Convert YouTube videos into blog posts with Gemini API and n8n

Transcript Extraction Prompt (Gemini)

Blog Transformation Prompt (AI Agent)

Building a YouTube-to-Blog Workflow with n8n & Gemini

1. Create a new workflow in n8n and start with the 'n8n Form Trigger' node to receive the YouTube URL input.
2. Add an 'HTTP Request' or 'Google Gemini' node to make a custom API call to the Gemini API.
3. Configure the JSON body in the API call by including the 'file_data' parameter that contains the YouTube URL.
4. Enter a prompt instructing Gemini to generate a 'word-for-word' transcript from the video.
5. Connect the transcript output to an AI Agent node (Claude 3.5 Sonnet or Gemini) for the blog writing process.
6. Set up a System Prompt in the AI Agent node to define the writing style, header structure (H1, H2), and the inclusion of an 'embedded video'.
7. Add an 'Airtable' node and select the 'Create a record' action.
8. Map the markdown output from the AI Agent to the corresponding fields in Airtable.
9. Connect the final result back to the form submission node to display the article to the user immediately.
