Negative Prompt Builder
100% PrivateAI & Prompt ToolsBuild the negative prompt that tells an image model exactly what to leave out of the picture.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
Tick the terms you want to exclude, or add your own. Support for negative prompts varies by image generator: some take a separate negative field, others need the terms inside the main prompt, and a few ignore them entirely.
Tick at least one preset term or type a custom term, and the negative prompt will appear here.
- 1Work through the four groups and tick every term that applies to your image.
- 2Add custom terms in the box, separated by commas or lines.
- 3Read the assembled negative prompt at the bottom.
- 4Copy it into your image generator's negative prompt field or prompt, as that tool requires.
Ticked: "blurry" and "low-resolution" from Photo quality defects, and "deformed hands" from Anatomy and people. No custom terms. Result: "blurry, low-resolution, deformed hands"
- Support varies by generator: Stable Diffusion tools have a dedicated negative field, some services accept terms inside the main prompt, and a few ignore negatives entirely. The builder cannot change that.
- More terms is not always better: excluding a style term like "painting" only makes sense when you want a photograph.
- The preset lists are curated static text on this page; nothing is generated or fetched.
A list of unwanted qualities the image model should steer away from during generation, the counterpart to the main prompt that describes what you do want.
About this tool
The Negative Prompt Builder assembles the list of things you do NOT want in an AI-generated image: quality defects like blur and noise, anatomy problems like extra fingers, text and watermark artifacts, and unwanted styles like cartoon or CGI. Tick terms from the curated checklists, add your own, and the tool produces one clean comma-separated negative prompt with duplicates removed.
