Google Nano Banana does a great job generating single static ads, but if you need to produce thousands of ad variations in bulk, manual operations quickly become impractical.

This AI workflow built with n8n solves the problem:

1. Upload product reference images to an n8n form

2. OpenAI Vision automatically analyzes product features

3. An AI agent generates customized image prompts (quantity customizable)

4. Nano Banana generates static ad images on demand

5. Finished products are automatically stored on Box.com for instant access

The entire process is fully automated, requiring zero manual intervention once set up. Need 50, 100, or even 1,000 ad variations? Just enter a number in the form.

Interestingly, a commenter mentioned, "No need to pay $40/month—you can achieve this with existing tools and a simple script." The author's response, "What $40?" implies there are no additional costs for this solution.

If you're already using n8n, this template effectively amplifies Nano Banana's single-output capability by 1,000x. However, judging from the replies, accessing the template requires engaging with the tweet first—a classic growth hacking tactic that feels very authentic.
