💡 Pro Tip — YouTube’s API quotas can be a bottleneck when you’re pulling data at scale. ScraperNode is a community node with dedicated scrapers for channels, videos, and comments — no quota limits, just structured data.
Description
👤 Who’s it for
This workflow is for content creators, marketers, educators, or anyone who wants to instantly summarize YouTube videos and repurpose them into different formats (LinkedIn post, tweet, etc.) via a simple Telegram chatbot.
⚙️ How it works
This n8n automation listens for messages in Telegram. If the message contains a YouTube link, it:
- Extracts the video ID
- Fetches the video transcript using RapidAPI
- Cleans the transcript of any special characters
- Sends it to OpenAI to generate a summary
If the message is not a link, it simply acts as an AI chatbot using OpenAI with memory support.
✅ Supports follow-up prompts like:
- “Make it shorter”
- “Turn this into a LinkedIn post”
- “Create a tweet thread”
🧑🤝🧑 Multi-User Support
This Telegram bot supports multiple users simultaneously. It tracks memory and context separately for each user using Telegram’s unique chat_id.
✅ Each user gets personalized AI replies
✅ Follow-up commands work per user
✅ No interference between users
