Four steps, no manual.

Frequently asked questions.
Is AI Prompt Studio free?
Yes — completely free for everyone. No sign-up, no account and no usage limits.
Is it private? Are my inputs uploaded anywhere?
No. AI Prompt Studio runs entirely in your browser on your own device. The prompt is assembled locally, so your inputs never leave your computer and nothing is uploaded to a server.
Does it work offline?
Yes. Once the page has loaded, building and copying prompts works without a connection because all the logic runs locally. You’ll only need to go online to paste the prompt into the AI tool of your choice.
Which AI tools do the prompts work with?
Image prompts are tuned for Midjourney, DALL·E 3, Stable Diffusion / SDXL and Flux; video prompts for Sora, Runway Gen-3, Google Veo, Pika and Kling; business-copy briefs work in ChatGPT, Claude, Gemini or any chat model. Pick the target tool and the prompt is formatted to match.
What is a negative prompt, and when do I use it?
A negative prompt lists what you don’t want in the image — blur, extra fingers, watermarks, artefacts. It’s used by Stable Diffusion and SDXL, so the studio only shows it on the Image tab when you pick the SDXL target tool. Copy it into the model’s dedicated negative-prompt field.
Do I need an account or to install anything?
No. Just open the page and start building. There’s nothing to install and no account to create — the tool is ready the moment it loads.
