Chapters make your episodes navigable

Podcasting 2.0 chapters let listeners jump to any section of your episode directly in their podcast app. Apps like Overcast, Pocket Casts, Podverse, and Fountain all support them.

Chapters are defined in a simple JSON file hosted on your server, then referenced in your RSS feed with a single <podcast:chapters> tag. The Podcast Idiot RSS Feed Builder can add this tag for you automatically.

Podcasting 2.0 ready: This tool outputs the official JSON Chapters 1.2.0 format — upload it to your server and point to it from your RSS feed. Works with all Podcasting 2.0 apps.

Three steps to a chapter file

The AI reads your transcript timestamps, identifies the major topic shifts, and returns a properly-formatted JSON chapter file — ready to upload and reference in your feed.

  1. Upload a .vtt, .txt, or .json transcript from any transcription tool
  2. Enter your API key (or copy the free prompt for Claude.ai / ChatGPT)
  3. Review and edit the generated chapters, then download the JSON
