About the Negative Prompt Generator
A negative prompt tells an image generator what to avoid, rather than what to include — it's how you filter out common defects like deformed hands, extra fingers, blurry or garbled text, watermarks, and general low-quality artifacts. This tool organizes commonly used negative prompt terms into six defect categories you can toggle on or off, plus a field for adding your own terms specific to your image. Hands & Anatomy and Text & Watermarks are enabled by default, since deformed hands and garbled text are two of the most common AI image generation problems. Everything runs locally in your browser — the generated list is just text for you to paste into your own image generation tool.
Flux Note
Stable DiffusionNegative prompts are a native, core feature — the model was built around classifier-free guidance (CFG), which is exactly the mechanism negative prompts rely on. This works reliably across essentially all Stable Diffusion versions and interfaces.
Flux (standard/dev variants)Flux wasn't originally designed around the same CFG mechanism. Some interfaces and community workarounds do support negative prompts to a meaningful degree, but support and effectiveness vary by tool.
Flux Schnell & other distilled/fast variantsFast, few-step models are typically distilled specifically to skip classifier-free guidance for speed. Forcing negative-prompt-style guidance on these can produce degraded results rather than the intended filtering effect.
Practical takeawayIf you're using Flux and negative prompts don't seem to be doing anything, that may be an architectural limitation of your specific variant, not a mistake in your wording — check what your particular interface documents about negative prompt support.
