# Generate ChatGPT Message

## Overview

This rule runs after a location and time is collected on `Step 1` and the step is submitted. The field entries are used to query ChatGPT to generate a customized invite message that is editable in a [text area](/platform/build-forms/elements/fields/text-area.md) field on `Step 2`.

This pattern can be used to integrate with any AI service to generate any content from any user inputs.

## Rule Logic

```
const location = AILocation.value;
const time = AITime.value;
const eventType = AIEventType.value;

const res = await feathery.http.POST('https://api.openai.com/v1/chat/completions', {
    "model": "gpt-3.5-turbo",
    "messages": [
      {
        "role": "system",
        "content": "You are a friendly event planner. Maximum 50 word responses."
      },
      {
        "role": "user",
        "content": `Create an invitation message for an event. The location is ${location}. The time is ${time}. The event type is ${eventType}.`
      }
    ]
})

AIMessage.value = res.choices[0].message.content;
```
