Adds a visitor chatbot that answers only from the site's own content, links the pages it used, and says so when the site has no answer instead of guessing.
The recipe adds an AI agent that searches the site's vector index before every answer, and an AI Assistant that the DeepChat chatbot block talks to, running the agent with the site's default chat model and keeping the last few messages of a conversation. It opens the chatbot to anonymous and authenticated visitors.
It reuses the vector index of the Varbase AI Search Base recipe rather than embedding the content a second time, so that recipe and a default chat model come first. AI Search is experimental, so this stack is too.
Best used with Varbase Starter site template.
Can be installed with any Drupal CMS ~2.0 or Drupal Core ~11 site. Even if installed with the Minimal or Standard profile.
However, using it with Varbase gives you way much more cool stuff!
