Using Variables in Your Prompts

Smart Variables transform static prompts into flexible templates that adapt to any situation.

What Are Prompt Variables?

Think of variables as placeholders in your prompts. Instead of hardcoding specific values, you mark certain parts as variables and fill them in each time you use the prompt. This makes your prompts incredibly versatile.

Many prompts are reused with small tweaks. You might change the product name, audience, domain, or scenario. Smart Variables let you keep one template and fill in small differences every time you use it.

A Simple Example

Without Variables (Static):

Write a professional email about the Q4 product launch for our enterprise customers.

With Variables (Flexible):

Write a [tone] email about [topic] for [audience].

The second version can be used for any tone (professional, casual, friendly), any topic (product launch, meeting invitation, follow-up), and any audience (enterprise customers, team members, partners).

Creating Your First Variable

In Prompt Bravo, creating variables is simple. Just wrap any text with square brackets:

Variable Syntax: [variable_name]

When you use the prompt, Prompt Bravo will automatically detect the variables and prompt you to fill them in. Once you enter the values, click copy and paste into your AI tool.

How to Create a Variable-Enabled Prompt

  1. Create a new prompt or edit an existing one.
  2. Wrap the changing parts with square brackets, for example [productName], [audience], [domain], [scenario].
  3. Save the prompt. Prompt Bravo now knows which parts should be filled each time. Here is an example template:

Generate a landing page outline for [productName] targeting [audience] in the [domain] space. Focus on [scenario] and include three key benefits.

Using Your Template in Seconds

  1. Select the prompt that contains variables.
  2. Prompt Bravo will show input fields for each variable.
  3. Type your values and confirm. The prompt is generated with your inputs.
  4. Copy in one click and paste into ChatGPT or Claude to run your command.

Common Variables to Start With

  1. productName for different products or features
  2. audience for roles such as marketers, developers, or executives
  3. domain for industry or topic such as fintech or education
  4. scenario for the situation such as onboarding, launch, or renewal
  5. tone for professional, casual, friendly, or formal voice
  6. length for short, medium, or detailed output

Benefits of Using Variables

  1. Reusability: One template covers many cases
  2. Speed: Fill values once and move on
  3. Consistency: Keep structure and tone the same across tasks
  4. Fewer errors: Avoid old names or details sticking around
  5. Less clutter: Replace 10 similar prompts with one flexible template

Best Practices for Variables

Do:

  1. Use descriptive variable names
  2. Keep variables focused and specific
  3. Test with different values
  4. Limit to 3-5 variables per prompt

Don't:

  1. Use too many variables (more than 7)
  2. Make variables too vague
  3. Use single letters like [x] or [a]
  4. Make everything a variable
