I'll be honest about the itch this scratches, because it's a boring problem nobody makes tools for: I got tired of writing prompts.
Not the fun kind, where you’re chasing a specific idea. The other kind. The fifty warmup gens where you just want something in the box so you can test a checkpoint, or a LoRA, or a new sampler — and your brain’s gone blank because you’ve typed “cinematic lighting, highly detailed” four hundred times this week. Batch work eats prompts, and coming up with fresh, varied ones by hand gets old fast.
So I built myself a little thing that hands me a ready-made prompt on tap, and I’ve cleaned it up enough to share. There’s a ComfyUI node and a Forge / Automatic1111 extension. Both do the same job: you pick a subject, and they drop a finished, varied prompt straight into your workflow. Every queue (or every generation) pulls a fresh one, so you’re not staring at the same line twice.
It’s free. You need a free account to get a key, and the free tier gives you 100 prompts a day, which is plenty for normal use — more than I get through most days. It’s SFW only. (If you somehow hammer it, Pro raises the cap, but you’ll probably never hit 100.)
One thing I’ll be straight about: I’m not going to explain how it comes up with the prompts. That’s the part I spent the time on, and it stays under the hood. What I can tell you is what it does — fresh, varied prompts, in either natural-sentence or booru-tag style, as many as you want inside the daily cap.
Using it in ComfyUI
Grab the node: github.com/Stable-yogi/comfyui-stableyogi-prompt — copy the folder into ComfyUI/custom_nodes/ and restart.
Add the StableYogi Prompt node (it’s under the StableYogi category).
Paste your key into api_key once (it saves locally, so you can clear the field after), pick a subject, and wire prompt → CLIP Text Encode.
That’s the whole setup. Every queue outputs a fresh prompt. There’s a trigger input if you want your LoRA/character word prepended, a quality suffix, and a style toggle for sentence vs. tags. No extra Python packages.
Using it in Forge / A1111
Grab the extension: github.com/Stable-yogi/sd-forge-stableyogi-prompt — copy it into your extensions/ folder and restart.
Open txt2img, find the StableYogi Prompt panel, paste your key, hit Save key.
Get prompt drops one into the box. There’s also an auto-fetch toggle that pulls a fresh prompt on every generation (one per image in a batch), plus a session history so you can grab anything good again.
Same subject/trigger/quality/style controls, same daily allowance.
Getting your key
Make a free account then head to Settings → Prompt Engine API. Copy the key, paste it into the node or extension once, done. Your key stays on your machine — it’s never written into your saved workflow or your image metadata.
The honest pitch
It won’t replace a prompt you’ve carefully crafted for a specific vision. That’s not what it’s for. It’s for the other 90% — warmups, model tests, batch variety, breaking a blank-page stall, or feeding a long overnight run something that isn’t the same sentence a thousand times over. That’s the job it does well, it’s free, and if it saves you ten minutes of prompt-fatigue a day, it’s earned its place.
If you try it and something’s clunky, tell me — both repos take issues and I actually read them. Hope it’s useful.
