Article creator - Use filename instead of keyword to insert content

1. The problem

Can you give me the variable or macro for existing articles that allows me to base the keywords on the filename please.

If I want to add content for existing articles based on the filename (it could be an insert that people also ask request or a YouTube video related to the filename).

I have some texts in a folder and I’d like to enhance them with content I’ve found on the Internet.

But I don’t have any keywords, so I want to use the file name (which is usually a keyword) to scrape content related.
