Twitter Spaces Transcription

Twitter / X Spaces recordings are only kept for 30 days. After that, the conversation is gone unless someone downloaded it. If you host Spaces — for product launches, AMAs, founder chats, community discussions — that's a major gap. Hours of high-signal conversation, lost.

Castmagic accepts any X Space URL while the recording is still live, pulls the audio in under a minute, and returns a full transcript with speaker labels. From there, our AI turns the Space into a thread-ready recap, a blog post, a clip set, a pull-quote sheet, or a podcast-style show-notes document. Treat every Space like a podcast episode — because that's exactly what it is.

Twitter Spaces are podcasts that disappear in 30 days

Every X Space is a live audio conversation — single host, multiple co-hosts, an audience of listeners — that's recorded and replayable inside X for 30 days. After that retention window, the recording is gone. There's no native export, no archive, no transcript.

For hosts who run Spaces regularly — founders sharing product updates, journalists running AMAs, community builders hosting weekly discussions — that's hours of high-signal conversation lost every month. Castmagic solves it: paste the Space URL, get the audio file plus a transcript, repurpose into anything.

What you can do with a transcribed Space

The most common use case: a recap thread. The AI takes the transcript, identifies the most important moments, and drafts a tweet-sized thread you can post immediately after the Space ends — capturing the listeners who joined late and the ones who couldn't make it live. Engagement on these recap threads consistently beats engagement on the original Space link.

Beyond the recap thread: full blog post recaps for your newsletter, pull-quote graphics for LinkedIn or X, audio clips of the strongest moments for social, complete show-notes documents with chapter timestamps, and a podcast-ready edit if you want to syndicate the Space as a podcast episode.

Spaces are inherently a podcast format

Twitter / X Spaces share every structural element of a podcast episode: a host, guest speakers, an audience, long-form audio conversation, and content worth keeping. The only difference is the platform. Castmagic treats Spaces exactly like podcast episodes — same transcript quality, same AI presets, same content-generation library — so you can ship Spaces as podcast content if you want.

What about Spaces that have already expired?

If the Space recording is past X's 30-day retention window, the audio no longer exists on X's servers — there's nothing for any tool to download. The lesson most hosts learn after losing their first few Spaces: import every Space into Castmagic the same day you record it. The transcript and audio file are then yours forever.

For Spaces you've already hosted, check the Spaces section of your X profile and grab any recordings still in the retention window before they expire.
