About Just Prompts
Just Prompts is a free, minimalist web tool that refines your AI image generation prompts through a guided 'additive prompting' technique. Instead of starting from scratch, you answer two core questions—what is your subject and how do you want the image to look?—and the tool iteratively enhances your input to produce a more detailed, higher-quality prompt in seconds. The tool is designed for anyone who uses AI image generators (like DALL·E, Midjourney, Stable Diffusion) but struggles to craft effective prompts. It walks you through a structured process that adds layers of specificity without requiring deep prompt engineering knowledge. What sets Just Prompts apart is its simplicity and focus: no sign-up walls, no complex settings—just a clean interface that transforms basic ideas into production-ready prompts. Created by @nickfloats and @SanxRoz, it emphasizes speed and accessibility for casual creators and power users alike. At its core, Just Prompts is not a generator itself but a prompt optimizer. It works by asking targeted questions and then applying best-practice structures (style, lighting, composition, mood) to your original input. The result is a fully formed prompt you can copy and paste into your preferred AI image tool. It's web-based, works in any browser, and is mobile-friendly—ideal for quick ideation on the go. Compared to alternative prompt tools, Just Prompts offers a more guided additive approach but zero integrations, making it a focused utility rather than a full workflow platform.
Behind the Verdict
Just Prompts nails the essentials of a prompt optimizer: it’s free, fast, and requires zero signup, letting you get from a vague idea to a detailed, copy-paste-ready prompt in under a minute. The guided two-step flow is ideal for beginners who are overwhelmed by blank prompt boxes, and the additive prompting methodology—building up your prompt by layering specificity—is a proven technique for getting better results out of models like DALL·E, Midjourney, and Stable Diffusion. The output structure, which covers style, lighting, composition, and mood, ensures you don’t forget the details that matter. That said, the tool is intentionally bare-bones. There are no integrations, no saved history, and no batch processing, so you’re limited to one prompt at a time and must manually copy your output to your generator of choice. For a casual creator who makes images occasionally, this friction is negligible. But if you’re a power user who iterates on many prompts daily, you’ll likely outgrow it quickly and may prefer a tool like PromptBase, which offers prompt marketplaces and libraries, or Lexica, which integrates search and generation. Another consideration is that the tool is only as good as the questions it asks. While the guided approach lowers the barrier, advanced prompt engineers who are already comfortable with structured prompts might find the rigid flow restrictive. However, for its target audience—people who want better prompts without studying prompt engineering—Just Prompts is a delightful, no-strings-attached utility. It’s also a great educational tool: by seeing how your initial idea gets expanded, you inadvertently learn what makes a prompt effective.

Real-world workflow fit
Concrete scenarios for the personas Just Prompts actually fits — and what changes day-one when you adopt it.
You’re a hobbyist who uses Midjourney occasionally and always get mediocre results. You open Just Prompts, type 'a castle', answer two questions about subject and look, and within seconds get a detailed prompt like 'a majestic stone castle perched on a cliff, bathed in golden hour light, with dramatic clouds and a foreboding atmosphere.' You copy it and paste into Midjourney, immediately seeing
Outcome: You produce a high-quality image in your next generation, with minimal effort and no need to learn prompt engineering.
You’re a content creator who needs quick visuals for social media posts. You use Just Prompts on your phone to generate a product shot prompt for a flat lay, specifying 'clean white background, soft natural lighting, minimal composition, happy mood.' You copy the result into DALL·E and get a usable image for your post.
Outcome: You save time on prompt tweaking and get a polished visual that fits your brand aesthetic.
You’re new to AI image generation and want to understand what makes a good prompt. You use Just Prompts repeatedly with different subjects, observing how it adds style, lighting, and composition details. After a few uses, you start crafting better prompts on your own.
Outcome: You quickly learn prompt structure through hands-on iteration, improving your skills beyond the tool.
Use Cases
- Refine a vague concept like 'a cat' into 'a fluffy orange tabby cat lounging on a velvet chaise in golden hour light'
- Generate a detailed prompt for a fantasy landscape artwork in seconds
- Quickly create a prompt for a product photography scene with controlled lighting and mood
- Improve prompts for character designs by specifying style, expression, and background
- Iterate on an existing prompt by answering additional questions to add depth
Limitations
- The live site evidence is minimal—just a header, a "Get your key here" key field, a save action, and "Additive Prompting" branding by @nickfloats and @SanxRoz.
- The evidence designates no underlying AI model, and it references a user-supplied key rather than a documented product API.
- What model or provider the user's key unlocks is not stated in the provided pages.
