🤖 AGENT OF THE WEEK
Generate images like this using the agent!
This guide walks you through building an ad creator agent that turns any single image (product shot, poster, or ad) into dozens of marketing variations with one click. Using n8n, Airtable, and Nano Banana, you’ll create an assistant that creates and manages ad creatives at scale, all from inside Airtable.
Step-by-Step:
Open up n8n: Create a new workflow (free account lasts 2 weeks!)
Import pre-built agents template: Plug in the n8n + Airtable template provided
Connect your tools: Link Airtable, Google Nano Banana (via OpenRouter), and your preferred LLM (like GPT-4.1)
Drop in an image: Upload any product photo or ad into Airtable sheet
Set your prompts: Fill out fields like style, lighting, or text (or auto-generate them with ChatGPT)
Run it: Hit the Airtable button → n8n creates as many image variations as your would like and stores them right into your table row
Bonus: We’ve put together a detailed video walkthrough and the exact n8n agent template. Access both in our Building AI Agents Community here!
