Audio has always been static, limited, and the same for everyone. SUN makes it personal, dynamic, and always up to date.

Create podcasts, audiobooks, or structured audio experiences on any topic. Customize everything, from length and voice to language. Ask questions at any moment and get answers in real time.

Not sure what to create? SUN knows what to play. Connect the apps you already use, and it continuously adapts to your interests, delivering audio tailored to you.

Built by Artin Bogdanov (Harvard CS), Mehmet Günhan Ertosun (Stanford PhD in AI), and Amy Hua (founding engineer at Amazon Podcasts), SUN combines deep technical expertise with real insight into how people consume audio.
