X Spaces (formerly Twitter Spaces) have become one of the fastest-growing social audio formats since 2023: more than 4 million Spaces are created each month, with audiences regularly exceeding 10,000 simultaneous listeners in sessions hosted by founders, marketers, journalists and crypto communities. But every host shares the same frustration: the Space content dies a few hours after the session ends.
X offers live captions but does not save them. The recording remains available as audio only, with no text, no summary and no search. If you want to convert a Space into a thread, a newsletter or a blog post, you have to listen to the entire audio and take notes. In this guide you will see how to transcribe any X Space (even if you are not the host) and obtain a complete analysis with summary, tasks and decisions in less than five minutes.

Why transcribe your X Spaces
A Space can last anywhere between 30 minutes and several hours. That much content represents a goldmine of insights, quotes, announcements and debates, but only if you can access it in text form. The five most common reasons to transcribe a Space are:
- Content repurposing: A 60-minute Space yields a 25-tweet X thread, a long LinkedIn post, two newsletter sections and an SEO blog article. Without a transcript, that work is manual and exhausting.
- SEO: Google does not index audio. If you want your Space to drive organic traffic months later, you need the text on a public page (your blog, your Substack or your Notion site).
- Accessibility: Listeners with hearing impairments cannot follow a live Space or its recording. A transcript meets the basic WCAG 2.1 accessibility requirements.
- Internal search: If your community or team runs weekly Spaces, you quickly accumulate an unmanageable archive. Without text, finding "what Marta said about the Q3 roadmap" is impossible.
- Viral clips: The best quotes from a Space become video shorts, square posts and quote tweets. To extract them you need text and timestamps.
What X offers (and what it doesn't) in 2026
X has invested in improving the Spaces experience, but the transcription and analysis layer remains nearly nonexistent. Here is what is available today.
What X DOES offer
- Live captions: During the Space, listeners can enable auto-generated captions in real time. They work reasonably well in English, less reliably in other languages.
- Audio recording: If the host activates "Record Space" when creating the session, the recording remains available to replay from the public link for 30 days.
- Download for the host: The host can download the MP4 audio from the creator panel in X Pro / Studio, within 30 days after the event.
What X does NOT offer
- Saved transcript: Live captions are not stored. When the Space ends, the text disappears forever.
- Automatic summary: There is no AI feature that extracts the summary, key points or decisions from the Space.
- Action items or tasks: If commitments are made during the Space ("Marta sends the proposal on Friday"), nobody captures them automatically.
- Download for non-hosts: If you are not the host, X offers no download button, even when the Space is public and recorded.
- Search inside the content: You cannot search words inside the Space audio.
Heads up: Space recordings are deleted automatically after 30 days if the host does not download them. If you want to archive your historical Spaces for future repurposing, download them as soon as possible and process them with VOCAP. After 30 days, recovering them is practically impossible.
Transcribe a Space with VOCAP (step by step)
The full flow from a recorded Space to a structured transcript + summary + tasks takes less than five minutes.
Locate the recorded Space
Open the Space link on X. Verify that the Recorded tag appears next to the title. If not, the host did not enable recording and you cannot recover it. If you are the host, go to your creator Studio on x.com.
Download the Space audio
If you are the host, download the MP4 from Studio > Audio Spaces > Download (section 4 below). If you are not the host, use a tool like twspace_dl or record the playback with QuickTime (macOS) or OBS Studio (Windows/Linux).
Upload the file to VOCAP
Go to vocap.io/en/transcribe, log in (or create a free account with 30 minutes included, no card required). Drag the MP3 or MP4 to the upload area. VOCAP accepts up to 150 MB. For Spaces over 2 hours, compress the file to 64 kbps mono before uploading.
Wait for transcription (3-8 minutes)
VOCAP processes the audio with OpenAI's Whisper model, splitting it into parallel chunks to reduce wait time. A 60-minute Space is transcribed in about 4 minutes. You receive the full text with speaker breaks.
Receive AI analysis with Claude
After transcription, VOCAP sends the text to Claude (Anthropic) which automatically extracts: executive summary, key points, highlighted quotes, decisions, tasks mentioned and overall tone of the Space. Everything structured in copy-ready sections.
Turn the Space into new content
Use the summary as a base for your X thread, the quote list to create clips, the key points for your newsletter and the full transcript for an SEO blog post. A single Space can give you content for 2 weeks.

Try VOCAP FreeHow to download the audio of an X Space
This is the part that causes the most confusion. Summary by scenario:
Scenario 1: You are the host of the Space
- Go to x.com and log in with the account that created the Space
- Open your profile and navigate to Spaces from the sidebar (also accessible from Studio for verified Premium accounts)
- Locate the Space in the "Recorded" list
- Click the options menu and select Download recording
- You get an MP4 file (audio + cover) with the entire Space
Scenario 2: You are not the host but the Space is recorded
You have three options, ranked from most to least convenient:
- Open source tool twspace_dl: Direct download of the original M4A from the Space URL. Requires Python and ffmpeg. Best quality option.
- Record system playback: On macOS open QuickTime > File > New Audio Recording and select "BlackHole" or "Loopback" as source. Play the Space and record simultaneously. Then extract the audio.
- Web services like "Twitter Space downloader": Paste the URL and download the MP3. They work sometimes, but heavily depend on changes in the X API. Not recommended for sensitive content due to privacy concerns.
Scenario 3: The Space ended more than 30 days ago
X automatically deletes recordings after 30 days unless the host downloads them. If more than 30 days have passed, the audio likely no longer exists on X servers. Reach out to the host directly to ask if they kept the original MP4.
Pro tip: If you host Spaces regularly, automate the download immediately after every session and process the audio with VOCAP in the same workflow. You will have transcript + summary available within an hour and can schedule repurposing on X, LinkedIn and newsletter for the same afternoon, while your audience still remembers the event.
Native solution vs VOCAP: 2026 comparison
| Feature | X (native) | VOCAP | Otter / Descript |
|---|---|---|---|
| Saved Space transcript | No | Yes (95%+ EN) | Yes |
| Executive summary | No | Yes (Claude Sonnet 4) | Pro plan only |
| Tasks & decisions extracted | No | Yes, with owners | Basic action items |
| Works if you are not the host | No | Yes (you download the audio) | Yes |
| Multilingual accuracy | EN-focused | 95%+ in EN/ES/FR/DE/IT/PT | EN-focused |
| Pricing model | Free (no transcript) | Pay-per-use ($1.99/h) | $17/month minimum |
| GDPR / EU data | US servers | GDPR compliant | US servers |
When VOCAP wins: creators who host occasional Spaces and don't want a monthly subscription, multilingual teams where accuracy is critical, hosts who need a structured summary for repurposing, and companies with GDPR requirements. When Otter or Descript wins: US teams in English with existing monthly subscriptions and very high transcription volume each month.

The quality of the analysis depends directly on the quality of the Space audio. These are the tweaks with the biggest impact.
As a Space host
- Ask speakers to use earbuds with mic: Avoids echo and dramatically improves transcription accuracy
- Moderate turns: When two people talk at once, Whisper struggles to differentiate. Hand off the floor explicitly
- Announce the name before each long intervention: "Marta, over to you" helps Claude attribute quotes correctly in the analysis
- Verbalize commitments: Say "action for Pedro: send the deck before Friday". Claude extracts it as a task with an owner
- Always enable recording: No recording, no later transcript. The toggle is in the Space creation modal
Before uploading to VOCAP
- Trim long intros and outros: If the first and last 5 minutes are music or silence, trim them with QuickTime to save minutes from your account
- Compress if larger than 150 MB: Convert to MP3 64 kbps mono with FFmpeg:
ffmpeg -i space.mp4 -vn -ac 1 -b:a 64k space.mp3 - For multi-hour Spaces: Split into thematic blocks (intro, panel 1, Q&A) and process each block separately for more useful analysis
Without AI transcription

Frequently asked questions
Does X (Twitter) transcribe Spaces automatically?
X offers live captions during the Space, but those captions are not saved or exported: they disappear when the session ends. The recording that remains available after the Space is audio only, with no transcript or summary. If you need the full text of a Space for repurposing, search or accessibility, you have to transcribe it separately. VOCAP converts any Space recording into text + summary + action items with 30 minutes of free transcription when you sign up.
Can I transcribe a Space if I am not the host?
Yes, as long as the Space was recorded by the host (the Recorded tag usually appears next to the title). Any listener can replay the recording from the public link. To transcribe it, capture the audio with a download tool like twspace_dl or record the playback with a screen capture tool and extract the audio. Then upload the MP3 to VOCAP. Remember to respect the author's rights before publishing the transcript publicly.
How do I download the audio of a recorded X Space?
If you are the host, X lets you download the MP4 from your Spaces panel (Studio > Audio Spaces > Download). If you are not the host but the Space is recorded, you can use open source tools like twspace_dl on GitHub, which downloads the original M4A from the URL. As a universal alternative, replay the Space and record system audio with QuickTime (macOS), OBS Studio or the Windows built-in recorder. Once you have the file, upload it to VOCAP.
Does Space transcription work well in non-English languages?
Yes. VOCAP uses OpenAI's Whisper model, trained on thousands of hours of audio across English, Spanish, French, German, Italian, Portuguese and dozens more languages. Accuracy is 95% or higher even with strong accents, code-switching (very common in tech Spaces) and specialized vocabulary from marketing, crypto or startups. For Spaces with multiple speakers, the Claude analysis approximately identifies who said what and summarizes interventions per participant.
Why transcribe a Space at all?
The main use cases are: (1) content repurposing (a 1-hour Space becomes an X thread, LinkedIn carousel, newsletter and blog post), (2) accessibility for people with hearing impairment, (3) SEO because text is indexable while audio is not, (4) internal search across history, (5) extracting quotes for video clips, and (6) creating recap notes for community or team members who could not attend live. A transcript multiplies the lifespan of every Space tenfold.
