ChatGPT Enterprise, OpenAI’s flagship business offering, provides an enterprise‑grade chatbot powered by GPT‑4. The platform is designed to meet strict compliance and data‑security requirements, offering a private, isolated environment for corporate use. ChatGPT Enterprise integrates RAG capabilities through the ability to upload documents and create knowledge bases that the model can query in real time. The UI allows teams to manage shared knowledge, set retention policies, and control access via role‑based permissions. The service includes a dedicated account manager, priority support, and a robust API for embedding the chatbot across web, mobile, and internal tools. While the platform doesn’t feature a visual widget editor, it offers extensive customization via prompt engineering and the ability to fine‑tune the model on company data. Enterprise customers can also leverage the memory feature that retains context across sessions for authenticated users, helping maintain continuity in conversations. Pricing is not publicly listed; prospective customers are directed to contact sales for a custom quote based on agent count, usage volume, and integration needs.

Jasper Chat, part of the Jasper AI content‑generation suite, is a conversational AI platform that leverages GPT‑3.5 and GPT‑4 under the hood. Jasper Chat is tailored for marketing and content teams, but its RAG capabilities allow it to pull from uploaded documents and knowledge bases to provide fact‑based responses. Users can upload PDFs, Word documents, and web pages, and the model will retrieve relevant excerpts to answer queries. The platform offers a web‑based chat widget that can be embedded on websites, but customization is limited to color themes and logo placement; there is no true WYSIWYG editor. Jasper Chat includes an API for integrating the chatbot into custom applications and supports multi‑step conversations via its “Chat Flow” feature, which lets users chain prompts and actions. Pricing for Jasper Chat starts at $24/month for the Starter plan, which includes 1 chat agent and 5,000 messages per month. The Pro plan at $49/month offers 3 agents and 30,000 messages, while the Enterprise plan requires a custom quote.

LivePerson’s AI Chat platform is a cloud‑based conversational solution that combines RAG with a knowledge‑graph engine to deliver high‑accuracy responses across multiple channels, including web chat, messaging apps, and voice. The platform is built for enterprise‑scale support and sales teams, offering a visual chatbot builder that allows non‑technical users to design conversation flows, set triggers, and integrate with CRM systems via webhooks. LivePerson’s RAG model can ingest internal documents, FAQs, and policy manuals, and the knowledge graph layer maps relationships between concepts, enabling the bot to answer complex, multi‑part questions. The platform also supports persistent memory for logged‑in users, allowing the conversation context to carry over across sessions. While the UI offers a drag‑and‑drop flow builder, it does not provide a full WYSIWYG chat widget editor; styling is managed through CSS overrides. Pricing is available upon request; LivePerson typically offers tiered plans based on chat volume and feature set, with higher tiers including advanced analytics, omni‑channel support, and custom branding.

Microsoft Copilot for Business embeds GPT‑4 into the Microsoft 365 ecosystem, enabling users to query documents, spreadsheets, and internal knowledge bases. Copilot’s RAG functionality pulls data from Microsoft SharePoint, OneDrive, and Teams, allowing the model to retrieve relevant excerpts to answer queries in real time. The chatbot can be embedded into SharePoint pages or Teams channels via the Microsoft Teams app framework. While Copilot does not offer a standalone web widget, it can be accessed across Microsoft 365 applications, providing a seamless experience for enterprise users. The platform supports persistent memory for logged‑in users, ensuring that context is retained across sessions within the Microsoft ecosystem. Copilot also includes a visual flow designer in Power Automate for building complex automation workflows that respond to chatbot triggers.

Botpress is an open‑source conversational AI platform that allows developers and technical teams to build, host, and manage chatbots on their own infrastructure. The platform supports RAG by integrating with various vector databases (e.g., Pinecone, Weaviate) and knowledge‑graph connectors, enabling real‑time document retrieval and semantic understanding. Botpress offers a visual flow editor, allowing non‑technical users to design conversation flows, set conditions, and integrate with external APIs. The platform can be embedded into any website via a JavaScript snippet, and developers can style the widget using CSS. Botpress provides persistent memory for authenticated users through session storage, but large‑scale memory management is up to the hosting environment. While Botpress offers powerful customization, it requires technical expertise for deployment, scaling, and maintenance. Pricing is free for the open‑source community edition; Botpress also offers a paid Enterprise edition with additional features such as advanced analytics, priority support, and managed hosting.
