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.
I am currently trying it out right now! It is a really fun product concept. Something that I was reaching for almost immediately was a transcript or captions though. I am not sure if there is a setting available currently that I am missing.
I was planning to go through a few different 15 minute lessons to see what kind of different lesson structures it builds.
@prebuildlabs Thanks for trying it out! You’re right, captions or transcripts aren’t available just yet, but it’s something we’re planning to add soon. Appreciate the feedback!

Hey Product Hunt! 🎉
I'm Artin, co-founder and CEO of Sun, an intelligent audio app for curious minds eager to learn something new every day in an immersive, audio-first way.
⭐️ The founding story
We're a team of eager learners who live inside audiobooks, podcasts, and research papers. But today's audio isn't designed for people like us. Or like you. It's the same for everyone, same format, same pace, same assumptions about who you are and what you need.
You have a favorite AI, favorite sources, a life schedule that's uniquely yours, a way of thinking no one else shares, and a life that couldn't pause for decision paralysis when browsing to decide what to listen to next.
Sun is built around that reality.
⭐️ What's live today
🪄 Generate whatever you want to listen to, just by speaking to Sun. Type a topic, ask a question, follow a rabbit hole, Sun turns it into a crisp, engaging audio lesson in seconds. No searching, no scrolling, no settling. If you can think it, Sun can teach it.
🤖 Your favorite AI integration Sun's users are mostly AI enthusiasts, so we leaned in. Sun learns about you through the AI you already love. Just copy a prompt that works best with Sun, paste the response from ChatGPT, Claude, Gemini, whatever you use, and Sun builds your learning profile your way.
🎧 Audio Flows Think audio TikTok. One tap starts an endless, personalized stream of bite-sized audio lessons. Each one flows into the next, built around your interests, your level, your curiosity. It's the easiest way to learn something new without even trying.
💬 AI conversation

⭐️ A final note
Our dream is a world where in-context learning, delivered through the healthiest medium, audio, drives continuous growth for everyone, every day. We'd love every curious mind in the PH community to join us and help make this real. Try Sun today with invite code PHFRIENDS and share your feedback.
PS: A huge shoutout to our beta users. We wouldn't be here without you. 🙏

@artinbogdanov Love the idea guys, keep it up 👋💨
SUN
@tonnoz Appreciate support Tonino!
minimalist phone: creating folders
Interesting. I see a little overlap with Shazam – is there any possibility to find music that way too and then customise it accordingly?
@busmark_w_nika Thanks for the question! Right now, SUN focuses on non-fiction audio, like podcasts, courses, and audiobooks for curious learners. Music isn’t part of the experience yet, but we love the idea and might explore it in the future, since music is such a big and fun part of audio!
SUN
@busmark_w_nika We generate and deliver spoken audio like podcasts, audiobooks, and audio experiences, created specifically for you.
InsForge
Really like what I'm seeing so far. My only question is how it handles depth over time. First lesson felt like a solid intro but I want to know if it gets harder as it learns about me.
SUN
Hi @jiaqichen , first of all, thank you for giving it a try. Personalization and adaptive learning are our top priorities for upcoming releases. The promise of SUN goes beyond a single session. We want you to get real value from every lesson and interaction, while SUN continuously learns about you as you explore each topic. I’d love to hear your feedback and learn how we can make SUN the perfect audio experience companion for you.
This is a nice direction turning learning into something you can just listen to fits really well into daily life curious how personalised the experience feels over time as you use it more
@simon_clarkson So glad our mission resonates with you! We actually had a slogan: “Learn while you live your life.” SUN constantly learns about your preferences and emerging context, adapting as you go. Can’t wait for you to try it and see how it evolves!
SUN
@simon_clarkson Thank you, Simon. Excited to get you feedback.
Interesting! Much needed concept, but how it is different from notebookLM?? There I can generate podcast, notes and quiz etc.
SUN
@lak7 Responded to this question below. Here's the copy of my response:
"
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.

@artinbogdanov Interesting! Just gave it a try and it's preety cool, although it would be cool if there is an option to choose different styles like feynman, deep dive or storytelling etc. Or should I add that in prompt itself?
Great idea! Was just thinking about this, but for the content creators I've subscribed to through SRS, would be lovely if this becomes supported someday (e.g., RSS integration that turns your subscribed articles to podcast, like what's jellypod is aiming to do: https://www.reddit.com/r/rss/s/Y...)
Nevertheless, cool idea!
@odyash Oh we love this idea! RSS → audio is such a natural fit. Adding it to our roadmap!
And appreciate the kind words, glad it resonates
