AgentiveAIQ
Best for: HVAC service providers of all sizes that need a fully branded, knowledge‑rich chatbot with learning capabilities and e‑commerce integration.
AgentiveAIQ is a no-code, enterprise‑grade chatbot platform that empowers HVAC companies to capture, qualify, and convert leads directly from their website. Built by a Halifax marketing agency, it was created to solve the pain points of rigid, feature‑poor chatbot tools. Its WYSIWYG chat widget editor lets you design fully branded floating or embedded chat windows without writing a single line of code—colors, fonts, logos, and layouts can be tweaked visually. The dual knowledge base system combines Retrieval Augmented Generation (RAG) for precise document‑level answers with a Knowledge Graph that understands relationships between concepts, enabling nuanced conversations about HVAC products, troubleshooting, and maintenance schedules. For companies offering training or certification, AgentiveAIQ’s AI Course Builder allows the creation of interactive, password‑protected learning paths that remember user progress on authenticated hosted pages, using long‑term memory only for those logged‑in visitors. The platform also supports one‑click Shopify and WooCommerce integrations, so product catalogs and inventory data can power real‑time recommendations. A dedicated Assistant Agent runs in the background, analyzing live chats and sending contextual business‑intelligence emails to site owners. Pricing starts at just $39/month for the Base plan, $129/month for the most popular Pro plan (which removes branding and unlocks long‑term memory, webhooks, and AI courses), and $449/month for the Agency plan with 50 agents and 10M character knowledge base.
