YouTube Podcast Transcription

Copy the YouTube episode URL and paste it into Castmagic. We pull the audio and return a full transcript with speaker labels, timestamps, and AI-generated show notes — all in a few minutes.

YouTube's auto-captions are roughly 85-90% accurate on clean conversational audio and worse on technical, accented, or multi-speaker content. Castmagic consistently produces 95%+ accuracy with proper speaker attribution, paragraph breaks, and intelligent timestamps — and turns the transcript into publish-ready show notes, blog posts, and social clips automatically.

Yes. Castmagic uses speaker-diarisation to label each speaker in the transcript — host, co-host, guests. Speaker IDs are inferred from voice signatures; you can rename them in the Castmagic editor after transcription.

Yes. Castmagic generates chapter timestamps in YouTube's exact required format (e.g., 0:00, 4:23, 12:45) so you can paste them directly into a video description and YouTube will render them as a clickable chapter list.

Yes — Castmagic generates show notes in formats that match how major podcast hosts expect them (Spotify for Podcasters, Apple Podcasts Connect, Spreaker, Libsyn, Megaphone, Simplecast, and others). The output is plain-text or markdown, ready to paste.

No — Castmagic can only transcribe publicly-accessible YouTube videos. Members-only and YouTube Premium videos require account-level access that we don't have.

Castmagic offers a free tier so you can transcribe a YouTube episode and try the full workflow. Volume use — multiple episodes per week, longer videos, and AI-generated content output — is on paid plans.

An hour-long episode typically processes in 3-5 minutes. Multi-hour episodes (a long Joe-Rogan-style format) complete in 8-12 minutes. You'll get an in-app notification when it's ready.
