Stop wasting hours watching long videos. This n8n workflow acts as your personal "TL;DW" (Too Long; Didn't Watch) assistant. It automatically pulls YouTube transcripts using Decodo, analyzes them with Google Gemini, and sends a detailed summary straight to your Telegram.

Why You Need This

  • Save Time: Turn a 2-hour video into a 5-minute read (95% faster).
  • Don't Miss a Thing: Captures key points, chapters, tools mentioned, and quotes that you might miss while skimming.
  • Instant Results: Get a structured summary in Telegram within 30-60 seconds.
  • Multi-Language: Works with any video language that has YouTube captions.

Who Is This For?

  • Creators & Marketers: Spy on competitor strategies and extract tools without watching endless footage.
  • Students: Turn lecture recordings into instant study notes.
  • Busy Pros: Digest conference talks and webinars on the go.

How It Works

  1. Send Link: You message a YouTube link to your Telegram bot.
  2. Scrape: The bot uses the Decodo API to grab the video transcript and metadata (views, chapters, etc.).
  3. Analyze: Google Gemini reads the text and writes a structured summary (overview, takeaways, tools).
  4. Deliver: You receive the formatted summary in chat.

Setup Guide

What You Need

Quick Installation

  1. Import: Load the JSON file into your n8n instance.
  2. Credentials: Add your API keys for Telegram, Decodo, and Google Gemini in the n8n credentials section.
  3. Configure:
    • In the "Alert Admin" node, set the chatId to your Telegram User ID (find it via @userinfobot).
    • (Optional) Change the languageCode in the Config node if you want non-English transcripts.
  4. Test: Send a YouTube link to your bot. You should see a "Processing..." message followed by your summary!

Troubleshooting & Tips

  • "Not a YouTube URL": Make sure you are sending a standard youtube.com or youtu.be link.
  • No Transcript: The video must have captions (auto-generated or manual) for this to work.
  • Customization: You can edit the AI Prompt in the "Generate TLDR" node to change how the summary looks (e.g., "Make it funny" or "Focus on technical details").
