cast0

Turn text into podcast episodes. One AI voice narrates your finished text (text-to-speech) in 70+ languages, and cast0 hosts the audio. Listen right in the chat with the built-in player, or subscribe to your RSS feed in Apple Podcasts, Overcast, or Pocket Casts, where every new episode appears automatically. Works for briefings, articles, newsletters, and research summaries. Episodes can open with a short teaser, and you can add intro and outro music in the cast0 dashboard. No API key or setup needed: sign in to cast0 when you connect, and your first episode creates the podcast. cast0 reads text as supplied. It does not summarize, translate, fetch content, schedule, clone voices, or create multi-host conversations. cast0 does not list your feed publicly; anyone with its link can open it.

Use cast0 to make a finished briefing, report, article, or newsletter an episode you can listen to on a walk or commute. It handles text-to-speech, audio hosting, and RSS publishing together. You do not have to subscribe to anything: each episode plays in the inline player once it is ready. In clients without the player, you get an audio link instead. If you subscribe, new episodes appear in the same feed after generation finishes.

Create an episode, check its generation status, play completed audio, list your episodes, and get your podcast's RSS subscribe link. You can also rename your podcast or choose from its available stock voices. Generation runs in the background; the inline player checks progress and becomes playable when ready.

Narration supports 70+ languages with the default voice model. Write the text in the language you want to hear. An episode can start with a short teaser that is read before the main text. Intro and outro music and the voice model are set in the cast0 dashboard, along with speaking speed for voice models that support it. Music plays around the episode and briefly overlaps its first and last words.

Sign in or create a cast0 account during connection. You do not need an API key or a separate dashboard setup to make your first episode. Episodes have a length limit and count toward your account's usage limits.

Provide the text you want narrated. cast0 does not fetch articles, read email inboxes, schedule recurring briefings, rewrite, summarize, or translate text, transcribe recordings, clone voices, or generate conversations between multiple hosts. ChatGPT can help prepare your text before you ask cast0 to publish it. Share feed and audio links only with people you want to have access; they do not require a listener login.
