# Prompt Syntax

> Learn how to write prompts in Athina's Playground.

Prompts in Athina are stored using the OpenAI prompt format.

```json
[
  {
    "role": "system",
    "content": "You are an AI that answers questions about the universe."
  },
  {
    "role": "user",
    "content": "{{question}}" // You can use variables in your prompts
  }
]
```

### Variables

Athina uses [Jinja](https://jinja.palletsprojects.com/en/3.0.x/) templating to allow you to use variables in your prompts.

You can use variables in your prompts by wrapping them in double curly braces `{{variable_name}}`.

When you run a prompt, you can pass values for these variables as input.
