Overview
NotebookLM started as a Google research experiment and quickly became the go-to tool for turning documents into surprisingly engaging audio conversations. Its Audio Overview feature generates a two-host podcast-style discussion from whatever you upload, whether that's a PDF, a Google Doc, or a YouTube link. The voices sound natural and the banter feels organic, which caught a lot of people off guard when it first launched.
Jellypod takes a different approach. Rather than being a research tool with a podcast feature bolted on, it's built from the ground up for podcast production. You get custom AI hosts with distinct personalities, voice cloning, multi-episode series management, and distribution to Spotify, Apple Podcasts, and YouTube. The question isn't which tool sounds better in a demo; it's which one can actually power an ongoing podcast.
