How do you prevent plagiarism.

Since AI scrapes the Internet, there is nothing that it is regurgitating that is original. I just used Perplexity to write a 2000 word article, and it added a citation for every page that it scraped. There were a dozen different sources.

I know about plagiarism checkers, but what do you all do in terms of citations or footnotes so that you are attributing an original idea to its creator?
