Generate consistent styled images from references with Google Gemini and Sheets

Who’s it for

This workflow is designed for creators, designers, and automation builders who need to generate visually consistent images at scale. It is ideal for teams producing branded visuals, social media assets, or AI-generated images where preserving a recognizable visual style is important.

If you already manage prompts and image references in Google Sheets and want a repeatable, automated image generation pipeline, this template is a good fit.

How it works / What it does

The workflow is triggered via a webhook and reads pending image generation tasks from a Google Sheet. For each row, it downloads a reference image and analyzes its visual characteristics using Google Gemini, including color palette, composition, and overall artistic style.

Using this analysis, Gemini generates a new image that follows the same visual style while applying your provided prompt. The generated image is uploaded to Google Drive, and the original Google Sheet is updated with the result or an error message.

Real-time status updates are sent during execution using ntfy.sh notifications.
