Show HN: Moonfish – AI podcast generator with research, writing, and voicing I built Moonfish because I have a long commute and kept wanting podcasts on niche topics that don't exist. It's like a combination of OpenAI's deep research and Google's NotebookLM – it searches the web for sources, synthesizes the information, and creates a conversational podcast with two AI hosts. It's very steerable. You create a show first, then add episodes to it. Set the tone at the show level ("explain like I'm a beginner or create podcast in xxx language"), then prompt individual episodes. Episode creation would take around ~3-5m and episode length is about 15 minutes right now (I'm working on extending that hopefully to an hour :) ) Underneath it comprises of three main agents - one agent searches and gathers sources, another structures the narrative, a third writes natural dialogue. The architecture is simple but very effective and scalable with new model release iOS app: https://ift.tt/6KWD1ky Would love to hear your feedbacks! https://ift.tt/6KWD1ky October 19, 2025 at 11:06PM
