WhipScribe turns a castro.fm episode link shared from Castro into a timestamped transcript. Packs: $4 for 500 minutes, $12 for 2,000, $24 for 5,000; Workspace $19 a month. Up to 10 hours or 5 GB per file. Measured turnaround: about 2 minutes per audio hour. 99 languages. Checked 25 Oct 2026.
How it works
Castro's share link opens a public episode page that points at the episode's audio.
In Castro, open the episode, tap share and copy the link. It looks like castro.fm/episode/ followed by a short code.
Whipscribe follows the link to the episode's audio. The transcript preview opens without an account.
Speakers are named in the summary, key quotes and chapters, and every word carries a timestamp. Export TXT, DOCX, SRT, VTT or JSON.
| Link you paste | What gets transcribed |
|---|---|
castro.fm/episode/AbCdE | That episode |
A direct .mp3 link to the episode | That file |
| The show's RSS feed link | The newest episode |
If a link is refused, you see a message straight away and nothing is queued. Paste the episode's MP3 link or the show's RSS feed instead, or download the episode and drop the file in the box. The box takes files up to 500 MB; larger files continue on the upload page. Episodes from private feeds you added to Castro cannot be read from a link; if the show lets you download the file, upload it instead.
What listeners and podcasters do with it
Castro helps you decide what to listen to. A transcript helps you keep what you heard.
Queue backed up? Read the transcript of a news or interview episode and listen only to the part you care about.
Copy the passages that matter into your notes, each with a timestamp, so going back to the audio takes one click.
Every line carries its timestamp in the transcript view on this page.
Podcasters can paste their own public episode link and get a DOCX to shape into show notes, and SRT or VTT captions for video clips.
Castro's own transcripts
Castro displays transcripts that podcasters include in their show's feed. Not every show does, and Castro's own blog noted that only a minority of new episodes carried one when it added support.
When an episode has no transcript, or you want a file rather than text inside the app, paste the Castro link here. You get word-level timestamps and five export formats, kept in a library you can search.
Most shows you find on Castro belong to someone else. Transcribing a public episode for notes, study or research is common; before publishing the transcript or long quotes, ask the podcaster and credit the show. This is not legal advice.

What it costs
A 25-minute show that publishes every weekday comes to about 20 episodes and 500 minutes a month. The $12 pack of 2,000 minutes covers four months of it, about $3 a month or 15 cents an episode.
Packs from $4, credits never expire. Full details on the pricing page.
FAQ
Castro shows a transcript when the podcaster includes one in the show's feed. Many episodes have none. Whipscribe makes a transcript from the episode's audio either way, and exports.
Tap share on the episode in Castro, copy the castro.fm/episode/ link and paste it into the box on this page. A preview appears straight away with no signup; a pack from $4 opens the full transcript.
You see a message straight away and nothing is queued. Paste the episode's MP3 link or the show's RSS feed instead, or download the episode and upload the file.
Not from a link, because private feed episodes have no public page. If you can download the file, drop it in the upload box.
Yes for your own reading, notes and research, which is how most listeners use it. Before you publish a transcript or long quotes, ask the podcaster and credit the show. This is not legal advice.
Your transcripts are kept in your account's searchable library, and your audio and transcripts are never used to train AI models. A link only reaches episodes that are already public.
Instant preview, no signup, no card. A free account keeps your transcripts in one library.
