I have much more time to listen to content than to read content. My suggestion is to partner with news aggregators such as Feedly or newspaper apps to add written articles to the Podcast Addict playlist to be played as audio via text-to-speech.

The way I envision this working is that in the news aggregator app when I'm looking at the preview of an article, next to the button to open the article to read it in a browser there would be a button to "Send to Podcast Addict" and a text-to-speech version of the article would be added to my Podcast Addict playlist.
