Prompt tips
Six habits that make an image prompt easier for a model to follow. They apply whether you write the prompt by hand or start from this generator.
Be specific
Swap general words for concrete ones. “A weathered wooden door” gives a model far more to work with than “a door”.
Describe the subject
Say what it is, what it is made of, its condition, and what it is doing. Materials and surfaces matter as much as the object itself.
Add the environment
Place the subject somewhere. Indoors or outdoors, time of day, weather and background all change the result.
Specify lighting
Lighting sets the mood faster than any adjective. Name the source, direction and softness — soft window light, hard side light, neon glow.
Mention camera and composition
Framing, angle and lens change the whole image. A 24mm low-angle shot and an 85mm close-up describe two different pictures.
Add mood and style
Finish with the feeling and visual direction, and keep it short. Two or three style words work better than a long stack of them.
Frequently asked questions
Does this tool create the image as well?
No. This AI image prompt generator writes prompt text only. Copy the finished prompt and paste it into whichever image-generation platform you already use — that platform produces the image.
Do I need an account or an API key?
Neither. The prompt is assembled by JavaScript in your own browser from the options you pick, so there is nothing to sign up for and nothing to connect.
Which image platforms is the output compatible with?
The output is plain descriptive English, so it can be pasted into any tool that accepts a text prompt. Platform-specific parameter syntax is not added — if your tool uses its own flags for aspect ratio or version, add those yourself after pasting.
What is a negative prompt and do I need one?
A negative prompt lists what you want kept out of the image, such as blur, distortion, watermarks or text artefacts. Tick the checkbox to generate one matched to your image type. Some platforms have a separate negative prompt field; if yours does not, you can ignore it.
Can I edit the generated prompt?
Yes. Both output boxes are editable, so you can rewrite, shorten or extend the text before copying. Trimming a prompt is often as useful as adding to it.
What does the Random Idea button do?
It drops one of more than thirty built-in starting ideas into the input box, covering portraits, architecture, nature, products, fashion, food, fantasy, sci-fi, animals, travel, vehicles and interiors. Use it as a starting point and edit it to suit your project.
Will the same prompt always give the same image?
No. Image models introduce randomness, and each platform interprets wording differently. A well-structured prompt improves consistency, but no prompt can guarantee a specific outcome.
Is anything I type stored?
No. The text never leaves your device — nothing is sent to a server, saved or logged by the generator. Refreshing the page clears it.
