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.

How do I ensure that the content that I'm consuming from Sun is not hallucinated content? Are there ways to customize it so that it only pulls sources from a pre-approved list?
making your lesson or targeted subject to learn as an audio is very useful and also flexible for a person who can't study by reading or watching
i liked the idea this app will be in my favorite mobile screen
Nice Artin! IT's super cool how everybody can be a content creator currently because of tools like Sun. Barrier in no longer the technology. If you know something about a field, you can easily do it now. Glad to see you helping on this!!
Does the personalization kick in immediately or does it need a few sessions to calibrate? Asking because my first Audio Flow felt a little broad.
Does Sun surface what I should learn next based on what I've already heard? That recommendation layer would be really powerful.
The AI profile idea is genius. Does it continuously update as I use the app or is it a one-time setup?
Interesting. How does it manage the context of the user? If I use Sun for, let's say, multiple years, wouldn't the overflowing context from past not distort my interest of now?
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.
I have a 35 minute commute each way and I've been wasting it on music I've heard a thousand times. Just tried Sun for the first time today and I think my commute problem is solved.
The best thing is that anything you want "SUN IT". But can you help me to understand how it is different from any other chatbots who just converts scripts into voice.
this is exactly how i want to consume content during commutes :) one thing i'd love to see: a way to "highlight" moments while listening, like tap to bookmark a key point so you can revisit it later without having to skim back through the whole thing
I've got many podcast episodes and audio books saved that I'll never listen to. This is the fix.
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!
Happy launch day! Used PHFRIENDS. First lesson was great. Already thinking about what to ask next.
Interesting! Much needed concept, but how it is different from notebookLM?? There I can generate podcast, notes and quiz etc.
