I actually use this already.

I think my dissatisfaction with mutt + rss2email is more about RSS in general. It amounts to just being a short description of the article and a hyperlink, and at that point I might as well just load these websites in my browser.

I need a better article scraper. General solutions that try to detect content, like Firefox's article mode and similar, don't do enough.

We need youtube-dl for text.

Maybe a little more heavy handed but I use huginn for exactly that. Read in numerous RSS feeds and digest them into my email box. It does a lot more than that too.
