YouTube Transcript Summarizer Bot using n8n

📽️ YouTube Transcript Summarizer Bot 🤖

🚀 Overview

An AI-powered automation workflow that extracts transcripts from YouTube videos shared via Telegram and returns:

  • The full transcript as a .txt file.
  • A summarized version of the transcript using Google Gemini LLM.

This bot is built with n8n, combining various APIs and automation tools for a smooth and scalable experience.

⚙️ How It Works

  1. Telegram Trigger: The bot listens for YouTube links sent via Telegram.
  2. Validation: Verifies the video link and extracts the YouTube video ID.
  3. Transcript Extraction: Uses RapidAPI to fetch the transcript from the video.
  4. Text File Creation: Saves the transcript as a .txt file and sends it back to the user.
  5. Transcript Chunking: Breaks down the transcript into manageable parts.
  6. LLM Summarization: Sends chunks to Google Gemini for summarization.
  7. Final Output: Combines the results and sends a final summarized transcript to the user.
