A small marketing agency used to spend $200 per social media graphic, hiring a designer for each one. They needed about 40 graphics per month across their clients. That's $8,000 monthly just for social media images.

Then one of their team members built an internal app. You type a description like "a cozy autumn coffee scene with warm tones," select a brand template that overlays the client's logo and color scheme, and click generate. Ten seconds later, you have a branded social media image. Need variations? Click again. Want a different style? Adjust the parameters.

Their graphic costs dropped by 80%, and turnaround went from two days to two minutes. The designer on their team shifted to higher-value work like brand strategy. Today you'll build your own image generation app using AI APIs.
