AI-Powered Product Image & Marketing Campaign Generator

This n8n workflow automates the generation of professional product images and marketing campaign text using AI, triggered by a simple form submission. It streamlines the creative process for marketing teams, allowing them to quickly generate diverse content based on product descriptions.

What it does

This workflow simplifies the creation of marketing assets by:

1. Receiving Product Information: It starts by accepting product details (like product name and description) via an n8n form submission.
2. Generating Image Prompts: An AI Agent processes the product description to generate multiple detailed prompts for product image generation.
3. Generating Marketing Campaign Text: Concurrently, the AI Agent also generates compelling marketing campaign text based on the product description.
4. Creating Product Images: For each generated image prompt, it sends a request to an external AI image generation API (e.g., DALL-E, Midjourney, Stable Diffusion via an HTTP Request node) to create the actual product image.
5. Storing Generated Images: The generated images are converted to files and then uploaded to Google Drive for easy access and organization.
6. Providing Output: The workflow provides the generated image URLs and marketing text as its final output.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance.
• OpenAI API Key: For the "OpenAI Chat Model" node within the AI Agent.
• AI Image Generation API: Access to an AI image generation service (e.g., DALL-E, Midjourney, Stable Diffusion) with an API endpoint that can be called via an HTTP Request.
• Google Drive Account: For storing the generated images.
• Google Drive Credentials: Configured within n8n.

Setup/Usage

1. Import the Workflow:
   • Download the provided JSON file.
   • In your n8n instance, click on "Workflows" in the left sidebar.
   • Click "New" and then "Import from JSON".
   • Paste the JSON content or upload the file.
2. Configure Credentials:
   • OpenAI Chat Model: Click on the "OpenAI Chat Model" node. You will need to set up an OpenAI API credential.
   • Google Drive: Click on the "Google Drive" node. You will need to set up a Google Drive credential.
   • HTTP Request: Click on the "HTTP Request" node. This node is currently configured as a placeholder. You will need to configure it to connect to your chosen AI image generation API. This will likely involve:
     • Setting the URL to your image generation API's endpoint.
     • Setting the Method (e.g., POST).
     • Adding Headers (e.g., Authorization: Bearer YOUR_API_KEY).
     • Configuring the Body with the prompt and any other required parameters (e.g., image size, number of images). The prompt should come from the output of the "AI Agent" node (e.g., {{ $json.imagePrompts }}).
3. Activate the Workflow: Once all credentials and configurations are set, activate the workflow by toggling the "Active" switch in the top right corner.
4. Trigger the Workflow:
   • Open the "On form submission" node.
   • Copy the webhook URL provided.
   • Access this URL in your browser or use a tool like Postman to send a POST request with a JSON body containing productName and productDescription fields.
   • Example JSON body:

     {
       "productName": "Eco-Friendly Water Bottle",
       "productDescription": "A durable, insulated water bottle made from recycled materials, perfect for outdoor adventures and daily hydration. Keeps drinks cold for 24 hours and hot for 12 hours."
     }
     

5. Monitor Output: After triggering, the workflow will run. You can view the execution results in n8n, and the generated images will appear in your configured Google Drive folder. The final output will include the generated image URLs and marketing campaign text.
