How to write a great AI image prompt

The best prompts stack a few clear ingredients. Get these right and almost any tool gives you a strong result:

  • Subject — the main thing, described plainly (“a red fox sleeping in autumn leaves”).
  • Style — photorealistic, cinematic, anime, watercolor, 3D render, and so on.
  • Lighting & mood — golden hour, studio, neon, dramatic. This sets the whole feel.
  • Composition — close-up, wide shot, low angle, symmetrical.
  • Detail words — “highly detailed, sharp focus, 8K” push quality up.

Order matters a little: put the subject first, then style and details. The builder above already arranges them for you.

Tips for each AI tool

  • Midjourney — likes short comma-separated phrases. Control the shape with --ar (aspect ratio) and the model with --v.
  • DALL·E 3 / ChatGPT — prefers natural, descriptive sentences. Just describe the scene and set the size in the app.
  • Stable Diffusion — uses both a prompt and a negative prompt (things to avoid). Quality tags like “masterpiece, best quality” help.

Aspect ratio cheat sheet

RatioBest for
1:1Instagram posts, profile pictures, avatars.
16:9Wallpapers, YouTube thumbnails, presentations.
9:16Reels, TikTok, Stories, phone wallpapers.
4:3Classic photo look, prints.
3:2Standard camera/photography framing.
21:9Ultra-wide cinematic scenes and banners.

What is a negative prompt?

A negative prompt tells the model what to leave out — things like “blurry, extra fingers, watermark, text.” It is mainly a Stable Diffusion feature and is a quick way to clean up common AI mistakes. When you pick Stable Diffusion above, a ready-made negative prompt appears for you to copy too.

Frequently asked questions

What is an AI image prompt?

It is the text instruction you give an AI image generator. A good prompt describes the subject, style, lighting, composition and level of detail, so the model knows exactly what to draw.

How do I make AI images look realistic?

Pick a “photorealistic” style, add lighting like “studio” or “golden hour,” and include detail words such as “sharp focus” and “shallow depth of field.” Avoid mixing too many art styles at once.

Which aspect ratio should I use for Instagram?

Use 1:1 for feed posts and 9:16 for Reels and Stories. The cheat sheet above lists the rest.

Midjourney or DALL·E — which is better?

Both are excellent. Midjourney tends to give a more stylised, artistic look from short prompts, while DALL·E (in ChatGPT) is great at following detailed natural-language descriptions. This builder formats your prompt correctly for either.

Do I need a negative prompt?

Mostly only in Stable Diffusion, where it helps remove common errors. Midjourney and DALL·E usually do not need one.

Are these prompts free to use?

Yes — the prompts this tool builds are yours to use anywhere. You will still need an account with whichever image generator you choose.
