Promptnomicon turns your simple ideas into detailed, model-optimized prompts for Midjourney, Flux, and Stable Diffusion. Each model speaks its own language — what works in Midjourney fails in SD. Promptnomicon knows the difference. Describe what you want to create, pick your model, and get a structured prompt with style, lighting, composition and technical parameters. Includes a free tier and an "Arcane mode" for darker, more atmospheric creations.








How does the free tier actually work — is there a daily cap on prompts or some kind of watermark on the output, and what unlocks when you move to a paid plan?
@sezer417496 The free tier has a prompt limit (10 per month, not per day—I want to be transparent about that), and there are no watermarks or anything like that, since it's just plain text: you create your prompt, copy it, and can use or modify it however you like. The advantage of the paid option is simply that you can access "forbidden" mode, which unlocks NSFW prompt generation for models that support it. And it’s not really a subscription plan, but rather a token-bundle system where you buy tokens (you can purchase blocks of 50 or 100); they don't renew automatically, but they don't expire either. You only have them when you actually want them.
how well does the free tier actually hold up, like how many prompts a day and is there a watermark or anything on the outputs?
@rfanilkayaflsm Good question! The free plan includes 10 "spells" per month (not per day—I want to be transparent about that). Each spell consists of a complete, structured prompt for the model of your choice, and the results come without watermarks or extras: the prompt is plain text—you copy it, and it’s yours. They don’t expire, either: unused free spells simply reset each month, and if you buy a package, those never expire (no subscription required). If 10 a month seems too few for your workflow, that’s exactly the kind of feedback I’m looking for, so let me know!
Tried it with a quick flux test this morning and was surprised how spot-on the lighting tags were without me having to spell them out. Arcane mode is genuinely fun too.
@burcu192820 Thank you so much! You made my day! Lighting was actually one of the things I thought about most when fine-tuning the instructions for Flux: the model interprets descriptive prose so well that most people don't get the most out of it by sticking to lists of keywords; that’s why the tool focuses on full scene descriptions, including the lighting. I’m really glad the "Arcane" mode worked well, too 😄 Just out of curiosity, what kind of scene did you try? I love creating prompts for situations where the lighting plays a starring role.
