What it does

This workflow performs the following steps:

  1. Triggers on Form Submission: It starts when a user submits a form containing product information.
  2. Extracts Product Image: It takes the provided product image from the form and extracts it into a usable binary format.
  3. Prepares Data for AI: It sets up the necessary data, including the extracted image and product details, to be sent to the Google Gemini AI.
  4. Generates Marketing Content with Google Gemini AI: It sends the product image and details to Google Gemini AI to generate creative marketing ad copy and potentially transformed images.
  5. Processes AI Response: It receives and processes the response from Google Gemini AI.
  6. Converts Generated Image to File: If the AI generates a new image, it converts this binary data into a file.
  7. Returns Results to Form: It populates the original form with the generated marketing ad copy and the URL of the new marketing image.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Google Gemini AI Account/API Key: Access to Google Gemini AI with a configured API key for content generation.
