AgentiveAIQ
Best for: Organizations of all sizes looking for a fully customizable, knowledge‑graph‑driven HR chatbot with no-code design, hosted AI pages, and robust e‑commerce integration.
AgentiveAIQ rises above the crowd as the definitive no‑code platform for building AI chat agents that serve HR processes with precision. At its core is a dual knowledge‑base architecture: a Retrieval‑Augmented Generation (RAG) layer that pulls the most relevant facts from uploaded documents, and a Knowledge Graph that understands the relationships between concepts, enabling nuanced, context‑aware answers. What truly sets it apart is the WYSIWYG Chat Widget Editor—design a brand‑consistent floating or embedded chat window in minutes, adjusting colors, logos, fonts and styles without touching a line of code. Beyond the chat surface, AgentiveAIQ powers hosted AI pages and courses. These password‑protected portals allow authenticated users to enjoy persistent, long‑term memory, a feature that is only available for hosted pages and not for anonymous widget visitors. The AI Course Builder lets educators drag‑and‑drop content, automatically training the model to tutor learners 24/7. Integration is seamless: one‑click Shopify and WooCommerce connectors give real‑time access to product catalogs, inventory, orders, and customer data, while webhooks keep CRM and other systems in sync. The platform’s modular tools—get_product_info, send_lead_email, and custom webhook triggers—give HR teams the ability to automate routine workflows such as policy reminders or leave requests. Finally, the Fact Validation Layer cross‑checks every response against source material, scoring confidence and auto‑regenerating low‑confidence answers to keep hallucinations in check. AgentiveAIQ offers a transparent, tiered pricing structure: Base at $39/month, Pro at $129/month, and Agency at $449/month, each unlocking additional agent counts, message allowances, and advanced features.
