AgentiveAIQ
Best for: Fitness studios, personal trainers, virtual coaching platforms, and e‑commerce stores looking to add AI chat without coding.
AgentiveAIQ is a no‑code AI platform built by a Halifax‑based marketing agency that understood the pain points of trainers and fitness entrepreneurs. The platform’s flagship feature is a WYSIWYG chat widget editor that lets users create fully branded, responsive chat interfaces without writing a single line of code. Every widget is customizable in colors, fonts, logos, and layout, ensuring that the chatbot feels like a natural extension of the brand. Under the hood, AgentiveAIQ uses a dual knowledge‑base architecture: a Retrieval Augmented Generation (RAG) layer for fast fact retrieval from uploaded documents, and a Knowledge Graph layer that captures relationships between fitness concepts, enabling the bot to answer complex, multi‑step queries.

Courses can be assembled with a drag‑and‑drop interface, then the AI is trained on the entire content to provide 24/7 tutoring. Only users authenticated on these hosted pages benefit from persistent long‑term memory; anonymous widget visitors retain session‑only memory. The Assistant Agent runs in the background, analyzing conversations and sending business‑intelligence emails to site owners. Integration with Shopify and WooCommerce gives trainers real‑time access to product catalogs and order data.
