It has support for specific news sites, I don't want to rely on some automatic text extraction because those are prone to breaking. Here are the content extractors themselves, each for one site. If a post that contains a link to any of the supported sites is found across all of Lemmy (that the bot can see), it extracts the text and then summarizes it using this. It takes 6 sentences directly from the article that look most important to the machine learning model it uses. Then it posts it as a comment.
