This workflow automatically turns any YouTube video into a structured blog post with Gemini AI. By sending a simple POST request with a YouTube URL to a webhook, it downloads the video’s audio, transcribes the content, and generates a blog-ready article with a title, description, tags, and category. The final result, along with the full transcript and original video URL, is delivered to your chosen webhook or CMS.

How it works:

The workflow handles the entire process of transforming YouTube videos into complete blog posts using Gemini AI transcription and structured text generation. Once triggered, it:

  • Downloads the video’s audio
  • Transcribes the spoken content into text
  • Generates a blog post in the same language as the video’s original language
  • Creates:
    • A clear and engaging title
    • A short description
    • Suggested category and tags
    • The full transcript of the video
    • The original YouTube video URL

This makes it easy to repurpose video content into publish-ready articles in minutes.

This template is ideal for content creators, marketers, educators, and bloggers who want to quickly turn video content into written posts without manual transcription or editing.

Setup Instructions

  1. Install yt-dlp on your local machine or server where n8n runs. This is required to download YouTube audio.
  2. Get a Google Gemini API key and configure it in your AI nodes.
  3. Webhook Input Configuration:
    • Endpoint: The workflow starts with a Webhook Trigger.
    • Method: POST
    • Example Request Body:
{
	"videoUrl": "https://www.youtube.com/watch?v=lW5xEm7iSXk"
}
  1. Configure Output Webhook: Add your target endpoint in the last node where the blog post JSON is sent. This could be your CMS, a Notion database, or another integration.

Customization Guidance

  • Writing Style: Update the AI Agent’s prompt to adjust tone (e.g., casual, professional, SEO-optimized).
  • Metadata: Modify how categories and tags are generated to fit your website’s taxonomy.
  • Integration: Swap the final webhook with WordPress, Ghost, Notion, or Slack to fit your publishing workflow.
  • Transcript Handling: Save the full transcript separately if you also want searchable video archives.

Automated YouTube Video to Blog Post Conversion with Gemini AI Transcription

This n8n workflow automates the process of converting YouTube video content into structured blog posts using Google Gemini AI for transcription and content generation. It's designed to streamline content creation by transforming video dialogues into written articles.

What it does

This workflow performs the following key steps:

  1. Receives a Trigger: It starts by listening for an incoming webhook, which is expected to provide the necessary information to initiate the video processing.
  2. Executes a Command: It runs a shell command, likely to download the YouTube video or extract its audio for transcription.
  3. Reads/Writes Files from Disk: It interacts with the local file system, presumably to handle the downloaded video/audio file and any generated transcripts.
  4. Processes with Google Gemini AI: It utilizes the Google Gemini node, likely to transcribe the audio from the YouTube video.
  5. Generates Content with AI Agent: An AI Agent node (powered by LangChain) takes the transcription and other inputs to generate the blog post content. This step could involve summarizing, structuring, and enriching the transcribed text.
  6. Parses Structured Output: A Structured Output Parser node (from LangChain) is used to ensure the AI-generated content adheres to a predefined structure, such as JSON, making it ready for further use (e.g., publishing to a CMS).
  7. Edits Fields: A Set node is used to manipulate or add fields to the data, preparing it for the final response.
  8. Responds to Webhook: Finally, it sends a response back to the original webhook trigger, likely indicating the success or providing the generated blog post content.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Google Gemini API Key: Access to the Google Gemini API for transcription and AI capabilities.
  • LangChain Integration: Ensure the @n8n/n8n-nodes-langchain package is installed in your n8n instance.
  • Shell Access: The n8n instance needs to be able to execute shell commands (e.g., yt-dlp or youtube-dl for video download, or a similar tool for audio extraction).
  • Storage: Sufficient disk space on your n8n host to temporarily store video/audio files.

Setup/Usage

  1. Import the Workflow: Download the workflow JSON and import it into your n8n instance.
  2. Configure Webhook: Activate the "Webhook" trigger node. Copy the test or production URL. This URL will be used to trigger the workflow with YouTube video information.
  3. Configure Credentials:
    • Google Gemini: Set up your Google Gemini API credentials in the "Google Gemini" and "Google Gemini Chat Model" nodes.
    • AI Agent: Configure the "AI Agent" node with any necessary API keys or model settings for your LangChain setup.
  4. Customize Shell Command: Adjust the "Execute Command" node to use your preferred tool for downloading YouTube videos and extracting audio (e.g., yt-dlp or youtube-dl). Ensure the command correctly takes the YouTube URL as input and outputs the audio file to a known location.
  5. Adjust File Paths: Update the "Read/Write Files from Disk" node to match the paths where your shell command saves and reads files.
  6. Define AI Agent Prompt: Customize the prompt in the "AI Agent" node to guide Gemini AI on how to structure and write the blog post from the transcribed content.
  7. Define Output Schema: Configure the "Structured Output Parser" node with the desired JSON schema for your blog post output.
  8. Test the Workflow: Send a test request to the webhook URL with a YouTube video URL to ensure the workflow executes as expected and generates the desired blog post content.
  9. Integrate: Connect the output of this workflow to your CMS, blog platform, or other services to automatically publish the generated content.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
