Show Notes Generators Tested: Which AI Tools Actually Save You Time?

Running Castmagic, Podium, Swell AI (and a few others) head-to-head so you don’t waste hours doing what used to take minutes.

If you’re still laboring through writing show notes after hitting “Export,” you’re about to feel both relieved and vulnerable. The podcasting industry is rapidly shifting: more shows, more noise, and the difference between discovery and obscurity is often your metadata, not just the audio. Efficiency tools like AI-driven note-generators are no longer fringe toys, they’re becoming baseline workflow elements for networks, studios and indie creators alike. Lucky for you, I gave three of them the full stress-test so you can figure out which one actually moves the needle for your workflow.

Let’s set the stage. According to industry commentary, there are now over 4 million podcasts in existence, which puts enormous pressure on discoverability and efficiency. If you’re running a network with dozens of shows (or even just an indie running one show with aggressive growth goals - and you go!) every minute you save in post-production compounds.
