Launched this week
SUN turns any topic into a personalized AI generated audio course you can listen to while living your life. Instead of static libraries, users create interactive courses on demand, ask questions during playback, and learn hands free during commutes, walks, or workouts. Built for continuous, screen free learning that fits naturally into daily routines.
Looks promising, congrats guys! How is it different than NotebookLLM audio generation?
SUN
@farbodsaraf great question. Here’s how SUN is fundamentally different:
No dataset required
You don’t need PDFs, notes, or existing content. Just describe what you want, and SUN creates it instantly.
You don’t need to know what to ask
Most people don’t wake up knowing exactly what they need. SUN proactively surfaces what’s relevant based on your behavior, goals, and interests.
Fully customizable experience
Control duration, depth, voice, language, and structure. It adapts to you, not the other way around.
Continuous, not one-off
SUN isn’t a single session. Every interaction builds on the last, creating a compounding, personalized stream over time.
Built for real life
Designed for moments that usually go unused. Commuting, walking, working out. It fits seamlessly into your day.
Community layer
Discover what others are generating, what’s trending, and explore beyond your own prompts.
Integrations
Connect tools like Plaud. SUN turns your captured content into structured audio experiences and recommendations.
Hybrid content model
Not everything is generated. SUN can also surface high-signal snippets from original content when it adds value.
In short, you don’t search for content. You generate it, and over time, it starts generating itself for you.

Is there a way to set lesson length? Sometimes I have 5 minutes, sometimes 20. Would love that control.
SUN
@kate_ramakaieva Yes, you can set whatever duration you want. :)
Really like the concept and the first lesson was great. My only question is whether it gets deeper over time or stays at the same introductory level. Hoping it learns fast.
@shijun_liu yes, SUN is designed to adapt depth based on you!
Just downloaded. Is there a way to save lessons I like? Heard something interesting and wanted to bookmark it but couldn't find the option.
@jennyxxie thanks for trying SUN, Jenny! 🙏 Right now, bookmarking/saving lessons isn’t fully built out yet (you’re not missing anything). We’ve heard this request a lot, and it’s high on our roadmap!
Looks interesting! How does this compare to NotebookLM? The key difference I see is that NotebookLM needs your own documents as a source. Does SUN generate content entirely from scratch on any topic, with no input material needed?
@sophiafyi Exactly! NotebookLM works only with your own documents, while SUN generates structured audio on any topic from scratch, no uploads needed!

Seems an interesting idea.
As I went through comments I read SUN doesn't take any inputs like PDFs or any info, we just have to describe.
So I believe the text for the audio is LLM generated? So how the output looks like? Is it dictated as it is? Or is continuous back n forth regarding context is done so that the info for the actually relevant to what user wants? As the depth or specific context to any topic is imp.
Would love to understand!
@sujit_jaunjal You’re right, SUN doesn’t take PDFs or external files directly yet, so the audio content starts from what you describe. But the magic is in how it adapts as you interact. The audio is LLM-generated, yes, and it’s not static. You can pause, ask questions, or dive deeper on any point!

@amy_wenyan_hua got it👍🏻

How does Sun handle accuracy on topics like health or investing? I'd actually use it for those and want to trust what I'm hearing.
SUN
@eeeeeach Great question. For sensitive topics like health and investing, SUN applies multiple layers of validation before finalizing content, including cross-model verification and grounding in reliable sources.
