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.

Happy launch day! Used PHFRIENDS. First lesson was great. Already thinking about what to ask next.
@nate007 Glad to hear! Happy listening!
I've got many podcast episodes and audio books saved that I'll never listen to. This is the fix.
@chan1108 Turning “I’ll get to it someday” into something you actually listen to. Glad it resonates!

The AI profile idea is genius. Does it continuously update as I use the app or is it a one-time setup?
People often ask: how is SUN different from NotebookLM? Here’s the scoop 😎
Tool integrations — we connect with your favorite tools (like note-taking apps), so your knowledge flows in automatically. No manual uploads, no hassle!
Learns about you — SUN actually understands your context and proactively generates personalized audio content just for you. 🪄
Community-curated content — beyond your own stuff, you get access to high-quality content from the community. Learn from the best!
Audio-first experience — SUN isn’t just analysis. Think podcasts, courses, and audiobooks — all ready to listen anytime. 🎧
In short: less uploading, more learning, all audio, all personalized. ☀️

Wow! I’m more of an auditory learner, and your concept really resonates with me. Congrats on the launch, I’ll definitely give it a try!

@a_hryshchenia Thank you, Ana. Looking forward to getting your feedback.
This feels like a much better alternative to my brain rotting on tiktok!
