Chat

Use a Chat component to allow users to leave comments for each other or chat directly with ChatGPT powered by the OpenAI integration

Power the Chat component with ChatGPT

info

To create a Chat component that streams messages in real time, follow the guide here.

1. Set up the OpenAI integration
2. Add a Chat component to the canvas
3. Create a new backend API with an OpenAI step
   • Set Action to "Generate ChatGPT Response"
   • Set Prompt to {{Chat1.userMessageText}}
   • Set Message History to {{Chat1.messageHistory}}
4. Set the Message History Data field in the Chat component to {{API1.response.messageHistory}}
5. Add an event handler onMessageSend to run the API

Now, when you type in the Chat component, you can interact directly with ChatGPT in your Superblocks application.
