What I Built
As someone who frequently writes blogs about AI and programming. I decided to generate an app that uses Google Imagen to generate cover images for my blog posts.
Here is the full user flow:
✍️ The user inputs blog post content
Gemini summarizes the theme and proposes a cover image description
Imagen generates the cover image from Gemini's prompt
The user gets to download or regenerate
Here is the prompt that I used:
Create an app that would allow user to input their blog posts/article as a text input, analyze the information with Google Gemini and decide on an appropriate cover image description for the article, and build that cover image using Google Imagen. Give the user the option to download the image or generate a new image.

Try It Out
Here’s the full source prompt in Google AI Studio:
Launch the App in AI Studio
My Experience
The resulting app was exactly what I wanted, but seeing it being coded by AI in just a couple of minutes - well, that was amazing.
Big thanks to DEV + Google AI Studio for making it easy (and free) to build cool ideas like this. This was a fast project, but one I’ll actually use regularly.
