Repurpose Riverside Recordings

Export the recording and drag it into Castmagic — it transcribes in minutes. Then choose the content preset (or your own prompt) and Castmagic drafts it from the recording, in your voice. Edit it, drop in your links, and publish. The whole loop takes a few minutes instead of an afternoon.

Yes — that's the point. Castmagic drafts from your actual words, and you can give it a custom prompt with your tone, structure, and rules (no hashtags, short sentences, your sign-off). Save it as a recurring prompt and every episode comes out on-brand. You stay the editor; it removes the blank page.

For a single recording, the Castmagic app is the fastest path. When you want to work across your entire library at once — a lead magnet from your best episodes, a book, a course — connect Castmagic to Claude with the MCP connector and Claude can search and build from every recording you have. See castmagic.io/claude.

Castmagic uses state-of-the-art speech models with 60+ languages, automatic language detection, and speaker labeling. Clear audio typically transcribes well above 95% accuracy, and a custom-vocabulary list keeps names, products, and jargon spelled right — so the content is built on a clean source.

Castmagic has a free tier so you can run a StreamYard recording through the full workflow and see the output. Higher volume — more recordings per week, longer files, and unlimited content generation — is on the paid plans.

Export the recording from Riverside — audio or video — then drag the file into the uploader above. There’s no link to paste: Riverside recordings are private exports, so Castmagic works from the file itself and transcribes the spoken track either way.

Yes. Castmagic applies speaker labels so each host and guest is separated in the transcript, which keeps quotes and takeaways attributed correctly in the draft.

Multi-hour Riverside sessions are fine. A typical hour transcribes in minutes, and longer interviews and panels work the same way.
