👤 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

🛠️ Requirements

🚨 API keys must be added manually — they are not included in the template.

🧩 How to Set It Up

  1. Configure the Telegram Trigger node with your bot token.
  2. In the HTTP Request node, set:
    • X-RapidAPI-Key: your RapidAPI key
    • X-RapidAPI-Host: your RapidAPI host URL
  3. Add your OpenAI API credentials to the AI Agent node.

Use the provided sticky notes for guidance inside the workflow itself.

🎛️ How to Customize

  • Modify AI prompt behavior in the AI Agent node
  • Change the text formatting in the Code node
  • Use a different transcript API if preferred
  • Add commands like make it into a blog post, summarize in bullet points, etc.

📌 Notes

  • All nodes are renamed to reflect their function
  • API credentials are removed for security
  • Includes colored boxes and sticky notes to guide the user
  • Compatible with n8n cloud and self-hosted setups
