Synthesis Radio: one topic, across your shows

In the app it's called Crosstalk, and you find it in Podcast Brain.

What you get

A radio-style episode on one idea, traced through the shows you follow. You hear the original speakers in their own words, in clips, with short narration in between that explains how they connect and where they disagree. It plays in the regular player, and once it's made you can listen to it offline.

How to make one

1. Sign in. Crosstalk needs an account, because it reads your listening history.
2. Open Podcast Brain and tap Crosstalk. Choose a topic, or tap Make one for me.
3. Or start from an idea in Brain: tap Crosstalk this, or Hear both sides in a Crosstalk.
4. Wait a few minutes. The app finds the relevant moments, writes the narration and assembles the audio. You get a notification when it's ready, and playback can start before the last segments are done.

What it needs

It works from episodes you've listened to that have transcripts. If your shows haven't covered a topic enough yet, the app says so; try a broader topic, or come back after more listening.

Free and Premium

Crosstalk is free up to a daily limit. Premium ($4.99/month) raises the limit. More on what Brain can do: transcripts, episode chat and Podcast Brain.
