New WordPress Plugin: Cover Artist (AI-generated blog graphics and posts)

I made a WordPress plugin about a year ago, and just published it to the WordPress directory. It’s called Cover Artist, and I used it to generate the cover art for this blog post! You’ll be able to get it here once it’s approved: Cover Artist (this is still pending; last checked December 10, 2025).

Cover art is one of those types of artwork that I typically get from stock image depositories. Occasionally, I’d make cover art myself using something like Preview or Google Slides, because I’m lazy.

But when image generation tools started becoming available, I started using them for my cover art. First Midjourney, then Flux, then OpenAI’s Dall-E, and now Google’s Nano Banana.

So I made a plugin that automates many parts of the image generation journey. The Cover Artist plugin

1. Analyses what your post is about – reading the title and contents, and creates a summary of what good cover art should contain (you can overwrite this with your own content)
2. Creates an image using an image generation engine and downloads it
3. Compresses the image
4. Gives it an SEO-friendly file name
5. Gives it SEO-friendly alt text

The image is then ready to use in your media library. Bam!

I’m keeping this plugin simple, so I’m restricting support to two engines: OpenAI and Google, as it’s hard to keep up with API specs as they evolve rapidly.

I have also extended it to be able to create entire posts for you, including images. Here’s an example of a post I just created.

Here’s the post that that process created:

Frankly, that post is so milquetoast (it was built with gpt-5-nano!) that I can’t bear to publish it, but you get the idea. AI is never a good writer, but it does create a framework upon which you can expand.

At present, Cover Artist is open source, and you have to supply your own API keys. This keeps costs down for you (about 10-15c per image), but it’s fiddly and a bit cumbersome — not everyone wants to go get their own API key.

In a future version, I’ll let you buy image generation credits, if people will use that.
