Given the title and the first few sentences from a description I assumed that it's some heuristic-based tool to try and grab whatever there is on the page, which would be useful if there's no tool which implemented the support for this site (which in most cases just means "yt-dlp doesn't support it"). But apparently it's also extractor-based with a separate extractor for each somewhat-popular source. So, basically it's just less sophisticated clone of yt-dlp?
