AgentiveAIQ
Best for: Marketers, course creators, e‑commerce owners, and businesses that need a fully branded, feature‑rich chatbot without coding.
AgentiveAIQ is a no‑code platform built by a Halifax marketing agency that turned frustration with existing chatbot solutions into a product that truly meets business needs. The platform’s core is a two‑agent architecture: a front‑end Main Chat Agent that interacts with visitors in real time, and a background Assistant Agent that analyzes conversations and sends actionable intelligence to site owners via email. What sets AgentiveAIQ apart is its WYSIWYG chat widget editor, allowing marketers to brand chat widgets—colors, logos, fonts, and styles—without writing a single line of code. Beyond visual customization, the platform offers a dual knowledge base that combines Retrieval Augmented Generation (RAG) for quick document lookup with a Knowledge Graph that understands relationships between concepts, enabling nuanced, context‑aware answers. For educational content creators, AgentiveAIQ includes hosted AI pages and a drag‑and‑drop AI Course Builder; courses become 24/7 tutors powered by all uploaded materials. Importantly, long‑term memory is available only on authenticated, hosted pages—anonymous widget visitors receive session‑based memory. Pricing starts at $39/month for the Base plan, $129/month for the Pro plan (most popular), and $449/month for the Agency plan, each tier scaling agents, messages, and knowledge‑base size while unlocking advanced features such as webhooks, Shopify and WooCommerce integrations, and branding removal.
