HomeCasa What are variables in a prompt
Variables turn a prompt into a reusable template. Learn how to define them, name them and use them on HomeCasa Prompts.
A variable is a slot inside a prompt that gets a different value each time you use it. Thanks to variables, the same prompt works for hundreds of similar situations.
Example
Write an 80-word product description for {{product}},
aimed at {{audience}}, with a {{tone}} tone.If you replace {{product}} with “a reading lamp”, {{audience}} with “students” and {{tone}} with “youthful”, you get a complete prompt without rewriting anything.
How they work on HomeCasa Prompts
In our library, variables are written between double curly braces: {{variable_name}}. On each prompt page:
- Click Customize to see the field for each variable.
- Type your values: the prompt updates instantly.
- Click Copy prompt and paste it into your AI tool.
- Use Reset values to go back to the defaults.
The values you type stay in your browser; they are not sent to our servers.
Best practices
- Clear names:
{{target_audience}}beats{{x}}. - Example values: a good default shows what kind of information is expected.
- Only what changes: if something is the same in every use, write it directly in the prompt.
- Closed lists when it makes sense: tone (formal, friendly…), platform (TikTok, Reels…).
Variables in your own prompts
You can use the same idea in any tool: write your prompt with slots marked as [PRODUCT] or {{product}} and save it in your notes. Before using it, replace the slots. Some tools and automation platforms can fill in variables automatically.
