Common quality issues
What Is a Negative Prompt Generator?
A negative prompt tells an AI image tool what to avoid, blurry results, extra fingers, watermarks, rather than what to include. Many AI image generators, including Stable Diffusion and Midjourney, accept a separate negative prompt field, and using one consistently improves output quality by ruling out common failure modes upfront.
The tool above is free, runs entirely in your browser, and doesn’t send your input anywhere.
How to Use This Free Negative Prompt Generator
- Check the quality issues you want to avoid, a sensible default set is pre-checked.
- Add any of your own in the text field if there’s something specific you keep seeing.
- Click “Generate Negative Prompt,” then paste it into your image tool’s negative prompt field.
Where to Use a Negative Prompt
In Stable Diffusion-based tools, there’s usually a dedicated negative prompt field separate from the main
prompt. In Midjourney, use the --no parameter followed by the terms, for example
--no watermark, text. Check your specific tool’s documentation for the exact syntax it expects.
Frequently Asked Questions
Is this negative prompt generator free to use?
Yes. It’s completely free, has no sign-up, and runs in your browser.
Does every AI image tool support negative prompts?
Most do, but the exact field or syntax varies, some use a separate field, others use a parameter like --no.
Should I check every box?
No, checking every option can over-constrain the generation. Start with the pre-checked defaults and add specific ones only if you keep seeing that issue.
Can I use this alongside a regular prompt?
Yes, pair it with our Image Prompt Generator or Midjourney Prompt Generator for the main description.
