Hundreds of prompts, one click
Load a prompt file and press Start. Three jobs run at once with safe spacing, the queue pauses when your fast hours run out, and failed jobs are rerun on their own.
Let any AI write the prompt file
Copy our instructions into ChatGPT, Claude or Gemini, describe your series in one sentence and paste the answer back. YAML, CSV, JSON or one prompt per line all work; errors come with a one-click fix request.
Every image under the right name
No more 0_1.png. Each image is matched to the exact prompt that made it and saved into its own folder. Unsure matches are kept apart in _unmatched rather than mislabelled.
Save a whole page in one go
Archive, folders, profiles, Explore: collect the images on a page, or let the extension scroll for you, Shift-click a range and save them all, each with its full prompt as a Markdown note.
One idea, a whole series
Variables, random pools and repeats turn one prompt into every version you want. Set --ar, --v or --sref once for the whole run, and see how many jobs and images it makes before you start.
About Prompt Automation for Midjourney
Prompt Automation is a Chrome extension for people who make images with Midjourney in volume. Load a prompt file and press Start: it types each prompt into your own signed-in Midjourney tab, a few at a time, waits for the result and downloads every image under the title of the prompt that made it.
Matching uses Midjourney's own data, not guesswork, so a picture never ends up under someone else's name. When it cannot be sure, the image goes to an _unmatched folder instead. A _prompt.md beside each set keeps the full prompt and parameters.
It is an independent tool and is not affiliated with Midjourney, Inc. It uses your own Midjourney subscription, and your prompt files, settings and images stay on your computer.
Pricing
Every install starts with a 7-day free trial of everything.
Saving the single image you are viewing is free, always. One license key works on up to 5 browsers.
