This... looks like a keyword-lookup table with a web-search-and-polish fallback? The README claims "Multi-turn context" and "Conversation memory," but the client sends exactly one thing per request (to a Google Apps Script of all things), which is the question. No session, no history, no context. There is no conversation to remember. This is "AI" in the same way a graphing calculator is "Wolfram Alpha".
My favorite part might be the comments in the stylesheets. "PREMIUM GLASS CONDUIT CONTAINER", "CHATBOX PERFORMANCE ENGINE", "ULTRA-CLEAN GLASS CONTEXT MENU".
