Convert YouTube videos to audio summaries with Decodo, OpenAI & Telegram

Stop watching long videos, start listening to concise summaries.

This workflow transforms any YouTube video URL sent via Telegram into a high-quality, spoken audio summary (MP3) and a structured text overview. It acts as your personal AI research assistant, turning lengthy content into bite-sized audio files that you can consume on the go.

It leverages Decodo for robust transcript extraction, OpenAI for intelligent summarization, and for realistic text-to-speech generation.

✨ Features Telegram-First Interface: Send links and receive audio directly in your chat app. Smart Validation: Automatically checks if the link is a valid YouTube URL before processing to save API credits. Multi-Language Support: Easily configure the output language (English, Spanish, German, etc.) via a simple Config node. The AI will translate and speak in this language. Robust Error Handling: Gracefully handles videos with no captions/transcripts by notifying the user instead of breaking the workflow. Structured Data Extraction: Uses AI to extract the Genre, Title, and Summary alongside the audio file.

⚙️ How it Works 1. Trigger: You send a YouTube URL to your Telegram Bot. 2. Validate: The workflow checks the URL pattern using Regex. 3. Extract: Decodo scrapes the video page to retrieve the full transcript JSON. 4. Process: A Code node flattens the complex JSON into a readable text format. 5. Summarize: OpenAI (gpt-4o-mini) analyzes the text and writes a script optimized for listening. 6. Speak: OpenAI converts the script into a high-definition MP3 file. 7. Deliver: The bot replies with the Audio File and a formatted text summary including the genre tags and original link.
