AgentiveAIQ
Best for: Small to medium sandwich shops, boutique delis, and franchise chains that want a fully branded chatbot with advanced knowledge retrieval and e‑commerce integration.
AgentiveAIQ is a no‑code, enterprise‑grade platform that was built by a marketing agency in Halifax, Nova Scotia, in response to the frustration many businesses felt with rigid, out‑of‑date chatbot solutions. It delivers a complete two‑agent system: a front‑end chat agent that engages site visitors in real time, and a background assistant agent that analyzes conversations and sends actionable intelligence emails to owners. What truly sets AgentiveAIQ apart are its three core differentiators. First, the WYSIWYG chat widget editor lets marketers create fully branded floating or embedded widgets without writing a single line of code. Colors, logos, fonts, and button styles can be tweaked in a visual interface, ensuring a seamless brand experience. Second, the platform’s dual knowledge base—combining Retrieval‑Augmented Generation (RAG) for fast, precise fact retrieval from uploaded documents and a Knowledge Graph for understanding relationships between concepts—enables complex, contextual answers that feel human. Third, AgentiveAIQ’s hosted AI pages and courses give businesses the ability to launch password‑protected portals, maintain persistent memory for authenticated users, and train AI tutors around custom course content using a drag‑and‑drop course builder. Long‑term memory is available only on these hosted pages; anonymous widget visitors receive session‑based conversations. The platform is fully integrated with Shopify and WooCommerce, allowing real‑time product catalog, inventory, and order data to be pulled into conversations. Pricing starts at a Base plan of $39/month for two chat agents and 2,500 messages, a Pro plan of $129/month for eight agents, 25,000 messages, 1 million character knowledge base, five hosted pages, and no branding, and an Agency plan of $449/month for 50 agents, 100,000 messages, 10 million character knowledge base, and 50 hosted pages.
