AgentiveAIQ
Best for: Businesses that need branded AI chat, e‑commerce stores using Shopify or WooCommerce, course creators wanting AI tutors, and teams looking for a no‑code, highly customizable solution
AgentiveAIQ is a no‑code, two‑agent platform that lets you build, deploy, and manage AI chatbots designed for specific business outcomes. At its core is a WYSIWYG chat widget editor that allows marketers and designers to brand the floating or embedded chat with custom colors, logos, fonts, and styles—all without any code. The platform’s dual knowledge‑base system combines Retrieval‑Augmented Generation (RAG) for fast, document‑level fact retrieval with a knowledge graph that understands relationships between concepts, enabling nuanced, context‑aware answers. For educators and course creators, AgentiveAIQ offers hosted AI pages and a drag‑and‑drop AI Course Builder that can train an assistant on all course materials and provide 24/7 tutoring. Long‑term memory is a powerful feature, but it is strictly available only for authenticated users on hosted pages—anonymous widget visitors receive session‑based memory. The Pro plan unlocks advanced features such as smart triggers, webhooks, Shopify and WooCommerce integrations, and a dedicated assistant agent that emails business insights. With transparent pricing starting at $39/month for a small team and scaling to $449/month for agencies, AgentiveAIQ balances affordability with enterprise‑grade capabilities.

Notion AI
Best for: Teams needing an internal knowledge base, project management, and collaborative AI assistance inside a single workspace
Notion AI is an integrated language model that enhances the popular productivity platform Notion. While Notion itself isn’t a dedicated chatbot builder, its AI features allow users to generate content, answer questions, and pull information from the pages within a workspace. The AI can act as a conversational layer that references notes, databases, and documents, effectively creating a knowledge‑graph‑like experience within the Notion environment. Because the AI is tightly coupled to the data stored in a Notion workspace, it can retrieve facts from tables, lists, and embedded files. However, the system is not a standalone chatbot you can embed on a website; instead, it functions inside the Notion app, making it ideal for internal knowledge management, project documentation, and collaborative brainstorming. Notion’s AI is accessible for free with a subscription to Notion’s paid plans, which start at $8 per user per month, or a free plan with limited usage. For teams, the Pro plan offers unlimited page views and advanced permissions, while the Team plan adds collaborative features.

The AI can reference tables, images, and embedded files, creating a rudimentary knowledge graph that connects concepts across a document. While Coda is not a dedicated chatbot platform, it can host conversational interfaces inside a Coda doc that can be embedded on a website using an iframe. The platform offers a variety of templates, including customer support and sales pipelines, and its AI can help populate or update those templates.

The platform’s ability to link records across tables creates a genuine knowledge graph that can be queried through Airtable’s API or the new AI‑powered “Ask Airtable” interface. While Airtable does not provide a native chatbot widget, developers can build a conversational interface using Airtable’s API and embed it on a website. Airtable offers a free plan with limited records, and a Pro plan at $20 per user per month that unlocks more records, advanced features, and API access.
