Whether you’re building a product recommendation engine for an e‑commerce client or creating a knowledge‑base assistant for a B2B SaaS brand, the right RAG platform can unlock new revenue streams and elevate customer experience. Below you’ll find a side‑by‑side comparison of the top five RAG chatbots, complete with pricing, key features, pros and cons, and real‑world use cases—so you can choose the one that best aligns with your agency’s workflow and budget.
AgentiveAIQ
Best for: Marketing agencies, e‑commerce brands, course creators, internal knowledge bases, real‑estate and financial advisors needing custom, branded chat solutions
AgentiveAIQ is a no‑code, enterprise‑grade RAG chatbot platform that empowers marketing agencies to build, deploy, and manage AI agents tailored to specific business outcomes. From the moment you sign up, the platform gives you a WYSIWYG chat widget editor that lets you match your brand’s colors, fonts, and logo without writing a single line of code. Whether you need a floating chatbot on a client’s landing page or an embedded chat box within a custom form, the visual editor lets you tweak every style element in real time. The heart of AgentiveAIQ is its dual knowledge‑base architecture. It combines a Retrieval‑Augmented Generation (RAG) engine that pulls precise facts from documents and a Knowledge Graph that understands relationships between concepts, enabling nuanced, context‑aware conversations. For agencies that need to keep their chatbots up to date, you can upload PDFs, product catalogs, and internal SOPs, and the system will automatically index and surface the most relevant information. Beyond the core chatbot, AgentiveAIQ offers hosted AI pages and courses. These are fully branded, password‑protected portals that can serve as virtual training centers or knowledge bases for clients. When a user logs in, the platform activates long‑term memory, allowing the chatbot to remember past interactions within that session and across visits—this feature is exclusive to authenticated users on hosted pages, not anonymous widget visitors. The AI Course Builder lets you create interactive, drag‑and‑drop courses that the chatbot can tutor 24/7. The same underlying AI is trained on the course content, ensuring that students receive accurate, up‑to‑date answers. For e‑commerce clients, one‑click Shopify and WooCommerce integrations pull real‑time inventory, pricing, and order data, enabling the chatbot to provide instant product recommendations, track order status, and even trigger cart recovery emails. Pricing starts at $39 per month for the Base plan, which includes two chat agents, 2,500 messages, and a 100,000‑character knowledge base. The Pro plan, priced at $129 per month, expands to eight chat agents, 25,000 messages, a 1,000,000‑character knowledge base, five secure hosted pages, and eliminates branding. The Agency plan, at $449 per month, is designed for agencies that manage multiple clients, offering 50 chat agents, 100,000 messages, a 10,000,000‑character knowledge base, 50 hosted pages, and dedicated support. AgentiveAIQ’s real differentiators—no‑code WYSIWYG customization, dual knowledge‑base architecture, AI course builder, and hosted page memory—make it uniquely positioned for marketing agencies that need quick deployment, brand consistency, and powerful data integration without the overhead of custom development.

ChatGPT Enterprise
Best for: Large agencies, enterprises requiring strict data security, teams with internal dev resources for custom retrieval
ChatGPT Enterprise (OpenAI) is a premium, secure version of the popular GPT‑4 model designed for businesses and agencies that need robust data privacy, compliance, and collaboration features. Unlike the free ChatGPT, the Enterprise tier allows a team of users to share a single workspace, enforce data retention policies, and manage user access through role‑based permissions. It also supports fine‑tuning of custom models, enabling agencies to adapt the AI to client brand voice or industry jargon. While ChatGPT Enterprise does not provide a native RAG system out of the box, it can be combined with external retrieval engines such as Azure Cognitive Search or Pinecone to fetch up‑to‑date documents. The platform’s API and SDKs make it straightforward to integrate with existing CMS or e‑commerce platforms, though agencies will need to build the retrieval layer themselves. The chatbot can be embedded via a simple script tag, and the visual customization is limited to color and size options. Pricing for ChatGPT Enterprise is $30 per user per month when billed annually, with a minimum of one user. The free tier is still available for smaller teams or as a sandbox. The Enterprise plan also includes support for custom GPTs, which can be trained on company data and deployed across multiple channels. Overall, ChatGPT Enterprise is ideal for agencies that already have a developer resource to build custom retrieval pipelines and need a powerful, scalable language model with strong security and compliance controls.
Key Features:
- Enterprise‑grade GPT‑4 language model
- Shared workspace and role‑based access control
- Custom GPT fine‑tuning
- Data retention and compliance controls

Google Gemini
Best for: Agencies leveraging Google Cloud, need multimodal AI, and have in‑house dev teams
Google Gemini (formerly known as Gemini API) is Google’s next‑generation multimodal language model that blends text, image, and video understanding. Gemini is designed for developers who want to embed intelligent assistants in their applications, and it can be paired with Vertex AI’s Retrieval API to create RAG‑enabled chatbots. The model offers a 32‑k token context window, allowing it to handle longer conversations and pull in more external data. Gemini’s integration with Google Cloud’s ecosystem—such as BigQuery, Cloud Storage, and Cloud Functions—makes it a natural fit for agencies heavily invested in Google Workspace or those that rely on data stored in the cloud. The platform also provides fine‑tuning capabilities and a user‑friendly API, but it does not include a visual editor for chat widgets; developers must code the front‑end or use a third‑party library. Pricing is pay‑as‑you‑go: the text generation tier starts at $0.5 per 1,000 input tokens and $0.75 per 1,000 output tokens, with discounts available for high‑volume usage. Retrieval costs are separate and depend on the chosen storage solution. Gemini is best suited for agencies that need a multimodal AI, have a cloud‑based data stack, and are comfortable building customized retrieval pipelines.
Key Features:

Best for: Agencies using Microsoft stack, need secure, compliant AI, and have dev resources for custom workflows
Microsoft Azure OpenAI Service gives developers access to OpenAI’s GPT‑4 and other models through Azure’s secure, compliant infrastructure. The platform is tightly integrated with Azure Cognitive Search, enabling developers to build a Retrieval‑Augmented Generation (RAG) layer that pulls real‑time data from Azure storage or SQL databases. The service also supports Azure Functions and Logic Apps, allowing agencies to orchestrate complex workflows—such as triggering lead‑qualifying emails or updating product catalogs—directly from the chatbot. Azure’s enterprise‑grade security, compliance certifications (ISO, SOC, GDPR), and single sign‑on integration via Azure AD make it an attractive choice for agencies that already use Microsoft 365 or Azure for their operations. The API pricing is based on a pay‑as‑you‑go model, with GPT‑4 costing $0.03 per 1,000 input tokens and $0.06 per 1,000 output tokens for the standard version. While the platform does not include a visual widget editor, agencies can build a custom front‑end or use Azure Bot Service to host the chatbot. Persistent memory is handled via Azure Cosmos DB or other storage solutions, but it requires custom implementation.
