The three-step production workflow for making 150 ads in a day.

From the GTM Asset Creation With AI series by Hanna Huffman at Marketer in the Loop

Overview

This workflow turns strategic preparation into finished ads at volume. It works because every creative decision was already made upstream (positioning, brand guide, copy bank, component library). Assembly is just combining ingredients.

Three steps. Three tools. One day.

Prerequisites

Before you start, you need these completed:

• [ ] Campaign brief (GACCS format — goals, audience, creative direction, channels, success metrics)
• [ ] Copy bank (50-100+ validated headline/subheadline pairs, organized by persona and wedge)
• [ ] Brand guide / design tokens (colors, fonts, textures, spacing documented)
• [ ] Component library (logos, icons, textures, screenshots, photography — all in one folder)
• [ ] Shot list (30-35 background image descriptions tied to campaign strategy)

If any of these are missing, go back and build them first. Skipping prep is why most people's AI-generated ads look generic.

Step 1: Generate Text Overlays

Tool: ChatGPT (or Claude — ChatGPT tends to be more compliant for this specific task)

Time: 1-2 hours
