How to Use This Prompt Weight Syntax Formatter
How to Use the Prompt Weight Syntax Formatter
Transform your text into properly weighted AI prompts with these simple steps:
- Enter Your Text: Paste or type your prompt text in the input area. Each word will be analyzed and formatted according to your settings.
- Choose Weight Format: Select the appropriate syntax for your AI model:
- Parentheses (word:weight) for Stable Diffusion and ComfyUI
- Double colon word::weight for Midjourney
- Square brackets [word:weight] for specialized models
- Set Weight Value: Choose emphasis strength from 0.1 to 3.0. Start with 1.2 for moderate emphasis, 1.5 for stronger effects.
- Configure Targeting: Decide which words to format - all words, only nouns/adjectives, or custom selection with exclusion lists.
- Generate Result: Click 'Format Prompt' to instantly transform your text with proper weight syntax ready for AI models.
The tool automatically handles punctuation preservation and provides formatted output you can copy directly into your AI interface.
How It Works
How the Prompt Weight Formatter Works
Our weight formatter uses sophisticated text parsing to apply emphasis syntax correctly:
- Text Analysis: The tool parses your input text, identifying individual words, phrases, and punctuation marks for proper formatting.
- Smart Word Selection: Based on your target mode, it filters words using built-in dictionaries to skip common connectors or apply custom exclusion lists.
- Syntax Application: Each selected word is wrapped with the chosen format (parentheses, colons, brackets) using your specified weight value.
- Punctuation Preservation: Commas, periods, and other punctuation are intelligently preserved outside the weight formatting to maintain readability.
- Format Validation: The output is validated for proper syntax formatting to ensure compatibility with your target AI model.
The formatter supports multiple AI model conventions and provides consistent, clean output optimized for prompt engineering workflows.

Frequently Asked Questions
What's the difference between (word:1.2) and word::2 formats?
The parentheses format (word:1.2) uses decimal weights and is standard for Stable Diffusion and ComfyUI models. The double colon format (word::2) uses integer multipliers and is preferred by Midjourney. Both control emphasis but with different scaling - parentheses typically range 0.5-1.5 while colon format uses 0.25-2.0 multipliers.
What weight values should I use for different AI models?
For Stable Diffusion, use 0.8-1.3 for subtle adjustments and 0.5-1.5 for stronger effects. Midjourney works well with ::0.5, ::2, or ::3 multipliers. Values above 2.0 can cause over-emphasis artifacts, while below 0.3 may completely suppress concepts. Start with moderate weights (1.1-1.3) and adjust based on results.
Should I weight every word in my prompt?
No, selective weighting is more effective than weighting every word. Focus on key concepts, styles, and important details while leaving connecting words unweighted. Over-weighting can create unnatural results and conflicts between competing emphasized elements. Use the 'Nouns & Adjectives' mode to automatically skip common connector words.
Can I use negative weights to reduce unwanted elements?
Yes, negative weights (like (unwanted:0.7) or [bad:0.5]) can reduce emphasis on undesired concepts. However, negative prompts (separate negative prompt field) are usually more effective for completely avoiding unwanted elements. Use negative weights for fine-tuning rather than complete removal, as they still include the concept with reduced influence.
How do weighted prompts affect generation consistency?
Consistent weight formatting improves repeatability across generations. Random or excessive weighting can increase output variance. Use systematic weight values (like 1.1, 1.2, 1.3) rather than random decimals. Document your weight schemes for complex prompts to maintain consistency when iterating or sharing prompts with others.
