Twitter Spaces Transcription

Copy the Space URL (twitter.com/i/spaces/<id> or x.com/i/spaces/<id>) while the recording is still within X's 30-day retention window, and paste it into Castmagic. We pull the audio and return an MP3 file you can keep permanently, alongside a full transcript.

X retains Space recordings for 30 days by default. After that, the recording is deleted and can't be recovered. To preserve a Space, save it through Castmagic while it's still within the retention window.

Yes — Castmagic works with any publicly-accessible X Space recording. You don't need X Premium, an X Spaces host account, or any special access. As long as the Space is public and within X's retention window, we can transcribe it.

Yes. Castmagic uses speaker-diarisation to attribute lines in the transcript to each participant — host, co-hosts, and audience members who spoke. Speaker labels are inferred from voice signatures; you can rename them in the Castmagic editor after transcription.

Yes. Many hosts use Castmagic to convert their X Spaces into proper podcast episodes — with show notes, chapter timestamps, edited audio, and a ready-to-publish RSS-feed-compatible MP3. Spaces are already a podcast format; Castmagic just gives them the polish.

Yes — this is one of the most-requested workflows. Castmagic's AI takes the Space transcript and drafts a thread-ready summary, broken into tweet-sized chunks, ready to post on X right after the Space ends. Most hosts use it to capture listeners who joined late or couldn't make it live.

As long as the Space was recorded by the host (and is publicly viewable), any participant can paste the URL into Castmagic and transcribe it. You don't have to be the host.
