It is a shadow tiddler (and you can access it, or any other shadow, via the shadow tab of the advanced search) but it’s very probable that the AI is also wrong; most of the wikitext snippets I’ve seen from it have been suspect at best. What did you ask it to prompt that response? There’s almost certainly a better/more conventional way to accomplish whatever you were trying do.
I would be very careful with ChatGPT. We are beginning to understand it does make things up that do look plausible. For example, if you ask it to create a bibliography on a specific topic it writes its own book/journal/article titles but then attaches them to real people who are authorities in the chosen subject area!
I may do a post on chat GPT and tiddlywiki but if it gives you code in its answer it may be totaly wrong. I saw it nixing wiki text with python, in other words Rubish.
