Stable Diffusion is a powerful AI image generation tool that creates images from text prompts. To generate high-quality images, it is important to write effective prompts. A good prompt should clearly describe the desired image while avoiding ambiguity.
Prompt checkers analyze prompts to provide feedback on how to improve them. This allows users to iterate and refine prompts before generating images. In this article, we will discuss prompt checkers for Stable Diffusion and provide examples of effective prompts.
What Makes a Good Prompt?
An effective Stable Diffusion prompt should:
- Be specific in describing the subject, style, composition, etc.
- Use adjectives and descriptive language
- Include relevant stylistic and compositional keywords
- Avoid subjective or ambiguous words like “beautiful” or “perfect”
Including too many elements in a prompt can result in a cluttered final image. The best prompts strike a balance between providing enough detail while still allowing some creative freedom.
PromptHero
PromptHero is a site dedicated to curating and sharing top Stable Diffusion prompts. Users can browse prompts by category and view highly-rated prompts submitted by others.
Some example top-rated prompts from PromptHero:
