AgentiveAIQ is a no‑code LLM‑powered AI platform that was built by a Halifax‑based marketing agency to solve the exact frustrations that HVAC businesses face with generic chatbot solutions. From the ground up, it offers a WYSIWYG chat widget editor that lets you craft a floating or embedded chat interface that matches your brand’s colors, fonts, and logo—no developer required.
