ChatterMate
Open-source AI customer support agent. Learns your docs, answers with citations across nine channels, and hands off to a human with full context.
ChatterMate is an open-source AI customer support platform, licensed Apache-2.0. Point it at your PDFs and URLs and it indexes them, then answers from them with citations rather than generating unsourced text. Conversations land in one shared inbox where AI-handled and human-handled chats sit side by side, and any chat can be transferred to a person with full context attached. Beyond chat it opens and investigates tickets, builds a branded help centre from the same knowledge base that powers the widget, and qualifies leads mid-conversation, asking after it has been useful rather than gating the answer behind a form. It is built to be run by the people who deploy it: Docker self-hosting on your own infrastructure, your own model keys, a CLI with --json on every command for CI, and an MCP server with revocable access tokens. MCP tools let the agent take real action mid-conversation, such as looking up an order, issuing a refund, creating a ticket or calling your own API. Free forever for the first 300 chats on the cloud, and unlimited when self-hosted.
