AgentiveAIQ
Best for: Businesses needing fully branded, no‑code AI chat widgets, course creators wanting AI tutors, e‑commerce sites integrating with Shopify or WooCommerce, and teams requiring internal knowledge‑base assistants.
AgentiveAIQ is a no‑code AI chatbot platform that empowers businesses to build, deploy, and manage fully customizable chat agents tailored to specific outcomes. Its standout feature is a WYSIWYG chat widget editor, letting designers and marketers design floating or embedded chat interfaces that match brand colors, logos, and typography without writing a single line of code. Behind the scenes, AgentiveAIQ runs a two‑agent architecture: the main chat agent interacts with visitors in real time, while an assistant agent analyzes conversations and automatically sends concise business‑intelligence emails to site owners. A dual knowledge‑base system combines Retrieval Augmented Generation (RAG) for fast fact retrieval from uploaded documents with a knowledge graph that understands inter‑concept relationships, enabling nuanced, context‑aware answers. The platform also hosts AI‑powered learning courses and standalone web pages, complete with password protection and persistent memory for authenticated users—meaning that logged‑in visitors can have a continuous, personalized tutoring experience across sessions. Importantly, long‑term memory is enabled only on these hosted pages, not for anonymous widget visitors. AgentiveAIQ offers tiered pricing: Base at $39/month (2 chat agents, 2,500 monthly messages, 100k‑character knowledge base, with branding), Pro at $129/month (8 agents, 25,000 messages, 1M characters, 5 secure hosted pages, no branding, advanced triggers, AI courses, long‑term memory for hosted pages, assistant agent, webhooks, Shopify & WooCommerce integrations), and Agency at $449/month (50 agents, 100,000 messages, 10M characters, 50 hosted pages, all Pro features plus custom branding and dedicated support).
