Source: Podcast Index feed dump, 16 August 2026, all 4,711,475 rows.

A feed belongs to a platform when:

- Jellypod: the generator tag contains "Jellypod" or the host is jellypod.ai or jellypod.com.
- PodcastAI: the generator tag is "PodcastAI" or the host is podcastai.com.
- Wondercraft: the host is wondercraft.ai.
- Play.ht: the generator tag is "Play.ht" or the host is play.ht.
- PoddyHost AI: the generator tag is "PoddyHost.com AI Podcast Platform".
- AutoContent API: the generator tag names AutoContent API or the host is autocontentapi.com.

Feeds that use AI voices but publish through a general host (Buzzsprout, Spotify for Creators, Spreaker and others) carry no such marker and are not counted.

No episode: episodeCount is 0, or the feed lists no dated episode. 1,533 Jellypod feeds have a title ending in "(feed disabled)" and list no episodes.

Published in the last 90 days: newestItemPubdate on or after 18 May 2026.

Baseline: all 661,852 feeds Podcast Index added from 1 January 2025 to 16 August 2026 (createdOn). 212,376 of them (32.1%) published in the last 90 days. For the one-or-fewer-episodes share, Buzzsprout feeds are left out because their episodeCount is unreliable in the dump: 174,927 of 593,055 (29.5%).
