# n8n Workflow: Summarize YouTube Videos from Transcript for Social Media

This n8n workflow automates the process of generating social media summaries from YouTube video transcripts. It allows you to input a YouTube video URL, extract its transcript, and then use an AI agent to create concise, engaging summaries suitable for various social media platforms.

## What it does

This workflow simplifies content repurposing by performing the following steps:

1.  **Triggers on Form Submission**: The workflow starts when a form is submitted, likely containing a YouTube video URL and potentially other details.
2.  **Fetches YouTube Transcript**: It uses an HTTP Request to an external API (likely a YouTube transcript service) to retrieve the full transcript of the provided YouTube video.
3.  **Prepares Data for AI**: A "Set" node (named "Edit Fields") transforms and prepares the extracted transcript data for the AI agent.
4.  **Generates Social Media Summary with AI**: An "AI Agent" node, powered by a "Google Gemini Chat Model", processes the transcript and generates a concise summary optimized for social media.
5.  **Processes AI Output**: A "Code" node further processes the AI-generated summary, potentially formatting it or extracting specific elements.
6.  **Creates Google Doc**: The final summary is then used to create a new document in Google Docs.

## Prerequisites/Requirements

To use this workflow, you will need:

*   **n8n Instance**: A running instance of n8n.
*   **YouTube Transcript API Key**: Access to an API that can extract YouTube video transcripts (e.g., a custom service or a third-party API). You will need to configure the "HTTP Request" node with the correct URL and any necessary authentication.
*   **Google Account**: A Google account with access to Google Docs for storing the generated summaries. You will need to set up Google Docs credentials in n8n.
*   **Google Gemini API Key**: An API key for the Google Gemini Chat Model to power the AI summarization. You will need to configure the "Google Gemini Chat Model" node with your credentials.

## Setup/Usage

1.  **Import the Workflow**:
    *   Save the provided JSON content as a `.json` file.
    *   In your n8n instance, go to "Workflows" and click "New".
    *   Click the "Import from JSON" button and upload the saved `.json` file.
2.  **Configure Credentials**:
    *   **HTTP Request**: Edit the "HTTP Request" node (ID: 19). Update the URL to your YouTube transcript API endpoint and add any required headers or authentication (e.g., API keys).
    *   **Google Docs**: Edit the "Google Docs" node (ID: 495). Click "Create New Credential" or select an existing Google OAuth credential that has access to Google Docs.
    *   **Google Gemini Chat Model**: Edit the "Google Gemini Chat Model" node (ID: 1262). Click "Create New Credential" or select an existing credential for Google Gemini.
3.  **Activate the Workflow**: Once all credentials and configurations are set, activate the workflow by toggling the "Active" switch in the top right corner of the workflow editor.
4.  **Trigger the Workflow**:
    *   The workflow is triggered by an "n8n Form Trigger" (ID: 1225). You will need to access the webhook URL provided by this node (click on the node and find "Webhook URL").
    *   Submit a form to this URL with the necessary data, including the YouTube video URL. The exact payload structure will depend on how the "Edit Fields" and subsequent nodes expect the data. A common structure would be a JSON payload with a `youtubeUrl` field.

This workflow provides a powerful way to automate the creation of social media content from your YouTube videos, saving time and effort in content repurposing.
