Yes, you can add chapters to your podcast. When publishing an episode in Fountain, you have two options.
Fountain starts generating chapters for your episode as soon as you upload your audio or video. You can also adjust the start time, title, link, and artwork for each chapter.
After you publish the episode, the chapters are included in your feed and available to listeners in apps that support chapters.
If you already have chapters from a third-party service, you can upload a JSON file instead. Check the box next to I want to upload my own chapters and choose the file.
You can also edit your chapters after uploading the file.
