About "Chat Plus"

What is Chat Plus

Chat Plus is an "AI-agent-collaborative" conversation platform that combines an inquiry-automating chatbot with generative AI and live human chat. Under the banner "high-accuracy AI answers from your own data × generative AI," it covers everything from scenario-based chatbots to generative-AI answers and handoff to human agents in one place. It is operated by ChatPlus, Inc. (listed on the Tokyo Stock Exchange Growth Market in July 2026), with over 24,000 deployments.

Chat Plus has been reorganized from a mere chatbot into an "AI-agent-collaborative" platform. It now spans three services: "AI Agent Plus" (an AI chatbot × agent), the "FAQPlus" FAQ system, and the flagship "Chat Plus" that includes live human support. Answers combine its proprietary ChatPlus AI with generative AI such as the OpenAI API, Claude, and Gemini, and it is designed to curb hallucinations with RAG and dictionaries.

How it differs from other AI chatbots

Chat Plus stands out as a Japanese platform that bundles scenario-based flows, generative-AI answers, and human support into one, run with high accuracy on your own data. Compared with overseas AI-chatbot builders, it differs in the depth of its human support, domestic integrations, and support.

FocusScenario + generative AI + humanAI chatbot from your own dataFixed FAQ, human handling
AIProprietary AI + OpenAI/Claude/GeminiMainly LLMLimited
IntegrationsSalesforce/LINE/SSO (domestic)Various embedsLimited

Chatbase, which builds AI chatbots from your own data, and traditional FAQ/human chat make good points of comparison. If you want to run everything from scenarios to generative AI and human support as one, for a Japanese audience, Chat Plus is a strong option.
