How does it work?

1. You submit the form with your reference image, company name, and selected "Creative Recipe."

4. Fal.AI generates the images using the fast and efficient Nano Banana model.
5. The results are saved directly to your Google Drive output folder.

• Fal.AI API Key: For generating the images (ensure you have credits).
• A Google Drive Folder: One for inputs and one for outputs.

💰 Estimated Costs

Important: The Prompt Strategy

This automation doesn't just copy your image. It uses a specific instruction to "Describe the image extremely comprehensively. don't leave anything behind". This ensures GPT-5.1 captures every visual detail—lighting, composition, and mood—before rewriting it into new creative angles.

That’s it! Just fill the form and let the automation build your ad campaign.
