Prompt Silo
A free categorized MidJourney prompt library with Discord copy buttons and a live parameter reference.
For MidJourney users who keep drawing a blank on subject words, Prompt Silo is a quick win — the categorized lists plus a live parameter reference beat digging through Discord docs. Free, and the multi-target copy buttons cover more than Discord. Just don't mistake it for a prompt generator or a modern app; the interface is dated and the ads and affiliate links are dense.

Skip Prompt Silo if you need an actual image generator, dynamic variable substitution, an API, or a saved prompt library — it only assembles prompt text you then run elsewhere.
The free tier is genuinely free, but the ChatGPT copy target only works if you separately pay OpenAI $20/mo for a ChatGPT Pro account to run Pheeds Custom GPTs.
Prompt Silo's free tier is the whole story for most solo MidJourney users — you get the subject library, the full parameter list and every copy target at $0/mo. The VIP tier is bundled inside the Kings & Queens of Content membership rather than sold as a standalone upgrade, so price it against the membership. Cheaper than a paid prompt-marketplace subscription if you only need subject words; not a replacement for an image generator.
In short
Prompt Silo — A free categorized MidJourney prompt library with Discord copy buttons and a live parameter reference. Best for MidJourney beginners who want ready-made subject words instead of writing prompts cold, Print-on-demand sellers needing repeatable product prompt templates, Content creators who want to copy a finished /imagine prompt straight into Discord. Free to use.

About Prompt Silo
Prompt Silo is a free, ad-supported MidJourney prompt assembly page from Kurt Melvin at Pheeds.com. Instead of writing subject words from scratch, you pull them from structured lists — Nature, Trees Plants and Flowers, Wood and Paper, Metals, Gemstones, and more — then assemble a full /imagine prompt in one text box. Type one subject per line, click through preset flags, and hit a copy button. The parameter list covers aspect ratios from --ar 1:2 to --ar 21:9, quality presets at 0.25, 0.5, 2 and 5, stylize up to 60000, chaos at 1/50/100, seed and sameseed, --no, --stop, --tile, --video, --v 5 / --v 5.1 / --v 5.2 / --v 6 --style raw, plus --niji 4 and --niji 5, and a blend option for merging subjects. Copy targets go wider than Discord: MJDisc, PheedsDisc, Your MJ and MJ All, plus Stable Diffusion, PlayGround, Leonardo, BlueWillow, Futurepedia, HOFv3, HOFv4 and ChatGPT via Pheeds Custom GPTs (those need a $20/mo ChatGPT Pro account on OpenAI's side). Command presets cst1 through cst20, repeat, perm and permv let you reuse parameter combinations. Understand what this is: a prompt assembly and reference page, not an image generator — you still need a MidJourney or other image subscription to render anything. The free tier covers the library, parameter list, commands and every copy target. The VIP version, part of the Kings & Queens of Content membership, adds a paint-by-numbers prompt system for designing printed products, a public domain resource library (including the 2025 roundup of characters, films, books and music entering the public domain), VIP forum access and a Pheeds affiliate program paying up to 60%. Closest alternatives are the MidJourney docs, Lexica, and prompt-marketplace tools with dynamic variable substitution.
Behind the Verdict
Prompt Silo earns its keep as a reference page. The categorized subject library is the real value: hundreds of nature, tree, flower, metal and gemstone terms you can pull one per line into a build box instead of inventing words on the spot. The parameter list doubles as documentation — if you want to know what --stylize 60000 or --chaos 50 actually does before committing it to a prompt, this page shows it as a clickable flag rather than buried prose. Copy targets are broader than most prompt helpers: MJDisc, PheedsDisc, Your MJ and MJ All for Discord, plus Stable Diffusion, PlayGround, Leonardo, BlueWillow, Futurepedia, HOFv3, HOFv4 and ChatGPT. Command presets cst1 through cst20 let you reuse parameter blocks, which saves retyping on repeated jobs. Be clear-eyed about what it can't do. It never renders an image — you still pay MidJourney or another service. There is no prompt history, no saved prompt sets, no variable substitution, no API. The design is dated and the page carries ads and affiliate links throughout, so it reads more like a 2010s marketing site than a modern tool. The ChatGPT handoff only works if you separately pay OpenAI for a $20/mo ChatGPT Pro account to run Pheeds Custom GPTs. Where it fits: beginners who want ready-made subject words, print-on-demand sellers who need repeatable product prompt templates, and hobbyists who prefer curated lists over browsing galleries. Where it doesn't: teams needing shared workspaces, developers wanting a programmatic prompt builder, or anyone who needs dynamic generation across many variants. The VIP tier adds a paint-by-numbers product prompt system and a public domain library — genuinely useful if you're making printed goods, less so if you just want /imagine strings.

Real-world workflow fit
Concrete scenarios for the personas Prompt Silo actually fits — and what changes day-one when you adopt it.
You open Prompt Silo, click 'Nature', paste six subject words one per line, select --ar 16:9 and --v 6 --style raw, then hit MJDisc.
Outcome: A complete /imagine prompt lands in your Discord channel ready to send, with no trips to the MidJourney docs.
You reuse a saved cst preset for poster layouts, swap the subject lines for a new design, and copy into MJ All.
Outcome: Repeatable prompt templates that keep your product designs stylistically consistent across a catalog.
You look up what --stylize 60000 or --chaos 50 does on the parameter list, click each flag to build a test prompt, and compare outputs.
Outcome: You learn parameter behavior hands-on instead of guessing, then save the combination as a cst preset.
Use Cases

Where the pricing makes sense
The company stage and team size where Prompt Silo's pricing actually pencils out — and where peers do it cheaper.
Prompt Silo's free tier is the whole story for most solo MidJourney users — you get the subject library, the full parameter list and every copy target at $0/mo. The VIP tier is bundled inside the Kings & Queens of Content membership rather than sold as a standalone upgrade, so price it against the membership. Cheaper than a paid prompt-marketplace subscription if you only need subject words; not a replacement for an image generator.
Setup time & first value
How long it actually takes to get something useful out of Prompt Silo — broken out by persona, not the marketing-page minute.
First value in under two minutes: the free page loads with the subject library and parameter list already open, so you can paste subjects and copy a prompt on the first visit. No account, no onboarding. Learning the full flag set takes longer — budget an hour to internalize aspect ratios, stylize ranges and version flags.
Switching to or from Prompt Silo
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From MidJourney Discord docs: paste your prompt idea into Prompt Silo's subject lines and click the flags instead of reading reference pages and typing flags by hand.
- →From a notes app prompt file: replace your running text file with Prompt Silo's subject-per-line box and cst1-cst20 command presets.
- →From Lexica-style gallery browsing: switch to curated subject word lists when you want to direct the prompt yourself rather than copy someone else's.
- ↗To a dynamic prompt tool with variable substitution: move out when you need programmatic variants rather than one prompt at a time.
- ↗To a saved prompt library or automation platform: move out when you need history, sharing or workflow automation Prompt Silo doesn't offer.
