Prompt Studio is an AI art prompt builder for Stable Diffusion (SDXL / SD 1.5), Flux and Midjourney. First open Settings to enter your API key and model, then describe the image you want in natural language - for example a cyberpunk street at night, neon rain - and the studio merges your description with curated style tags into a production-ready prompt.
Use the platform tabs to switch output formats: Midjourney-style prompts use different phrasing rules than SDXL, so the studio adapts the template automatically. Browse the built-in examples for composition, lighting, camera and style keywords you can remix.
Click Refine to iterate on a result - for instance, ask it to add more dramatic lighting and the prompt is updated in place. Export your best prompts regularly so your work is never lost.
Start from an example close to your goal instead of a blank prompt, then swap the subject and scene words. Save versions as you refine - the best prompt often comes from merging two earlier drafts. Keep a backup of your API key somewhere safe outside the tool.
