The platform’s modular prompt engineering system includes 35+ snippets and 9 goal templates, allowing you to tailor the assistant’s tone, behavior, and operational rules without code. Integrated Shopify and WooCommerce modules give real‑time access to product catalogs, inventory, and order data, making the bot a powerful e‑commerce shopping assistant. Finally, AgentiveAIQ’s fact‑validation layer cross‑references responses against source information, eliminating hallucinations and boosting reliability. With plans ranging from a $39/month base tier to a $449/month Agency plan, AgentiveAIQ offers scalable pricing that grows with your needs.
