AgentiveAIQ
Best for: Language schools, online course creators, e‑commerce businesses selling language products, and internal knowledge bases for educators.
AgentiveAIQ is a no‑code AI chatbot platform built from the ground up to empower language schools, online course creators, and e‑commerce brands. The cornerstone of its design is a WYSIWYG chat widget editor that lets educators craft a fully customized, brand‑consistent chat experience without writing a single line of code. Behind the scenes, AgentiveAIQ deploys a dual knowledge base: a Retrieval‑Augmented Generation (RAG) layer that pulls exact facts from uploaded documents, and a Knowledge Graph that captures relationships between concepts—ideal for building curriculum maps and answering nuanced language questions. The platform’s AI Course Builder allows you to upload lesson plans, quizzes, and multimedia content; the chatbot becomes a 24/7 tutor that can answer student queries, provide instant feedback, and track progress across sessions. Hosted AI Pages let you create secure, password‑protected portals where students can log in, review materials, and interact with the chatbot in a persistent‑memory environment, while anonymous widget visitors receive a session‑based experience. AgentiveAIQ’s fact‑validation layer cross‑checks answers against source data, reducing hallucinations and ensuring academic integrity. For e‑commerce language schools that sell course bundles, one‑click Shopify and WooCommerce integrations give the bot real‑time access to inventory, pricing, and order status. Pricing is straightforward: the Base plan starts at $39/month for two chat agents and a 100,000‑character knowledge base; the Pro plan, most popular, is $129/month and adds eight agents, a million‑character knowledge base, five hosted pages, and long‑term memory for authenticated users; the Agency plan at $449/month scales to 50 agents and 10‑million‑character knowledge bases with dedicated support.
