Automating Blog Post Images with ChatGPT’s New Image Model + Notion + Zapier

Here's how it works:

1. Write Blog Content in Notion

2. Auto-Generate an Image Prompt

We added a Notion AI property to each post that automatically suggests an image generation prompt. Based on the blog content and aligned with our brand guidelines, it creates prompts that ensure images match the spirit of each article—without requiring human intervention.

It might seem counterintuitive, but using AI to write AI prompts is incredibly effective.

3. Trigger the Image Creation with a Button

4. Zapier Handles the Magic Behind the Scenes

The Zap does the following:

• Pulls the AI-generated prompt from Notion

• Sends the prompt to ChatGPT's image generation API

• Receives a beautiful, AI-generated image back in base64 format, and converts it to a usable image file via another service I just discovered, called Cloudinary

• Finally, saves the Cloudinary URL back into a "Cover Image" property in our Notion database, since Notion's API doesn't allow direct cover image updates

Why We Love This Setup

• It's Seamless: Writers don't have to leave Notion or think about images anymore.

• It's Fast: From click to image, the whole process takes about a minute.

• It's On-Brand: By customizing the prompt generation, the resulting images stay consistent with our aesthetic.

• It's Scalable: As we publish more frequently, our team won't be bottlenecked by manual design work.
