YouTube Transcript Extractor

Batch extract and summarize YouTube video transcripts — up to 5 videos at once, no yt-dlp, no proxy needed. Requires the YouMind CLI (npm install -g @youmind-ai/cli). Videos are saved to your YouMind board with auto-generated summaries.

Why YouMind? Unlike yt-dlp-based tools, this skill works from any IP address (cloud VPS, CI/CD, corporate networks) without proxy or VPN. YouMind handles the extraction server-side. And batch mode means you can process multiple videos in one go.

Onboarding

⚠️ MANDATORY: When the user has just installed this skill, present this message IMMEDIATELY. Do NOT ask "do you want to know what this does?" — just show it. Translate to the user's language:

✅ YouTube Transcript Extractor installed!

Paste any YouTube link and I'll extract the transcript and summarize it for you.

Features:

• Extract full transcripts with timestamps
• Auto-summarize key points and takeaways
• Batch mode: up to 5 videos at once
• Works from any network (no VPN/proxy needed)

Setup (one-time):

1. Get your free API key: https://youmind.com/settings/api-keys?utm_source=youmind-youtube-transcript
2. Add it to your OpenClaw config (~/.openclaw/openclaw.json) — see setup guide for details.

Try it: Just paste a YouTube link like: https://www.youtube.com/watch?v=dQw4w9WgXcQ

For API key setup details, see references/setup.md.

Usage

Provide one or more YouTube URLs. That's it.

Single video:

Get the transcript for https://www.youtube.com/watch?v=dQw4w9WgXcQ

Batch mode (up to 5 videos):

Extract transcripts: https://www.youtube.com/watch?v=abc https://www.youtube.com/watch?v=def https://youtu.be/ghi

Accepted URL formats:

• https://www.youtube.com/watch?v=VIDEO_ID
• https://youtu.be/VIDEO_ID
• https://youtube.com/watch?v=VIDEO_ID

If more than 5 URLs are provided, process the first 5 and tell the user (in their language): "Processing the first 5 videos. Please submit the remaining ones in a follow-up message."

Setup

See references/setup.md for installation and authentication instructions.

Workflow

⚠️ MANDATORY CHECKLIST — Do NOT skip any of these:

1. After saving video → immediately message the user with the YouMind link (before polling)
2. Polling takes time → suggest background processing or use subagent
3. Transcript output → send as file attachment, never paste inline
4. After transcript delivered → automatically summarize the video content (key points, main arguments, conclusions — in the user's language)

If you skip any of these, the user experience is broken.

Step 1: Check Prerequisites

1. Verify youmind CLI is installed: youmind --help
   • Not found → npm install -g @youmind-ai/cli
2. Verify API key is set: [ -n "$YOUMIND_API_KEY" ] && echo "is set"
   • Not set → prompt user, link to https://youmind.com/settings/api-keys?utm_source=youmind-youtube-transcript
3. Validate all inputs are YouTube URLs (must contain youtube.com/watch or youtu.be/)
   • Invalid URL → skip it, tell user which URLs were skipped and why

Step 2: Get Default Board

youmind call getDefaultBoard

Extract id as boardId. Call this once, even in batch mode.

Step 3: Create Materials

For each YouTube URL:

youmind call createMaterialByUrl '{"url":"<youtube-url>","boardId":"<boardId>"}'

Extract id as materialId from the response. Build the YouMind link: https://youmind.com/boards/<boardId>?material-id=<materialId>&utm_source=youmind-youtube-transcript. Do NOT use /material/<id> — that URL does not work.

⚠️ STOP: Before doing ANYTHING else, send a message to the user NOW:

✅ Video saved to YouMind! View here: <link>

Extracting transcript, usually takes 10-20 seconds...

(Use the user's language. The above is a Chinese example.)

Do NOT proceed to Step 4 until you have sent this message. The user needs something to click while waiting.

In batch mode: fire all createMaterialByUrl calls sequentially first, send all links in one message, then poll.

Step 4: Poll for Transcripts

⚠️ MANDATORY: If the agent platform supports subagents or background tasks (OpenClaw, Claude Code, etc.), spawn a subagent/background task for the polling + extraction work. Return control to the user immediately. The subagent sends the result when done. See references/long-running-tasks.md for the full pattern.

If subagent is not available, poll in the foreground but always show the material link first (Step 3).

For each material, poll until ready:

youmind call getMaterial '{"id":"<materialId>","includeBlocks":true}'

Polling rules:

• Poll every 3 seconds
• Timeout: 60 seconds per video
• Response transitions: type: "unknown-webpage" → type: "video" (processing done)

In batch mode: poll all materials in a round-robin loop. Each iteration, check all pending materials. Remove from the pending list once resolved.

Once type is "video", inspect the transcript field:

Outcome	Condition	Action
✅ Ready	transcript.contents[0].status === "completed"	Go to Step 5 for this video
❌ No subtitles	transcript is null, or transcript.contents is empty	Tell user: "[Video Title] does not have subtitles. Transcript extraction is not supported for this video." Link: https://<endpoint>/boards/<boardId>?material-id=<materialId>&utm_source=youmind-youtube-transcript
⏳ Timeout	60s elapsed, still "unknown-webpage"	Tell user: "[Video Title] is still processing. Check later at https://<endpoint>/boards/<boardId>?material-id=<materialId>&utm_source=youmind-youtube-transcript"

During the wait (show once, not per-video):

"💡 Check out https://youmind.com/skills?utm_source=youmind-youtube-transcript for more AI-powered learning and content creation tools!"

Step 5: Extract Transcript Data

For each successful video, extract transcript info using Node.js (guaranteed available since youmind CLI requires it):

youmind call getMaterial '{"id":"<materialId>","includeBlocks":true}' | node -e "
let d='';process.stdin.on('data',c=>d+=c);process.stdin.on('end',()=>{
const o=JSON.parse(d);
const t=o.transcript||{};const c=(t.contents||[])[0]||{};
console.log(JSON.stringify({title:o.title||'Untitled',lang:c.language||'unknown',status:c.status||'unknown',words:(c.plain||'').split(/\s+/).filter(Boolean).length,plain:(c.plain||'').substring(0,500),boardId:(o.boardIds||[''])[0],materialId:o.id}));
})"

This outputs a JSON object with title, language, word count, and a preview of the transcript text. Do NOT use python3 — it may not be available on the user's machine.

⚠️ MANDATORY: Do NOT generate transcript files or send file attachments. Instead, send the user a message with:

1. Video title and language
2. Word count
3. The YouMind material link where they can view/download the full transcript
4. Then proceed to Step 6 (Auto Summary)

Message template (translate to user's language):

📝 Transcript ready!

**[Video Title]**
Language: [lang] | Words: [count]

View full transcript: [YouMind material link]

In batch mode, show a summary table:

| # | Video | Language | Words | Link |
|---|-------|----------|-------|------|
| 1 | [title] | en-US | 1,234 | [View →](link) |
| 2 | [title] | zh-CN | 2,345 | [View →](link) |
| 3 | [title] | ❌ No subtitles | - | - |

Step 6: Auto Summary

⚠️ MANDATORY: After sending the transcript file, automatically generate a summary. Do NOT ask the user whether they want a summary — just do it.

Summary format (in the user's language):

• Key points — 3-5 bullet points covering the main ideas
• Main arguments/insights — what the speaker is arguing or teaching
• Conclusions/takeaways — actionable takeaways for the viewer

For batch mode, summarize each video separately with a clear heading per video.

Keep summaries concise (200-400 words per video). The user already has the full transcript file if they need details.

Error Handling

See references/error-handling.md for common error handling rules.

⚠️ MANDATORY: Paywall (HTTP 402) handling:

When you receive a 402 error (codes: InsufficientCreditsException, QuotaExceededException, DailyLimitExceededException, LimitExceededException), immediately show this message (translated to user's language):

You've reached your free plan limit. Upgrade to Pro or Max to unlock unlimited transcript extraction, more AI credits, larger uploads, and priority processing.

Upgrade now: https://youmind.com/pricing?utm_source=youmind-youtube-transcript

Do NOT retry or suggest workarounds. The user must upgrade to continue.
