# Prompts

### Prompts

When utilized properly, **Artificial Intelligence** (**AI**) can enhance your app with sophistication and intelligence. The app runtime supports a growing suite of AI features. One such feature is the ability to turn any app object into a real time AI prompt.

Follow these steps to turn **any** object type into an AI **prompt**:

1. Add the special **prompt_** prefix to the object's name. This will instruct the runtime to treat the object as an AI prompt.
2. Update the output language of your object to include a required **user prompt** and optional **system prompt**. **User** prompts provide instructions to the AI, while **system** prompts define its role. When both prompts are provided, the system prompt must appear first and be terminated with the special '**~**' character. These prompts can reference other app objects using the normal **object token syntax**.

### How it Works

When a **prompt object** is rendered, any other referenced app object outputs, along with the provided prompt(s) will be sent as **input** to a real time **chat session**. The results of the chat session will then be inserted as the final **output** of the prompt object.

Since this feature works universally for all object types, currently there is not a designed **Prompt** object type. This may change in the future.

### Remarks

**Sentence** objects are a great building block for creating AI prompts.

### Examples

Below is the output language for a **Sentence** object, named **prompt_bmi** used as an AI prompt. Notice how the person's age, gender, weight, and height are dynamically collected from other app objects using normal **object token syntax**. We include both system and user prompts. Note the required '**~**' token at the end of the system prompt.

```
You are an expert in healthcare and mathematics.~
Calculate the BMI for a [1] year old [2] who weighs [3] lbs and is [4] inches tall.
Simply state 'BMI = {bmi}. {improve}.'
Where {bmi} is the calculated BMI.
Where {improve} is a one sentence description for how the person can improve their BMI. This sentence should be in second person.

Output:
BMI = 28.32. You can improve your BMI by incorporating regular exercise and a balanced diet to achieve a healthier weight.
```

Here is a similar example, but this time without a system prompt:

```
Calculate the BMI for a [1] year old [2] who weighs [3] lbs and is [4] inches tall.
Simply state 'BMI = {bmi}' where {bmi} is the calculated BMI.
Do not provide any other explanation.

Output:
BMI = 28.32
```
