Rewriting content in Bricks with ChatGPT for better SEO using Gato GraphQL for WordPress

We can use ChatGPT with the Bricks extension to automatically rewrite the content in Bricks page elements for better SEO, all with a single Gato GraphQL query.

This query uses ChatGPT to rewrite the content in the heading and text elements of a Bricks page, for better SEO.

We must provide the following variables:

customPostId: The ID of the Bricks custom post to update
openAIAPIKey: The API key for the OpenAI API

Here is the GraphQL query:

query InitializeGlobalVariables
  @configureWarningsOnExportingDuplicateVariable(enabled: false)
{
  emptyArray: _echo(value: [])
    @export(as: "elementToUpdateIDs")
    @export(as: "elementToUpdateTexts")
    @remove
}
 
query GetBricksData($customPostId: ID!)
  @depends(on: "InitializeGlobalVariables")
{
  customPost(by:{ id: $customPostId }, status: any) {
    id
    title
    bricksData(filterBy: { include: ["heading", "text"] })
      @underEachArrayItem(
        affectDirectivesUnderPos: [1, 3]
      )
        @underJSONObjectProperty(by: { key: "id" })
          @export(as: "elementToUpdateIDs")
        @underJSONObjectProperty(by: { path: "settings.text" })
          @export(as: "elementToUpdateTexts")
  }
}
 
query CreateDescriptionsWithChatGPT(
  $openAIAPIKey: String!
  $systemMessage: String! = "You are an SEO content writer"
  $promptTemplate: String! = """

      __typename
      ...on CustomPost {
        id

}

The variables would look like this:

{
  "customPostId": 123,
  "openAIAPIKey": "sk-..."
}
