Pretty interesting project. I have a special, yet weird, emotional attachment to these HN-based projects because they act like extensions or add-ons that could improve HN in one dimension.

While I don't feel like using this tool when I sit in front of my computer or when starting doom scrolling on my phone, I certainly would like to use it when I need to quickly check HN while being busy.

Some quick feedback:

1. First, regarding the UI/UX:

  - The title and subtitle don't tell much about the app.
  - In the audio track, while you can see the progress of the playing audio, it doesn't show the total time nor the current time.
  - It would be useful to highlight the audio track into segments, each one representing a story.
  - It would make sense to mention how many stories are being summarized (seems to be 5 right now).

2. For a better use case, I believe it would make more sense to have this tool as a mobile app or a PWA to easily access it even from your car's infotainment system while driving.

3. Tightly linked to (2), having this tool as a mobile app and making it available as a widget, with a Play button, would reduce the number taps needed to play the broadcast.

I hope this serves as a constructive critic.
