someone on twitter figured out how to make an ao3 site skin to show if someone used ai (specifically claude, and specifically copy-pasted into the fic without being put in a word doc or something first, but still better than nothing) and i am delivering this information to YOU!
step 1. go here (create new site skin page). (if you don't have an ao3 account you'll need to make one. i promise it is so so so easy and you'll get to read a bunch of member-locked fics u didn't know existed)
step 2. copy paste this:
body:has(.userstuff p.font-claude-response-body) #outer, body:has(.userstuff p.font-claude-response-body) #main, body:has(.userstuff p.font-claude-response-body) .userstuff, body:has(.userstuff p.font-claude-response-body) .userstuff p, body:has(.userstuff p.font-claude-response-body) .userstuff div { background: #ff0000 !important; color: #ffffff !important; }
in the css box, name it whatever u want, and, if you are NOT using a site skin already, click submit.
if you ARE using a site skin already, click "show advanced" (takes your hand. i will protect you. i promise). click the box next to "parent only." now click submit, and then click use :-)
step 3. if you're already using a site skin, find it and click edit. scroll down to "parent skins" and add the one you just made. click update.
now if you click on a fic where the author copy-pasted claude directly into the work text box, the whole screen will turn bright red 👍 (or, if you go into the skin you just made and change #ff0000 to another hex code, it can be whatever color u want) (the world is your oyster. go my scallops). you might need to click show entire work if that's not ur default setting in case claude was used in later chapters but not the first, too
edit since i forgot to add how it works: it doesn’t look for typical “ai tells” at all, instead it searches the code for “font-claude-response-body” in the source code, which is why it only knows something’s ai if it was copy-pasted directly from claude! i’m not sure if there’s similar code for other llms and i’m not sure how i’d find out but i’m glad there’s at least one way to tell if something wasn’t fully human-made
