YouTube to Telegram Summary Bot with Decodo & Gemini AI

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

Quick Installation Import: Load the JSON file into your n8n instance. Credentials: Add your API keys for Telegram, Decodo, and Google Gemini in the n8n credentials section. 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. 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").
