Ever wish there was a radio station dedicated to the Maillard reaction, beach agate hunting in Northern California, or natural hydrogen production? Narrowcast is a streaming radio service that produces deep-dive audio segments on topics too niche for traditional media. A multi-agent AI pipeline researches each topic across the web, writes an engaging script, fact-checks it, and produces the final audio - making it viable to cover subjects that couldn't justify the cost of human production.





Hey Product Hunt! I'm Aaron, builder of NarrowCast.fm. Long time listener, first time caller - this is my first launch on Product Hunt.
I built NarrowCast for myself, but realized that opening it up to the diverse interests of others would make it much more engaging.
It uses a multi-agent AI/LLM pipeline to produce 15-20 minute radio segments on any number of niche topics. I love learning about diverse subjects, and this is what I built to foster that curiosity on the go.
You can listen to segments organized by "station", listen in randomized Radio Mode, and submit new topic requests to build out the content library. Each segment comes with sources, key details, and historical context for you to go even deeper.
It's still in the MVP stage - though I gussied it up a bit for you. No accounts, no personalization, and I trigger the segment production pipeline manually. Submit station ideas in the sidebar, and check back after a bit to listen!
My goal is to get feedback on whether this is an interesting idea - is it something you enjoy? Would you use it? It's provided me real value already. I also selfishly want more diversity in topics. That's where you come in :-)
