Show HN: An AI agent that Auto-generates Illustrations for any Blog Post (opens in new tab)

BannerGPT is an AI agent that can auto-generate banner images for any blog post.

The premise is pretty simple. You paste your article into BannerGPT, it analyzes the text and generates a banner image that can complement your article.

Under the hood, the raw post is sent to GPT 3.5 with a prompt to describe a scene that illustrates the main ideas in the text. The description is then sent as a prompt to Stable Diffusion (hosted on Replicate). Finally the title is framed on the image with a nice gradient overlay and turned into a downloadable image.

If you have a personal or company blog, BannerGPT is a nifty little tool that can help add some color to your posts.

Here’s a hosted version to play with: https://bannergpt.dabble.so

I’m curious to see this tested in the wild, so if you share any generated banners in the comments or on twitter I can add them as examples on the site.

This is pretty worth to solve problem! I thought about it many times before when writing an article.

Surely that it is super early phase of development, but if possible, the ability for user to choose the generated art style would be valuable. Oh also, the generated image that contain people face is deformed (common limit of generative image model, if your product can address that, it will be ready to used in commercial, I think).

Thanks for sharing and keep it up!
