Batch Generate Image with any AI

Batch Generate Image with any AI is a lightweight Windows desktop app by 3thousand30 for generating batches of AI images from a simple image list — posters, social media graphics, book illustrations, invitations, product shots, album art, and more.

You bring your own API key (BYOK). The app connects directly to your chosen AI provider, saves outputs locally to your PC, and does not run a subscription cloud in the middle.

Get it on Microsoft Store

How it works

Configure your persona — define the visual direction applied to the whole batch
Load style references (optional) — pick a folder and click Analyze to extract shared visual cues
Prepare your image list — load a CSV or YAML file, or generate a CSV inside the app
Generate — preview the prompt, choose the template and output folder, then save the full batch locally

The app is built for repeatable image work, not one prompt at a time.
