How to Run Hundreds of Midjourney Prompts in Bulk

Short answer: Midjourney has no "upload a list" button. On its website you paste prompts one at a time, and each plan can run only a few jobs at once. Its built-in batch tricks, --repeat and permutation prompts, work only in Fast or Turbo mode, so they spend your Fast hours and can't run in Relax. To run a long prompt list you can paste in rounds by hand, use those built-in tricks within their limits, or use a browser extension such as MidBot, which submits a prompt file on Midjourney's website and downloads every image as it finishes. Before you automate anything, know that Midjourney's terms restrict automated tools (details below).

How Midjourney handles many prompts today

Midjourney runs "jobs". Each prompt you submit is one job, and an image job normally returns a grid of four images. How many jobs you can run, and how fast, depends on your plan and your speed mode.

Speed modes: Fast, Relax and Turbo

Midjourney also gives heavy Relax users a lower spot in the queue, so the more you use Relax in a month, the longer each job can wait.

Plans at a glance (2026)

Unused Fast hours don't roll over.

Two facts sellers often miss:

• On Basic and Standard, your images and prompts are public by default, and other members can see and remix them. Only Pro and Mega include Stealth mode, and it only hides images made after you switch it on.
• If your company earns more than $1,000,000 a year, Midjourney's terms require a Pro or Mega plan.

Option 1: Paste prompts in rounds (free, fully manual)

Keep your prompts in a text file, paste a few at a time up to your plan's concurrent-job limit, wait for them to finish, and paste the next few.

• Good for: up to a few dozen prompts, or work where you want to watch every result.
• Downsides: it doesn't scale. At 600 prompts it becomes a whole evening of paste, wait, download, repeat. You also have to download or organise results yourself (the website lets you select several images, or a whole folder, and download them).

Option 2: Use --repeat and permutations (built in, Fast hours only)

Midjourney has two native ways to make many jobs from one prompt:

• --repeat (or --r) runs the same prompt several times. Limits by plan: Basic 2–4, Standard 2–10, Pro and Mega 2–40.
• Permutation prompts use curly braces to make variations, for example a {red, blue, green} ceramic mug on a white table, which becomes three jobs.

• Good for: exploring variations of one idea quickly.
• Downsides: both run only in Fast or Turbo, so every job spends Fast hours, and neither works in Relax. They also only vary one prompt. They can't run a list of 600 different prompts. If you add --repeat to a permutation prompt, the permutations are ignored.

Option 3: "Midjourney API" services (unofficial)

Midjourney has no official public API. Services that sell one are unofficial wrappers that drive an account for you.

• Good for: developers building apps who accept the risk.
• Downsides: they need code, they cost extra, and they sit squarely inside what Midjourney's terms prohibit. Users of these services have reported bans with the message "You have been blocked from Midjourney due to accessing our services via automation, scripting, or third party tools."

Option 4: Run your prompt list with MidBot

MidBot is a Chrome extension from Extino. You open Midjourney's website, load your prompt file into MidBot's side panel, choose Fast, Relax or Turbo, and press start. It submits each prompt in turn, watches progress, and downloads every finished image into named folders on your computer, with a CSV log of each prompt, image link, timestamp and status.

Other features, per the store listing: prefix and suffix text added to every prompt, adjustable delays and scheduled breaks, auto-resume after a network drop, optional image-to-video animation, and a prompt generator that turns keywords into prompts using Google Gemini (this needs your own free Gemini API key).

• Good for: stock contributors, print-on-demand sellers, agencies and anyone with long prompt lists, especially overnight in Relax mode.
• Downsides, honestly: it needs an active Midjourney plan, and Relax needs Standard or above. It can't make Midjourney faster than your plan allows, so Relax runs still wait in Midjourney's queue. Extino's site describes runs of 25,000+ images, but your real pace is set by your plan and mode. It's Chrome only. It's a paid tool after a 24-hour free trial. And it is automation, so Midjourney's rule on automated tools applies (next section).

Comparison

Is automating Midjourney allowed?

This is the question to ask about any tool, including ours, so here is the plain answer.

Midjourney's Terms of Service say: "You may not use automated tools to access, interact with, or generate Assets through the Services." They also say Midjourney "reserves the right to suspend or ban your access to the Services at any time, and for any reason."

What that means for you:

• Any tool that submits prompts for you, including MidBot, is the kind of tool that rule covers.
• Nobody can honestly promise an automation tool is "ban-proof" or "undetectable". We don't.
• If your Midjourney account is important to your income, weigh that risk before you automate it.

What we can say about MidBot specifically: it runs inside your own logged-in Chrome, on your own Midjourney plan, with no Midjourney API key. Images download to your own computer. Its Chrome Web Store listing discloses that it handles authentication information, personal communications and website content, and says that data isn't sold or used for unrelated purposes.

MidBot is an independent tool and isn't affiliated with or endorsed by Midjourney.

How to run a prompt list with MidBot, step by step

1. Install MidBot from the Chrome Web Store and pin it to your toolbar.
2. Log in to midjourney.com in the same Chrome browser with your paid Midjourney account.
3. Open the MidBot side panel from the toolbar icon while you're on Midjourney's site.
4. Load your prompts. Drag your prompt file into the panel. Or use the AI tab to generate prompts from keywords (needs your own Gemini API key).
5. Add a prefix or suffix if every prompt needs the same settings, for example --ar 2:3 --v 7.
6. Choose a speed mode. Relax for big, non-urgent batches (Standard plan or above); Fast when you need results now.
7. Set delays and breaks that suit your plan.
8. Press Start and let it run. Progress shows in the side panel.
9. Collect your files from the download folder, and export the CSV so every image can be matched to its prompt.

Prep your prompt list so a big batch works first time

• One prompt per line, no blank lines, no numbering.
• Put shared settings in the suffix, not in every line, so you can change aspect ratio for the whole batch in one place.
• Test 10 prompts first in the mode you'll use, then run the rest.
• Keep prompts unique. A list of near-duplicates wastes jobs; permutations are cheaper for simple colour or size variations if you're on Fast anyway.
• Name the batch (for example mugs-oct-relax) so the download folder and CSV make sense later.
• Check your plan's privacy. If the designs are for sale and you're on Basic or Standard, remember they're public.

Frequently asked questions

Can you run multiple prompts at once in Midjourney? Yes, up to your plan's concurrent-job limit, but you still submit each prompt yourself. There's no built-in way to upload a list of different prompts.

Does --repeat work in Relax mode? No. Per Midjourney's Help Center, --repeat and permutation prompts only run in Fast or Turbo mode, so they use Fast hours.

How many times can I use --repeat? Basic 2–4, Standard 2–10, Pro and Mega 2–40 repeats per prompt.

Is there an official Midjourney API? No. Services selling a "Midjourney API" are unofficial and fall under Midjourney's restriction on automated tools.

Is automating Midjourney against the rules? Midjourney's Terms of Service say you may not use automated tools to access, interact with, or generate assets through its services, and it can suspend accounts at any time. Weigh that before using any automation tool.

Are my Midjourney images private? Not by default on Basic or Standard. Images and prompts are public unless you use Stealth mode, which needs a Pro or Mega plan.

Does MidBot need a Midjourney API key? No. It works through Midjourney's website in your own logged-in browser. It does need an active Midjourney subscription, and its optional prompt generator needs your own free Gemini API key.

Can MidBot run in Relax mode overnight? Yes. MidBot supports Fast, Relax and Turbo. Relax needs a Standard, Pro or Mega plan, and each job still waits in Midjourney's Relax queue.

Try it on your next list. If you have more prompts than patience, MidBot on the Chrome Web Store has a 24-hour free trial, so read Midjourney's terms, test it on ten prompts, and decide for yourself. And if your batches are small, pasting in rounds or a quick --repeat is all you need.
