What is Just Prompts?
Just Prompts — Free, guided prompt optimizer that turns basic image ideas into detailed prompts in seconds. Best for Casual AI image generators wanting better prompts without learning prompt engineering, Beginners looking to understand what makes a detailed image prompt, Creators needing fast, structured refinement for quick image ideation. Free to use.
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.
