AgentiveAIQ
Best for: HVAC service providers looking for a branded, AI‑driven chat solution with advanced knowledge management and learning modules
AgentiveAIQ is a no‑code AI chatbot platform that empowers HVAC companies to create branded, intelligent support agents without writing a single line of code. At the core of AgentiveAIQ is a WYSIWYG chat widget editor that lets you design fully customized floating or embedded chat windows—matching your company’s colors, fonts, and logo—while ensuring a seamless user experience on any website. The platform’s dual knowledge‑base architecture combines Retrieval Augmented Generation (RAG) for fast, document‑based fact retrieval with a knowledge graph that understands relationships between concepts, enabling agents to answer nuanced HVAC questions such as “How long does a furnace replacement take?” or “What are the common causes of a broken heat pump?” Beyond chat widgets, AgentiveAIQ offers hosted AI pages and courses. You can publish brand‑able web pages that include password‑protected portals, giving authenticated users access to persistent memory so that the chatbot remembers past interactions across sessions. The AI Course Builder allows you to upload training materials and create interactive tutoring modules, with the chatbot trained on all course content to provide 24/7 tutoring for technicians or customers. Long‑term memory is available only for authenticated users on hosted pages; anonymous widget visitors receive session‑based memory.
