You keep hearing a topic
A cluster starts to emerge across multiple podcasts, guests, or perspectives.
Premium generated deep dives

Topic: space policy after 7 episodes
Synthesis Radio turns recurring listening into a focused audio-style briefing you can revisit later.
How it fits
Synthesis Radio is for patterns, not one-off moments.
Brain pulls it together
The product can use the history you already built instead of acting like each episode lives in isolation. The core listening layer still begins with the offline podcast player.
You get a cleaner recap
The result is a briefing-style output that matches the medium better than a plain text wall.
Made for recurring topics
When a subject keeps showing up across different shows, Synthesis Radio pulls the thread together into one clearer narrative.
- Makes long-running topics easier to retain.
- Feels native to podcasts, not pasted from a chatbot.
- Extends listening instead of replacing it.
Audio is the medium
The format matches the medium: structured, paced, and easier to absorb than a wall of text.
Still optional
Synthesis Radio is part of Premium for listeners who want deeper synthesis after the episode ends. If you are still evaluating the app itself, start with the player page or the switch guide.
- The player works without it.
- Premium makes it available when it becomes useful.
- That keeps the main app trustworthy for normal listeners.

FAQ
Common questions about Synthesis Radio.
What is Synthesis Radio?
Synthesis Radio is a Premium feature in The Podcast App that generates guided, audio-style deep dives from the topics you keep hearing across your subscriptions. Instead of reading a text summary, you get a structured briefing built from your actual listening history.
How does Synthesis Radio work?
As you listen, Podcast Brain tracks recurring themes and topics across episodes. When a subject appears enough times, Synthesis Radio can generate a focused briefing that ties those threads together into a coherent narrative — using what you actually heard as the source material.
Is Synthesis Radio free?
Synthesis Radio is part of the Premium subscription, available at $4.99/month or $14.99/year. The core podcast player — offline downloads, queue control, chapters, CarPlay, and more — is completely free with no ads.
Does Synthesis Radio work on both iPhone and Android?
Yes. The Podcast App is available on both iOS and Android, and Synthesis Radio is available on both platforms as part of the Premium subscription.
How is Synthesis Radio different from a regular AI summary?
Most AI summaries operate on a single episode in isolation. Synthesis Radio is built from your personal listening history — it draws on patterns across multiple episodes and shows you have actually heard, so the output reflects your specific knowledge base rather than a generic overview.
