Date: February 23, 2026
Host: Jayden Schaefer
Overview
This episode dives into the latest innovations in AI-driven audio, focusing on recent updates from Spotify (AI-generated playlists), Particle (AI-powered podcast summarization), and ElevenLabs (multilingual AI audio for publishing). Host Jayden Schaefer breaks down how AI is reshaping the way we create, curate, and consume audio, discussing both the exciting opportunities and challenges that come with this rapid evolution.
Key Discussion Points & Insights
1. Spotify’s AI-Prompted Playlists
[06:00 – 15:30]
- New Feature Rollout:
Spotify has introduced AI-powered ‘prompted playlists’ for premium subscribers in the UK, Ireland, Australia, Sweden, and previously in the US, Canada, and New Zealand. - How It Works:
Users can generate playlists by typing detailed prompts that specify mood, genre, era, or scenario, e.g., “songs that feel like the final score of a specific movie” or “intros to artists I’d probably love but don’t know.” - Pros:
- Personalization: “You get to customize your algorithm basically and actually think it’s the correct direction.”
[13:05] - Rapid playlist creation without searching through genres and existing playlists.
- Ability to specify for new music or tracks from user’s library.
- Personalization: “You get to customize your algorithm basically and actually think it’s the correct direction.”
- Cons:
- Manual Prompting: “I don’t want to have to be a quote unquote prompt engineer [...] that I gotta copy and paste into Spotify every time I want this new fancy playlist.”
[14:00] - Beta Issues: Caps after 20–30 prompts, possibly to manage costs and gather user data.
- Some creative control lost for playlist curators and indie musicians who use playlists for exposure.
“Doing these AI playlists essentially kind of kills off that entire industry or that entire way of making content.”

- Manual Prompting: “I don’t want to have to be a quote unquote prompt engineer [...] that I gotta copy and paste into Spotify every time I want this new fancy playlist.”
Notable Quote
“As someone that is a playlist creator, or they call them playlist curators, I sometimes get really busy and I don’t update my playlist for a month. And maybe there’s a bunch of great songs that would have been perfect that the Spotify algorithm could have found that I didn’t find.”

2. Particle: AI-Powered Podcast Summarization
[15:31 – 21:20]
- What is Particle?
An AI news app (built by former Twitter engineers) that now treats podcasts as first-class news sources. - Podcast Clips Feature:
The app scans podcasts, extracts notable moments, and aligns those clips with related news stories in the main feed: “Basically what they’re saying is that you shouldn’t have to listen to an entire hour-long episode just to find 45 seconds that actually matter.”
[17:45] - User Value:
- Great for podcast fans who want highlights.
- Especially helpful for time-strapped listeners who want main insights or breaking news.
- Monetization:
Particle offers a freemium plus subscription model: $2.99/month or ~$30/year for full features, including custom summary controls and audio feeds in multiple voices.
Memorable Moment
“It would be sweet to just be able to go and say, like, hey, give me like the five top things that happened, the, you know, the top moments, the things that were said.”
— Jayden Schaefer [18:30]
3. ElevenLabs: Multilingual AI Audio for Publishing & News
[21:21 – 28:50]
- Jayden’s Personal Use:
Jayden shares his deep experience with ElevenLabs:
“I might be getting close to $10,000 of ElevenLabs credits I’ve spent over my life. So obviously, I love this company, but I have a love-hate relationship.”
[22:30] - Key Features:
- Audio dubbing for podcasts into multiple languages (French, Spanish, German, Mandarin, etc.), retaining the original host’s voice.
- Speaker identification and voice cloning for multi-speaker shows.
- Lip-syncing capabilities for dubbing over video, maintaining proper pacing and natural output in the target language.
- Industry Impact:
- Makes podcasts and audio publishing accessible to broader, multilingual audiences.
- Opens new avenues for international listenership and monetization:
“By being able to monetize, go into different languages, you have a lot more monetization opportunities, which I think are really interesting.”
[26:50]
Notable Quote
“Publishers are now turning into audio by default. And then they’re also going to be doing multilingual audio on demand.”
— Jayden Schaefer [27:30]
Major Trends & Takeaways
Convergence of AI & Audio
- Spotify: “Making audio discovery a lot more like chatting with a smart assistant.”
- Particle: “Making podcast audio more like scanning headlines.”

Future Directions
- AI is not just improving convenience — it’s fundamentally changing how we interact with and consume media.
- Next big areas: Conversational, interruptible, and interactive audio experiences; news consumption turning into dynamic dialogue.
- Competitive advantage lies not just in model quality, but “who can come up with the best use cases.”
