I throw my newsletters in a shared folder and use various TTS programs to listen to them as podcasts. Working to cobble together a manual but not particularly intensive process where news letters are aggregated into a podcast with newsletter as transcript with timestamps. Some podcast apps have bookmark/note support which is a bonus, though non are cross platform. Ideal setup is physical button press will highlight current sentence and spit out a summary. I can see a service with some sort of collaboration system especially with improving TTS quality.
