AI Agent - YouTube Description Writer incl. Timestamps/Chapters

Stop writing YouTube descriptions. This n8n AI agent system does it for you.

Send any YouTube link (even Shorts!) via Telegram and instantly get:

• 5 SEO-Friendly Title ideas
• A Full, Formatted Video Description
• Automatic Video Chapters and Timestamps

Powered by a multi-agent AI flow, this workflow scrapes the transcript of your video, writes all your description content content, and creates the timestamps and chapter text for your video description.

This is a sophisticated dual-agent AI system built for YouTube creators.

How this workflow works

This workflow uses a "Chain of Thought" process with two distinct AI agents:

1. The Transcript Agent: First, it uses an Apify actor to scrape the video's entire transcript. It analyzes this raw data to generate a detailed summary and calculate the exact start times for each new topic, creating perfect chapters.
   
   Note: Put your Apify Credentials on the Apify Node

   

   
   
2. The Formatting Agent: This agent takes the structured data, brainstorms 5 click-worthy titles, and formats the description, chapters, and your personal footer into clean HTML, ready to be copied and pasted directly into YouTube.

Features

• 🤖 Advanced Dual-Agent System: A robust LangChain-style architecture that intelligently processes and formats content.
• 📈 Production-Ready Logging: Automatically logs every request, the AI's output, and (most importantly) the exact LLM token cost to a Google Sheet.
• ⚙️ Robust Error Handling: Never fails silently. If an error occurs (like a bad link), it notifies you in Telegram and logs the failure in your Google Sheet.
• 🔗 Smart URL Conversion: Automatically detects and converts "YouTube Shorts" links into standard video links that the scraper can read.
• 💬 Conversational Memory: The bot remembers your conversation history for each unique user, allowing for natural follow-up interactions.
