💡 How It Works
This workflow automatically detects new YouTube uploads, retrieves their transcripts, summarizes them in Japanese using GPT-4 o mini, and posts the results to a selected Slack channel.
It’s ideal for teams who follow multiple creators, internal training playlists, or corporate webinars and want concise Japanese summaries in Slack without manual work.
Here’s the flow at a glance:
- YouTube RSS Trigger — monitors a specific channel’s RSS feed.
- HTTP Request via RapidAPI — fetches the video transcript (supports both English & Japanese).
- Code Node — merges segmented transcript text into one clean string.
- OpenAI (GPT-4o-mini) — generates a natural-sounding, 3-line Japanese summary.
- Slack Message — posts the title, link, and generated summary to #youtube-summary.
⚙️ Requirements
- n8n (v1.60 or later)
- RapidAPI account + [youtube-transcript3 API key]
- OpenAI API key (GPT-4o-mini recommended)
- Slack workspace with OAuth connection
