Variable

The Variable block creates dynamic placeholders in your prompts that can be filled in with different values each time. Variables make your prompts reusable and customizable, turning a single prompt template into a flexible tool that adapts to different inputs.

When to Use

Use Variable blocks when:

• Reusable templates: Same prompt structure, different inputs each time
• User inputs: Names, topics, or preferences that change
• Dynamic content: Data that comes from external sources
• A/B testing: Comparing prompt variations with controlled changes
• Parameterized workflows: Building prompt libraries for teams

How to Use

1. Add a Variable block to your prompt canvas
2. Define your variable with a clear, descriptive name
3. Use the syntax {{variable_name}} in other blocks where the value should appear
4. Provide default values or descriptions for clarity
5. Fill in values before running the prompt

Syntax

Variables use double curly braces:

{{variable_name}}

Examples:

• {{user_name}} - A person's name
• {{product_description}} - Longer text content
• {{programming_language}} - A specific option
• {{max_words}} - A numeric value

Examples

Customer Support Template

Variables defined:

{{customer_name}} - The customer's first name
{{issue_type}} - bug, feature request, or billing
{{product}} - The product they're asking about

Used in prompt:

Write a friendly support response to {{customer_name}} regarding
their {{issue_type}} with {{product}}. Acknowledge their concern
and provide next steps.

Code Generation Template

Variables defined:

{{function_name}} - Name for the new function
{{input_type}} - TypeScript type for the input
{{output_type}} - TypeScript type for the return value
{{description}} - What the function should do

Used in prompt:

Create a TypeScript function called {{function_name}} that:
- Accepts a parameter of type {{input_type}}
- Returns {{output_type}}
- Purpose: {{description}}

Include JSDoc comments and handle edge cases.

Content Localization Template

Variables defined:

{{original_text}} - The content to adapt
{{target_market}} - The market/region (e.g., "UK", "Australia")
{{tone}} - formal, casual, or playful

Used in prompt:

Adapt the following content for the {{target_market}} market:

{{original_text}}

Adjust spelling, idioms, and cultural references appropriately.
Maintain a {{tone}} tone throughout.

Tips

• Use descriptive names: {{user_query}} is clearer than {{q}} or {{input}}
• Include expected format: Note if a variable should be a number, list, or specific format
• Provide examples in descriptions: "e.g., 'JavaScript', 'Python', 'Rust'"
• Set sensible defaults: Good defaults make templates immediately usable
• Group related variables: Keep variables for the same concept together
• Validate inputs: Consider what happens with empty, very long, or unusual values
• Document your variables: Future you (or your team) will thank you
