AI Chatbot Widget

Builder can embed an AI-powered chat widget directly into the website it generates for you — a chatbot for your site's own visitors, separate from the chat you use to build the site.

Configure it from the LLM tab of a project's Admin Panel.

Setup

  • Enable or disable the widget for your site.
  • Choose a model — the chatbot runs on Claude, and you can pick the tier (Haiku, Sonnet, or Opus) that best balances response quality and cost for your use case.
  • Write a system prompt describing how the chatbot should behave, or have Builder suggest one based on your site's actual content.
  • Set a welcome message shown when a visitor opens the chat.
  • Provide the API key the chatbot will use. It's stored securely rather than in plain text.

Testing before you publish

Before your visitors see it, you can:

  • Test the connection to confirm your API key is valid.
  • Test the prompt to see how the chatbot responds with your current configuration.

Publishing

The chatbot goes live on your site once you publish/deploy the project with the widget enabled.
