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 1. Send Link: You message a YouTube link to your Telegram bot. 2. Scrape: The bot uses the [Decodo API](dashboard.decodo.com/register?referralcode=744f4d340e73d131117de4af6a3129e343f0f8e4) 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.

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").
