Create podcast-style briefings from the ideas you follow.
Last updated: May 2026
Synthesis Radio is the Premium layer for listeners who want a generated briefing around podcast topics, saved ideas, and listening context.
Useful, specific, and tied to the app.
From scattered episodes to one briefing
Bring related ideas together when a topic spans multiple shows and long conversations.
Designed for repeat listeners
Use it when your podcast habit is also a research, learning, or professional workflow.
Inside the podcast app
Keep the generated briefing connected to the player, Brain, transcript context, and episode links.
How this works inside The Podcast App.
The practical boundary is simple: free core listening comes first, Premium limits stay clear, and advanced features depend on eligible podcast data.
Start with listening history
Synthesis Radio is framed around the listener's own eligible source material, not generic web search. The app needs enough repeated, well-supported context from episodes and transcripts before a briefing is defensible.
Generate only inside Premium
Creation belongs to Premium because it depends on deeper AI processing, source evidence, and higher limits. Free users still get the core player and limited transcript-backed episode chat.
Keep citations central
The conversion promise is not a detached AI podcast. It is a cited audio-style briefing that can point back to the shows, episodes, claims, and ideas that produced the synthesis.
