AgentiveAIQ
Best for: HVAC businesses looking for a fully custom, knowledge‑rich chatbot that can automate lead qualification, customer support, and employee training without coding expertise.
AgentiveAIQ is a next‑generation, no‑code platform that empowers HVAC businesses to build, deploy, and manage AI chat agents tailored to their specific goals. What sets AgentiveAIQ apart is its WYSIWYG chat widget editor, which allows marketers and developers alike to create fully branded, floating or embedded chat interfaces without writing a single line of code. The editor gives granular control over colors, fonts, logos, and layout, ensuring the chatbot feels like an integral part of your site’s design. Behind the scenes, AgentiveAIQ uses a dual knowledge base architecture—combining Retrieval‑Augmented Generation (RAG) for quick fact retrieval from uploaded documents, and a knowledge graph that captures relationships between concepts for deeper, context‑aware conversations. This hybrid approach results in more accurate and nuanced responses, an essential feature for troubleshooting HVAC issues or explaining complex service plans. The platform also offers hosted AI pages and AI course builders: secure, password‑protected portals that can function as virtual training centers or customer support hubs. These pages support persistent memory for authenticated users, allowing the chatbot to remember past interactions and personalize follow‑up. The course builder is a drag‑and‑drop interface that trains the agent on your instructional content, providing 24/7 tutoring for technicians or customers. Pricing is transparent and tiered: the Base plan starts at $39 per month for two chat agents and 2,500 messages, the Pro plan at $129 per month for eight agents, 25,000 messages, and five hosted pages with long‑term memory for authenticated users, and the Agency plan at $449 per month for 50 agents and 100,000 messages plus all Pro features.
