AI Image Prompt Generator
Describe the picture you want and get a prompt shaped for the image model you use. Choose the style – photo, cinematic still, illustration, watercolour, 3D, anime, flat vector and more – the framing, lighting, mood and colours, a camera and lens for photographs, extra details and things to avoid. The output follows each tool’s conventions: Midjourney parameters such as --ar and --no, a separate negative prompt for Stable Diffusion, or a natural description for DALL·E and GPT image models.

AI Image Prompt Generator FAQ
Why do models need different formats?
Midjourney reads parameters, Stable Diffusion uses a separate negative prompt, and DALL·E prefers natural sentences.
What is a negative prompt?
A list of things the image should not contain, such as text or watermarks.
Can I copy an artist’s style?
Check your platform’s rules and respect living artists’ work.
Are real people allowed?
Many platforms forbid images of real people without consent.
Writing image prompts
Image models respond to concrete visual words: the subject, the camera’s position, the light and the medium. Abstract words like “beautiful” add little.

This tool does not call an AI model. It turns your answers into a well-structured prompt in your browser, so it costs nothing, works offline once loaded and never sends your text anywhere. Paste the result into ChatGPT, Claude, Gemini, Copilot or any other assistant, or into the system message of an API call.
Good prompts are specific about the task, the context the model cannot know, the audience and the shape of the answer. The fields on this page cover exactly those parts; leave optional fields empty when they do not apply, and the prompt stays short.
Review the answer you get: language models can be confidently wrong, especially about facts, numbers, names and recent events. Ask for sources or mark claims to check, and keep personal or confidential data out of prompts unless your organisation allows it.
Keep the prompts that work. A small library of tested prompts – with a note on which model and settings they were used with – saves time and makes results more consistent across a team. The other prompt tools on this site help you format, template, fill and measure them.
