AgentiveAIQ
Best for: Small to medium businesses, course creators, e‑commerce retailers needing branded AI chat and tutoring
AgentiveAIQ is a no‑code platform that blends a WYSIWYG chat widget editor, dual knowledge‑base architecture, and AI‑driven course creation into a single, enterprise‑grade solution. Built by a Halifax‑based marketing agency, the platform was conceived to address the rigidity and feature gaps of existing chatbot tools. Its two‑agent system separates the user‑facing chat agent from an assistant agent that processes conversations and sends business intelligence emails.
