What is YouTube Summarizer?
The YouTube Summarizer is a sophisticated tool designed for Openclaw Skills to help developers and researchers digest video content rapidly. It doesn't just watch a video; it cross-references the title and channel with web search results to provide a high-context summary that includes market impact, competitive analysis, and key quotes. This ensures users get a 360-degree view of the topic without spending hours watching the original footage.
This skill is particularly powerful for processing technical keynotes, product launches, and educational lectures. By combining internal transcript data with external tech journalism, it delivers a level of depth that standard summarizers cannot match, making it an essential part of any developer workflow using Openclaw Skills.
YouTube Summarizer Use Cases
- Summarizing tech product launches and enterprise keynotes for quick decision-making.
- Extracting key insights and technical requirements from long-form engineering lectures.
- Analyzing market reactions to official company announcements and news reports.
- Generating bilingual reports in English or Chinese based on user preference.
How YouTube Summarizer Works
- The skill extracts the unique 11-character video ID from any standard YouTube URL format provided by the user.
- It fetches basic metadata such as the video title, channel name, and description using a web fetcher.
- A targeted search is performed to find high-quality external sources (like TechCrunch or official blogs) to provide context beyond the video itself.
- The agent retrieves the video transcript or detailed reporting with a high character limit to ensure no critical information is lost.
- All gathered data is synthesized into a structured Markdown template, specifically chosen based on whether the content is an event or a lecture.
YouTube Summarizer Setup
This skill is part of the Openclaw Skills ecosystem and is typically located in your workspace directory. To use the auxiliary script for manual extraction, follow these steps:
# Navigate to the skill directory
cd ~/.openclaw/workspace/skills/youtube-summarizer/
# Basic usage to fetch video information
node scripts/youtube-info.js "https://www.youtube.com/watch?v=VIDEO_ID"
# Fetch full transcript with timestamps
node scripts/youtube-info.js VIDEO_ID --transcript-full
# Output as JSON for programmatic parsing
node scripts/youtube-info.js VIDEO_ID --json
