
Have false positives. There is no reason for this to light up a fic unless some or all of it was copied and pasted directly from Claude.
Give you a reason to harass people, even if they made a shitty choice to use AI in their fic.
I did not write this CSS myself! The person who discovered/shared this provided a small snippet of code to use to do this, and I just stuck it onto Reversi so I could have a skin that still looks nice. I am choosing not to link directly to the creator's document because that document seems to double as a callout post for various writers, and I'm not big on that. If you really wanna see it, you'll find it with an easy Google search.
