just wilmon things

I didn't write the checker and have no involvement with that.

What the tool linked above can say:

This fic includes content that was directly copied from Claude into the ao3 post box

What it can't say:

How much of the fic is ai

What the ai was used for

Reiterating that it only finds Claude fragments so that means that the checker:

Doesn't know if another ai was used

Doesn't know if Claude was used and the copy from Claude feature was used

Doesn't know if content comes from Claude but was first pasted into another document first

Here's some scenarios where ONLY ONE Claude fragment would be detected:

Person goes into Claude, asks it to generate 20k words of a college au meet cute fic. Person pastes the text directly into ao3. One ping

Person asks Claude to generate text that would make their pre-written text look like a tweet, copies that into the ao3 box. One ping 

Person uses Claude as a spellchecker and copies the output into the ao3 box. One ping 

Scenario where Claude ai checker would ping more than once:

Person pastes a paragraph into Claude and asks it to rewrite it more smoothly, copies that into ao3, then does that again

Frequency of code fragment does not equal quantity of ai usage.

Here's a scenario where the Claude fragment ai checker would not detect ai even when that person was using Claude:

Person asks Claude to write their entire fic but then copies it into a Google doc before pasting it into ao3

More does not mean more. This is a binary check of “has fragment or does not have fragment.” 

and GOING FORWARD, because this is such a simple and distinct marker, I expect that no future Claude AI fic will include this marker. It is trivial to remove it. So this is not a preventative future checker. What this IS good for is to read flagged fic and hone a personal sense of what an AI fic reads like.
